3 days of ValueEncoder-ing, no coercion found
Hi Tapestry List, long time no hear...
How do you make tapestry spit out what encoder/coercions are supported. My
encoder doesn't seem to be getting registered
I am writing an app and have had to use a ValueEncoder. I don't know where
I am going wrong, I've written them before...and for the past 3 days get
the same stupid coercion message.
My understanding is
1. Write encoder that implements ValueEncoder
2. Contribute to value encoders
3. encoder="myNewEncoder" in the tapestry component to use where no
coercions come out-of-the-box
I have tried two alternatives and would like to know where I've gone wrong
in either please.
1. Using Igor's Tapestry 5 book, I wrote a class called
LibraryEventEncoder and placed it in an uncontrolled package, it implements
ValueEncoder.
package au.com.mrvoip.t5app.encoders ;
public class LibraryEventEncoder implements ValueEncoder<LibraryEvent> {
private LibraryEventFacadeLocal _libraryEventService;
public LibraryEventEncoder(LibraryEventFacadeLocal libraryService) {
this._libraryEventService = libraryService;
}
@Override
public String toClient(LibraryEvent v) {
return String.valueOf(v.getId());
}
@Override
public LibraryEvent toValue(String id) {
return _libraryEventService.find(Long.valueOf(id));
}
}
AppModule receives this addition
@Contribute(ValueEncoderSource.class)
public static void provideEncoders(MappedConfiguration<Class,
ValueEncoderFactory>configuration, final LibraryEventFacadeLocal lqmefl){
System.out.println("CHRIS THIS HAS BEEN CONTRIBUTED";
ValueEncoderFactory<LibraryEvent> factory = new
ValueEncoderFactory<LibraryEvent>(){
public ValueEncoder<LibraryEvent> create(Class<LibraryEvent>
clazz){
return new LibraryEventEncoder(lqmefl);
}
};
configuration.add(LibraryEvent.class, factory);
}
My page class uses a simple grid and the template follows
@EJB
private LibraryEventFacadeLocal libraryService;
@Property
private LibraryEvent lmevent;
@Property
private LibraryEventEncoder libeventEncoder = new LibraryEventEncoder();
public List<LibraryEvent> getLMEvents() {
return libraryService.getMostRecentDistinct("2720101"); //returns a
short list (3-10 results usually)
}
public ValueEncoder<LibraryQueueMemberEvent> getLibEventEncoder(){
return libEventEncoder ;
}
<t:grid source="lmevents" encoder="libEventEncoder" row="lmevent"
rowsPerPage="50" >
<p:empty>
<p>There are no lmevents to display; you can add some
manually when the link is made.</p>
</p:empty>
</t:grid>
And the alternate way which appears to be popular - some private inner
class as a replacement, as well as something like this directly in the get
method.
public LibraryEventEncoder getLibEventEncoder() {
return new LibraryEventEncoder(lmService) {
public String toClient(LibraryEvent value) {
return String.valueOf(value.getId());
}
public LibraryEvent toValue(String clientValue) {
LibraryEvent e =
libEventService.find(Long.valueOf(clientValue));
if (String.valueOf(e.getId()).equals(clientValue)) {
return e;
}
return null;
}
};
}
But all the time I'm getting a problem with coercion of String to
LibraryEvent even with the System.out.println message being spat out of
logs that this encoder is being contributed (or at least i think it is)
Any pointers would be helpful

Thanks for the pointers Taha - interesting that those ValueEncoders have
slightly different behaviours depending
Let me get some traces with a smaller sample project to try and help my
cause.
It's my first tapestry project in nearly a year!

Noted the use of DefaultProvider where grid's is optional.
And yes, I remember reading a million times not to do what I posted - thanks

Hi Chris
You have not shared the trace so I can't help you much but there are certain things I thought might help in general.
Contributing a ValueEncoder to a ValueEncoderSource only helps in components which use the ComponentDefaultProvider#defaultValueEncoder e.g. Select, Palette etc. For a Grid component, encoder is an optional parameter and does not use a default implementation. Thus in your case it is not in use.
As Thiago has pointed out a million times, NEVER EVER initialize a field inline in a component/page use setupRender()/onActivate()
Remember these are not solution to your problem, just suggestions. For a solution please share the full stack-trace :)
regards
Taha

Posted by Chris Mylonas <ch...@mrvoip.com.au>.
Excuse me, the contribute method in the previous email was not the one used
for coercion errors.
It should have looked like this
public static void contributeValueEncoderSource(
MappedConfiguration<Class<LibraryEvent>,
ValueEncoderFactory<LibraryEvent>> configuration) {
configuration.addInstance(LibraryEvent.class, LibraryEncoder.class);
}
and with this one I just implemented the method required for implementing
the ValueEncoderFactory on my encoder.

