Hi Igor :)
yes, I've seen a similar thing in the FormInjector's code.
This line does (most of) the trick:
FormSupport formSupport =
form.createRenderTimeFormSupport(form.getClientId(), actionSink, new
IdAllocator());
But unfortunately the form's createRenderTimeFormSupport is in default
scope, so I cannot call it unless I use a component with this
zone-feature (or create a org.apache.tapestry5.corelib.components
package in my project?). In my particular case I'm dependent on a
radio-button, which does not have this zone parameter, yet. Maybe it
would be sufficient if I could call the FormSupportImpl's constructor,
wrapping the problematic functionality in some workaround-component:
FormSupport formSupport = new FormSupportImpl(resources, name,
actionSink, clientBehaviorSupport,
clientValidation, allocator, validationId);
// ... then push formSupport to the environment
This could be done by accessing the form's private members (as I
obviously need the form component's resources, etc.) ... by reflection
maybe? Or is there some Tapestry-Util or service doing that already?
There was something in the TestBase class that I could use:
Field field = findField(object.getClass(), fieldName);
field.setAccessible(true);
return field.get(object);
A better approach doesn't come to my mind now. Better idea, anyone?
What do you think about a JIRA requesting the implementation of the zone
parameter for all AbstractFields? This would be a great addition to the
framework IMHO.
I'd volunteer to open and possibly contribute some time for it ;)
Thanks,
Christian

Hi Christian,
you can also have a look at how TAP5-138 is fixed.

Hi list,
I am currently studying the sources of Tapestry to find out whether or not
I am able to push the formSupport into the environment before the body of a
Zone is rendered.
<t:form>
<!-- here be some control that triggers the zone update -->
<t:zone>
<t:textfield value="i.want.this.to.be.updated">
</t:zone>
</t:form>
I know why it's not working and I've seen the code of FormInjector that
does a pretty good job publishing the FormSupport.
Some other threads in the list about that topic were leading to no
result... but does someone have at least a workaround or maybe an idea for a
possible workaround? :)
Besides that, is there already an issue in JIRA for "Extending a Form with
a Zone"? The documentation at least is mentioning it...
Cheers
Christian
