Problems getting jsp:include to work

[dkarr]

JSF 1.1, RichFaces 3.1.3.

I have a tabPanel where some of the tabs will work identically, such that they will have the same fields, but each instance will go to a different array entry in the backing bean. I've tested and verified the functionality "inline" in the main page, but I think it would be better if I moved the content of the tab into an include file and use "jsp:include" with a parameter from the main page.

On the first try, I'm not even using the passed parameter in the include file (just using a default index of 0 for now). I'll integrate that when everything else is working.

When I first tried it, my "jsp:include" looked like this:

<f:subview id="propertysubview0">
 <jsp:include page="/propertyTab.jsp">
 <jsp:param name="propertyIndex" value="0" />
 </jsp:include>
</f:subview>

When I ran this, it gave me an error like:

Error testing property 'propertyID' in bean of type null

I then realized that perhaps my include URI should be "/faces/propertyTab.jsp" (that's the mapping to my Faces Servlet). After I made that change, I instead got the following exception:

java.lang.NullPointerException

My included JSP looks like this:
