> rich:tab created in c:forEach fails if properties are defined by EL expressions

>                 Key: RF-2215
>                 URL: http://jira.jboss.com/jira/browse/RF-2215
>             Project: RichFaces
>          Issue Type: Bug
>    Affects Versions: 3.1.4
>            Reporter: David M. Karr

>
> This simple test case creates rich:tab elements with a c:forEach inside a rich:tabPanel. The attributes of the enclosed tab are defined by EL expressions. When the page displays, a NPE in org.richfaces.renderkit.TabPanelRendererBase.encodeTabs() occurs. Tracing this in the debugger, the NPE happens because the "name" property of the tab object is null. The value of the "name" property is specified by the "#{property.propertyID}" expression, which should not be null.
> I've tested this scenario in RichFaces 3.1.3 and 3.1.4, myFaces 1.2.2, and Sun RI 1.2_07-b03.
> I obviously don't know for certain if this is a bug in RichFaces, or any of the other various frameworks integrated with this.  it's just a reasonable guess that it is.  I've been pursuing this issue in the various forums with several notes, but I haven't gotten any leads from that.
> I'm going to attach the entire Eclipse project that demonstrates this, which is pretty small.
