Hi Thiago!
Thanks for your response
but I do not get you. What do you mean by "checking the generated xml"?
Maybe I have to provide some more info about what I am trying to achieve...
We are using several layers (different SVN's, MVN projects) to create
customized applications just by using java OO principles (means we
override spring services or hibernate entities per layer, override
tml's, thanks to Igor and you we override global message catalogs aso).
Each layer provides it's own module thus is a fully running T5 app and
we can reuse the functionality from each layer without copy and paste.
Unfortunately in my special case I have to override some hardcoded
component functionality from an "upper layer". But just creating a
derived class seems not to be an option as tapestry creates the
components based on the field type and how should it be aware of my
derived component? I found an InjectionProvider but this class only
injecting services, not components. To make tapestry aware of my derived
class I am quite sure I have to specify it somewhere in the ioc config
section. So the ideal solution would be a "component inject service"
which I can use to return "B" in case an instance of "A" is requested...
Sorry english is not my native language so hopefully the description is
understandable. I mean worst case workaround might be to override the
tml, copy and paste the full content and replace the compent "A" by "B".
But intercepting a service would allow me (and all of us) to
transparently inject derivded components without the need of touching tml's.

Hi!
Have you checked the generated HTML?
I have some trouble concerning component inheritance. My scenario is
something like:
A.tml
----
<div xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";
xmlns:p="tapestry:parameter" class="mini-basket-items">
<t:extension-point id="MBIV">
<a href="${valueForA}"/>
</t:extension-point>
</div>
A.class
------
public class A
{
public String getValueForA()
{
return "a";
}
}
B.class
------
public class B extends A
{
public String getValueForA()
{
return "b";
}
}
there is no tml provided by B thus A's tml should be fully reused.
the expression "valueForA" always returns "a" and the overridden
method in class "B" is never called. is there additional
configuration required to make it working?
Thanks again
Jens
