Problems with the nodeFace-attribute and the var-attribute i

[jackasser]

When using the specified var-attribute as parameter to the nodeFace-attribute (as the examples in the live demo do) I get the following error:

"ELResolver cannot handle a null base Object with identifier 'item'"

xhtml:
<rich:tree switchType="client" value="#{pathwayBean.pathwayTree}" var="item" treeNodeVar="treeNode" nodeFace="#{item.type}">

I even tried the samples from http://anonsvn.jboss.org/repos/richfaces/trunk/samples/tree-demo/

I also tried using the latest snapshot of RichFaces (3.3.1-SNAPSHOT).

I actually don't find the error so surprising since the var-attribute simply can't be defined when the EL-resolver kicks-in at the nodeFace-attribute. Problem is, all examples do this and none work so how is it supposed to work?

Could it be some version problem not related to RichFaces itself?

Hello Andreas,

Do you have null tree nodes in the model?

Nope, and more over, if I force the nodeFace-attribute to one of my facet types it will render correctly but of course only use that one type.

Problem solved. I used jsf 1.2_02, apparently something newer is needed. I now use jsf 1.2_11 and everything works a-ok.

Perhaps add some dependency check in RichFaces?

We could not just restrict some libraries usage. Some customers has stricts versions requirements. But for sure we adviced to use newest versions of the libraries because of some issues which could affect all the other third parties.
