Here is what I am trying to do:
1. Create facelets source tag:
In taglib:
| <tag>
| <tag-name>address</tag-name>
| <source>xhtml/address.xhtml</source>
| </tag>
|
In address.xhtml:
| <ui:composition ...>
| ...
| <s:decorate>
| <h:inputText
| value="#{address.street}"
| id="street"
| </h:inputText>
| </s:decorate>
| ...
| </ui:composition>
|
2. Now in my facelets that uses the tag:
|
| ...
| <s:validateAll>
| ...
| <v:address address="mybean.billingAddress"/>
| ...
| </s:valiateAll>
| ...
|
|
The facelets loads fine with the address source tag, and when I enter invalid
data in fields from address.xhtml, submit the form and I get the proper
validation error messages, so far so good. But if I enter the valid data and
submit form, I got the following stack trace:

If I change the address.xhtml to use #{mybean.billingAddress} directly like
this:
| <ui:composition ...>
| ...
| <s:decorate>
| <h:inputText
| value="#{mybean.billingAddress.street}"
| id="street"
| </h:inputText>
| </s:decorate>
| ...
| </ui:composition>
|
Then the problem goes away, although this works, but it defeats the purpose of
reusing the tag in several other places.
Any idea?
Thanks.
