NullPointer with rich:pickList
Hi,
I'm just doing the first steps with RichFaces and already have a problem ;(
I want to use a rich:pickList in my facelets application but always get an NullPointerException:
Error Rendering View[/presentation/plant_group_demo.xhtml]

..
My view looks like:

<t:panelGrid columns="1" border="0" styleClass="plantdatatable">
<rich:pickList id="picklist2">
<f:selectItem itemValue="a value" />
<f:selectItem itemValue="b value" />
<f:selectItem itemValue="c value" />
<f:selectItem itemValue="suggestion 1" />
<f:selectItem itemValue="suggestion 2" />
<f:selectItem itemValue="suggestion 3" />
</rich:pickList>
</t:panelGrid>
So what I'm doing wrong ?
Thanks, Lothar
