EL not working across facelet include params

[jgilbert]

I am getting the following exception:

java.lang.NullPointerException
 at org.jboss.seam.core.Expressions.getValidator(Expressions.java:198)

Here is the scenario. I am trying to decompose my facelets into multiple reusable fragments. For example:

EditPanel.xhtml

<h:panelGrid ...>
 <h:outputLabel value="Code" for="code"/>
 <s:decorate>
 <h:inputText value="#{entity.code}" id="code"/>
 </s:decorate>
</h:panelGrid>

I then do an include in various places such as:

<ui:include src="EditPanel.xhtml">
 <ui:param name="entity" value="#{myentity}" />
</ui:include>

The edit panel retrieves the data properly using #{myentity.code} leveraging the entity param.
However, validation appears to ignore the param and uses #{entity.code} which returns null.

Shouldn't this work or is it a seam enhancement? Obviously I can refactor my facelets to get around this, but it would be nice to leverage all the feature of facelets.

why not create tag files? In my opinion they are much better then using ui:include..

Thanks for the food for thought. I haven't tried the tag files yet, but the idea pushed me in the right direction.

It looks like the problem was with the tag I used to start the file.

It needs to be

<ui:composition ...>
 <h:panelGrid>
 ...
 </h:panelGrid>
</ui:composition>

instead of just

<h:panelGrid ...>
 ...
</h:panelGrid>
