Hi everybody!
I have a problem and don't know how to deal with it at all. I have a
datatable with a single column in which I've put a tree table:
<h:dataTable width="100%" var="layerInfo"
value="#{mLayerListForm.layerList}">
<h:column>
<h:panelGrid styleClass="tableColored" width="100%">
<h:panelGrid columns="3">
<h:outputText value="#{layerInfo.layer.id}"/>
<h:outputText value="#{layerInfo.layer.name}"/>
<h:commandLink styleClass="greyBlue">
<h:outputText value="Редактирай"/>
</h:commandLink>
</h:panelGrid>
<h:panelGroup rendered="#{layerInfo != null}">
<t:tree columnClasses="styleText,styleText" var="area"
value="#{layerInfo.areaTree}">
<t:column>
<h:outputText value="#{area.id}"/>
</t:column>
<t:treeColumn>
<h:outputText value="#{area.name}"/>
</t:treeColumn>
</t:tree>
</h:panelGroup>
</h:panelGrid>
</h:column>
</h:dataTable>
layerList is empty and I get:
javax.faces.el.PropertyNotFoundException: Base is null: layerInfo

org.apache.myfaces.el.ValueBindingImpl.resolveToBaseAndProperty(ValueBindingImpl.java:455)

at
org.apache.jsp.pages.LayerList_jsp._jspx_meth_h_column_0(org.apache.jsp.pages.LayerList_jsp:3833)
The strange thing is that the exception is thrown before the
mLayerListForm.getLayerList is called (actually as the exception is thrown
the method is never called). It's MyFaces 1.1.1.
I have not worked with tree or tree table and don't have a clue what the
problem might be.
Please help.
