To clarify the reason for the restriction, in order to make an Ajax call
to a component we need the component's Url
(AjaxHandler.getCallBackUrl()). This method cannot be called unless the
component 'knows' it's page. (no page, no url...). Before the
restriction the attributes were added in a way I think is incorrect
(directly accessing the AttributeMap in stead of using
AttributeModifiers) and incompatible with TextArea (AttributeMap is
immutable). It did work with TextField, but don't ask me why.....
I'm not completely familiar with wicket's internals, but I think Igor's
solution might work.

ive ran into this myself a few times. especially when i need to know a
path of the component in the constructor, but it has not been added to
the hierarchy yet.
what i was thinking is to add an void init() method to component that
gets called after its been added to its parent component. that way you
can create the hierarchy in that method instead of the constructor.
this can also help with dependency injection because we can initialize
the component before it initializes itself.
i dont really know if this is a place we want to take wicket because
it would make it a bit more managed.
what do others think?

I tried 0.3.1 and found that new restriction is a really BIG
restriction.
I have lots of panel which contains form:
class MyPage extends WebPage {
public MyPage() {
add(new MyPanel("aPanelContainForm"));
}
}
class MyPanel extends Panel {
public MyPanel(String id) {
Form form = new Form("form");
add(form);
TextField field = new TextField(...);
form.add(field);
field.add(new FXValidationAjaxHandler("onblur"));
}
}
Although I can control adding FXValidationAjaxHandler after the
FormComponent
added into component hierarchy. However, Page is still not
available for FXValidationAjaxHandler because MyPanel is not added
into Page yet !
no idea how to fix this.....

We have released 0.31 of the contrib-dojo package (well....
ok, Martijn
did). In this release our FXFeedbackIndicator works when built
in a jar.
(yes... it was a lousy filename-case error). It also has the fixes
previously released in the SNAPSHOT release.
so, feel free to check it out at

p.s. Juergen, this should also fix the bug in our examples
package. So
you could use the War file in the new release for the online demo.
