T5 Loop
Hi,
I am trying to iterate over a list and display the values in a
textfield. User can edit these values and i need to save these back
to the list. I am able to display all the values, but the values are
not getting updated when user saves them.
<span t:type="form">
<span t:type="Loop" source="values" value="value" >
<span t:type="textfield" value="value"/>
</span>
<span t:type="submit"/>
</span>
Is this possible ? i searched in the mailing lists, but couldnt find
any information.
Thanks

Thanks again, Howard!
I think T5 is definitely going to be a great thing!
I'm going to donate, and hope there would be good funding for it.
Thanks!

I'm in crunch mode for two different clients at the moment, which is
why I've been slow to get more T5 code out.
As a side note ... if anyone want to *fund* the development of T5,
that would get it out the door much, much faster.
In terms of T5 status:
Uploads are coming.
Returning a custom URL from a T5 event handler method is either in
place, or coming.
You have full access to the Servlet API objects, or to the generic
Request and Session objects, to allow you to manipulate request and
session attributes. Over time, more of the HttpServletRequest methods
will be re-implemented in the Request wrapper.
The trick is allowing outside servlet code to access the Tapestry
objects (even if stored in the session), in that you can't predict
what the session attribute key is going to be (the name used is
predictable ... but subject to change at any time. It's part of the
Tapestry internals).

Thanks for clarifying this, Howard!
Now actually, i have related questions: My application needs to handle
file uploads, and work with third-party packages to generate graphs
(through generating from the backend either a custom link or javascript
for the html page), and occasionally redirect to non-Tapestry pages or
URLs, maybe manipulate the request, response and session objects when
necessary. I'm not quite confident whether I can achieve these by using
the current unfinished T5.
Do you think I can actually manage? What are the recommendations?
Any help is greatly appreciated!

T5: Hibernate integration question
Posted by Celia Mou <cm...@ocean7.com>.
Hi,
Does anyone have a working example of Tapestry 5 and Hibernate integration?
According to the limited docs on the Tapestry site, one needs to put the
hibernate.cfg.xml file in the src/main/resources directory, and then
maybe contribute the entity package to the
tapestry.hibernate.HibernateSessionSource. It seems if one has the
entities package under the base package, one doesn't even need to
contribute.
That's what I got. But then, where would you put the mapping files? And
what's the typical way to instantiate and destroy Hibernate sessions?
Well, in short, I'm a bit lost in this. Any hint will be greatly
appreciated. Thanks!

Howard,
Thanks a lot for responding. I tried setting the volatile="true" for
the Loop component, but i still have the same issue. When i try
printing the first element of the ArrayList on the onSuccess method,
it still shows the old value.
Start.html
------------------------------------------------------------------------
----------------------
<span t:type="form">
<span t:type="Loop" source="values" value="value" volatile="true" >
<span t:type="textfield" value="value"/>
</span>
<span t:type="submit"/>
--------------------------------------------------------------------
Start.java
------------------
public class Start
{
@Persist
private ArrayList<String> values;
private String value;
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
@SetupRender
public void fillValues()
{
System.out.println("fillvalues------------");
values = new ArrayList<String>();
values.add("test");
values.add("test1");
this.setValues(values);
}
public ArrayList<String> getValues() {
return values;
}
public void setValues(ArrayList<String> values) {
this.values = values;
}
String onSuccess()
{
System.out.println(this.getValues().get(0));
return null;
}
}

Re: T5 Loop
Posted by Howard Lewis Ship <hl...@gmail.com>.
This should work, but it looks like you simplified your example.
The Loop component records into the form (as hidden fields) the values
from its source parameter. When the form is submitted, it uses these
values, and ignores it source parameter.
In the short term, you should be able to get the Loop and Form combo
to work by turning on the volatile parameter of the Loop. In the long
run, you should provide a PrimaryKeyEncoder to the Loop, to guide it
in how to serialize the dynamic data into the Form.