Damn, I forgot about that possibility. You may have a scalar query, so it
returns a String and not an entity object.

Nabble is good for browsing (I use it for reading and searching old

Oh maaaaaan..... what an idiot. That's a lesson in reading the stack trace
carefully. Bad programmer.
On looking back at the last message, line 31 just had a loop
qmEvents.get(i).getClass.getCanonicalName();
funnily enough as you suspected, the class name was not a
LibraryQueueMemberEvent. It was a String from the database query return,
which is what I was checking for before I came to the list, half-gone-mad..
Thiago, I am sorry to have wasted your time in the end as it was not a
tapestry error.
Noted, re nabble and eating stuff. I just stopped using a dedicated desktop

No every component gets a ValueEncoder automatically from
ValueEncoderSource. Even for the ones who do, there may be situations in
which ValueEncoderSource isn't enough.

Contributing a ValueEncoder to ValueEncoderSource and passing one through
a parameter are very different things and maybe you're thinking otherwise.
When I ask you if you passed a ValueEncoder to a component, I'm asking
about explicitly using the parameter, not contributing to
ValueEncoderSource.

Where's the exception? It seems Nabble ate it. By the way, guys, please
avoid using Nabble.

No. ValueEncoderSource returns a TypeCoercer-backed ValueEncoder when no
contributed one is found for the type.

Cast anything that isn't a String to a String? This isn't expected in
Java, a statically typed language, at all.

For the third or else time, have you checked the actual type of the
objects returned by your persistence provider? They may be subclasses of
your entities.

Nabble ate it again. :( Anyway, it wouldn't help. You need to get the list
and print the class name.
Please print the result of getClass().getName() for each of the

Explicitly providing a ValueEncoder (i.e through the encoder parameter
parameter). I guess you're relying too much on contributions to
ValueEncoderSource even when it's clearly not working.

Oops, now looking again at your post, now in Nabble, I've noticed
something:
Caused by: java.lang.ClassCastException: java.lang.String cannot be cast
to
org.opencsta.ctiserver.library.asterisk.managerevents.model.LibraryQueueMemberEvent
at
org.opencsta.eventviewer.pages.admin2.AgentStatusList.SetupRender(AgentStatusList.java:31)
What's in line 31 of AgentStatusList.SetupRender()? Full method source,
please. Without looking at the source yet, it seems this isn't related to
Tapestry.

Re: 3 days of ValueEncoder-ing, no coercion found
Posted by mvchris <ch...@mrvoip.com.au>.
Hi Thiago,
Thanks for the response, I wasn't aware the Loop/Grid thing was a big issue
- with either template it had been the same, passing the ValueEncoder.
However, since tidying up and gaining a better understanding, the no
coercion exception only appears on a grid - I made all my pages as similar
as possible for this problem since the start of the week to nut it out - so
my question is - how do i know my ValueEncoder is registered with tapestry
or is passed to the grid - since it clearly exists and has been contribtued?
It's as though tapestry can't find it with the grid....and I'm passing it.
Now with the loop component:
Same page class as the last message posted, with this template below, yields
cannot cast exception that follows.
So has my ValueEncoder created the coercion between
String<->LibraryQueueMemberEvent ?
Yet java can't cast between the two for a weird reason?
In one hand (a grid) my value encoder is not recognised, and in the other (a
loop) the coercion has been recognised but at some other level java can't
cast between the two?
With regards to the persistence provider, in this case EclipseLink in
Glassfish - I have no idea about returning a subclass.
The session bean method is
Are you saying you've seen Hibernate return a subclass of
LibraryQueueMemberEvent - and how do you overcome that sort of behaviour?
Thanks for your frustrated reply. I _really_ appreciate your eyeballs on
this thread despite what appears my chopping and changing between Loop/Grid.
Chris

I don't understand this thread. Really. We've noticed the problem is in a
Loop. Now you post a template with only a Grid. I've suggested you to
explicitly pass the ValueEncoder to the Loop's encoder parameter. I said
it may be a problem with your persistence provider could have been
returning entity subclasses in some cases. No response from you for both
questions.

