Tapestry[5] - Overriding the form error messages
Hi Everyone,
I have a specific message area on the top of the page to display the eror
messages.
I might have more than one form per page,
How can I overide the error messges from the form validation and display on
the message area.
Any Idea?
Thank you,
Anteneh

Re: Tapestry[5] - Overriding the form error messages
Posted by Anteneh Alemayehu <ab...@gmail.com>.
Hi Everyone,
Please see the following fragment code which I tried to override the form
error messages:
The plan is to copy the errors from the validation tracker in to my error
model, and clear the errors from the validation tracker. (At this point I
have the errors in my errors model and also the form is free from errors to
display).
My problem is either
to get the error from the validation tracker by property name
or to get the Field object dynamically from property name
1. Validation tracker has no functionality to get error by property name
2. There is getError by Field, this will be to much work to declare a
component for each field in my form
I can get the List<String> errors from the tracker, but I need Map<String,
String> errors, where property name is a field, to use the information in
MyLabel component, which will take care to hilight the labels.
@Inject
private Environment environment;
MyErrorModel myErrorModel;
private Object onSubmit() {
ValidationTracker tracker = environment.peek(ValidationTracker.class);
Map<String, String> errors = tracker.getErrorsMap();
if (null != getSystemMessages() && !getSystemMessages().isEmpty()) {
List<String> propertyNames = userModel.getPropertyNames();
for(String propertyName: propertyNames) {
myErrorModel.addError(propertyName, NEED_YOUR_HELP);
}
beanEditForm.clearErrors();
return null;
}
displayEmployee.setup(employee);
return displayEmployee;
}

Re: Tapestry[5] - Overriding the form error messages
Posted by Adam Zimowski <zi...@gmail.com>.
I'm also interested to know if individual error messages are
completely customisable in a way that a particular error message can
be styled (bubble or not) and placed *anywhere* on the page
irrespective of where other error messages and form components are.
Without a clear answer so far, does it mean that it is not possible at
the moment?

I agree. I do like the bubbles and I do like the previous style, but
to maximise uptake of T5 it may be best to make the choice of message
display configurable in AppModule and overridable at the page level.
A third display type could also be offered - message alongside/below/
above the field in error (not hovering). CSS for each type would
allow fine-tuning.
Just my two cents worth,
Geoff

Thanks Howard,
I saw that and I personally like the popup bubbles feature,
But there is a requierement to override and display all the error messages
in one specific Message area.
Thanks again,

Starting with 5.0.9, the validation errors appear as popup bubbles
adjacent to the fields.

This doesn't make sense, as there should be no reason to coerce on a
single type (org.apache.tapestry.corelib.components.Form). What does
your Start class look like?

I try to run your codes, but got an exception as follows:
An unexpected application exception has occurred
Failure reading parameter form of component test/Start:errormsg: Could not
find a coercion from type org.apache.tapestry.corelib.components.Form to
type org.apache.tapestry.corelib.components.Form ...
Do I miss anything? Please advise.

what version of T5 are you on? are you using beanedit form? I was
using just a regular form and Tapestry didn't display errors if there
was no <t:errors/>

Good, it is working.
But, how can I stop displaying the tapestry error messages.
I didn't include t:errors tag in my form, but the errors (NOT the bubbles)
are keep on displaying. Unless I clear out the errors from the tracker, I
couldn't stop the errors to display.
Thank you,
Anteneh
