Ok, I'll add some more context here.
The event handling code I'm talking about is actually invoked in a
component's /dispatchComponentEvent/ function. It is added as 'before'
advice on this function through a Tapestry Class Transformation.
Basically, the event handling code verifies a boolean an
Any other ideas?

That's possible; I do however perform the test to make sure the URL is only
returned when !request.isXHR() (where request is an instance of
org.apache.tapestry5.services.Request). Is there any other check that I
should perform?

Hi Lance,
Thanks for the quick reply.

3) I think not; my code which returns URLs typically works, but only
sometimes I get the error that a returned URL cannot be handled.
1) Can you clarify this? I don't really understand this question...

Hi Daniel,
Do you allow others to commit to your fork as well? Otherwise, I'd be
interested as I still have an improvement on the latest
tapestry-spring-security which is apparently not yet present in the fork.
Best Regards,

Hi,
We all know Tapestry page instances can be obtained by "injecting" them in a
variable using its type or its name, e.g., as follows:
@InjectPage private HomePage home;
or
@InjectPage("HomePage") private Object home;
However, this method only allows pages to be injected whose names are known

Thanks for the reply, I forgot to mention that in first instance, the table
renders correctly, but it goes all wrong when using the add row link. Could
you try that?
In my case, the new "rows" are shown out of the table (above it to be
specific).

I'm wondering whether it is possible to have an AjaxFormLoop containing

Lance, the 'prepare' event might be fired, but apparently it's not dealt with

Ok, if it isn't persisting the TextField already, I agree with you. But I
thought it did that somehow.

PS: If I recall correctly, a component can only be implemented in terms of
render event handlers, and the activate event isn't a render event
(http://tapestry.apache.org/component-rendering.html). Either way, I tried
to add an onActivate() method to be sure, and it didn't get invoked.

I know, it's only called during (before) rendering.
Anyway, after inspecting the stack trace, I found out that Tapestry is
re-evaluating the /validate/ parameter of a TextField upon form submission.
More specifically, when the form is submitted, the TextField is asked to
validate itself and to thi

Yup, I avoided that code because I'd like the customcomponent to be flexible,
not requiring a specific type of Field in its body, or a specific name for
that Field.
In the meanwhile, I've been able to get the field reference in the custom

Hi,
Well, passing a parameter to the field to configure its validator is exactly
what I'm trying to do. The fields I need already take a parameter for this
purpose (i.e., t:validate), so it doesn't seem useful to extend them to use
Environmentals instead.
The issue here is that t:validate works w

I want to apply the same logic that's applied when using a Page property in
a tml to output text:
I want to use a component's property (render variable in this case) in its
body to set the validator for a field in this body. That doesn't seem too
wrong to me, does it?

Lance,
I'm currently unable to access my workstation, but I invoked the
/resources.getComponentModel().getEmbeddedComponentIds();/ in both
setupRender() and cleanupRender() earlier today. Both invocations returned
an empty list.

Do you happen to know whether it's also possible to inject such a field from
the body of a custom component in that custom component? For instance, let's

Hi,
I was wondering whether it is possible to add Validators to a Tapestry field
(e.g., TextField) at render-time (based on a runtime property)?
More specifically, I'd like to know whether I can avoid doing:

with

Thanks for the tip!
Having read the documentation on Environmentals, it looks to me like I have
to push the required values in the outer component in a method that will
lead to the invocation of the validator method where I need them, and pop
the values, for instance, when this method returns.

Actually, the validator will be applied to a component that's one level