Happy Friday Tapestry Users,
I've been stuck on this all week and really can't move because it's the last
part of my app :(
Then I'm done!! But tapestry is not making it easy to finish.
My ValueEncoder is not getting recognised.
Here's a good summary of it.
1. I use similar (if not the exact same) Object -> T5 Page -> T5 Template
structure between 3 types of objects.
My objects are
a) CTIConfigurator
b) RTQProbe
c) LibraryQueueMemberEvent
And it works for a list of objects when all values in the DB are fetched
from business layer. No need for a value encoder for the grid component on
these.
The page class looks like this for all of these types
And template
And this works.
I then use the same thing for a different object. Using the grid for all
results and it works.
My problem exists when I fetch from the business layer a subset of all
objects of this type, and I get the coercion exception. I don't know why
because it is still a list of objects.
So I make a ValueEncoder for LibraryQueueMemberEvent
And my AppModule has this added to use my ValueEncoder.
It is my only contributedValueEncoder.
I'm still getting a coercion exception on a subset of all
LibraryQueueMemberEvent objects, which are returned from EJB as a list.
The ValueEncoder is declared in the page and template, but somehow not
recognised.
The template
And the page class
There are no typos, I've gone over it with a fine toothed comb.
Help required :(
Thanks
Chris

I took it out when doing my side-project testing.
The findAll() works without a ValueEncoder, yet the other query does not.
Here is a ValueEncoder I have used but no luck.
Why does findAll() work without a value encoder and the other one doesn't?
This part seems irregular.

You didn't explicitly provided a ValueEncoder to your source. Could you
please try that?

Hi Thiago et al,
Sure can, what follows is the template, page class, session bean,
implementation and entity with named queries.
I discovered this behaviour when I ripped this stuff out into a side project
and made a mock list of objects to display...and it worked. Note that there
are no complex types in the entity, all just String/Integer/Boolean.
No value encoder.
findAll() works. Returns 132 objects in List.
getMostRecentDistinctByQueue() does not. Returns 3 objects in List.
I've refactored from LibraryEvent to LibraryQueueMemberEvent overnight as I
work on other parts of the app.
Same exception(s)...
Here is AgentStatusList.tml using a loop
<html t:type="layout" title="About EventViewer"
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_3.xsd">
<p>About EventViewer application ...</p>
id
status
membership
location
queue
<t:loop source="qmevents" value="qmevent">
${qmevent.id}
${qmevent.status}
${qmevent.membership}
${qmevent.location}
${qmevent.queue}
</t:loop>
</html>
And here is the page class
/*

*/
package org.opencsta.eventviewer.pages;

queueMemberService.getMostRecentDistinctByQueue("2720102");
System.out.println("MYLO THE SIZE OF QMEVENTS IS " + a.size() );
return a;
}
}
This is using the Jumpstart method of getting the @EJB annotation to work.
I have had success in using Lenny's Flowlogix library, I'm not at the stage
to incorporate it into my workflow for this project.
Here is the @Local session bean interface

This may be related to the JPA implementation returning runtime-created
subclasses of entity classes (in this case, LibraryEvent). I've seen
Hibernate do that.

You had posted a Grid, but in fact your exception is happening in a Loop.
Could you post the part of the template that declares this Loop instance?

Re: 3 days of ValueEncoder-ing, no coercion found
Posted by mvchris <ch...@mrvoip.com.au>.
OK - I have some peculiar repeatable behaviour... (no use of value encoder
for testing and my findAll() works but smaller subset of results, still
List<LibraryEvent> object used for source)
Whether I use a grid or a loop, my EJB findAll() method which returns all
records - it displays the records without a problem.
If I use my getDistinct() method, I get the no coercion error.
Both EJB methods return List<LibraryEvent> objects.
The findAll() returns 132 in the list, whereas the getDistinct() returns 3.
When calling findAll(), everything works. getDistinct() though, no
coercion.
Any thoughts?
Thanks a lot
Chris
Here is the top of the stacktrace, but it looks like a normal "can't find
coercion" message:

Have you checked in the Tapestry error page exactly where in your template
this happens? I guess it's not related to Grid. As Taha said, there are
some components that need a ValueEncoder but don't get one automatically.
