Ok here is the full stacktrace and the code behind it (sorry for the delay)
<h:form id="xxx">
<x:aliasBean alias="#{control}" value="#{bldGmdBezController}">
<x:aliasBean alias="#{holder}" value="#{testLocationForm}">
<f:subview id="simulatedIncludedSubform1">
<jsp:include page="../../inc/webobjects/bld.jsp"
/>
</f:subview>
</x:aliasBean>
</x:aliasBean>
</h:form>
and the subview:
<h:panelGrid columns="1">
<h:selectOneMenu binding="#{controller.bldSelectOne}"
id="selectBld" value="#{holder.bldId}"
valueChangeListener="#{controller.processBldValueChange}"
onchange="document.forms['#{controller.formId}'].submit();">
<f:selectItems value="#{bundeslandBean.items}" />
</h:selectOneMenu>
<h:selectOneMenu binding="#{controller.bezSelectOne}"
id="selectBez" value="#{holder.bezId}"
valueChangeListener="#{controller.processBezirkValueChange}"
onchange="document.forms['#{controller.formId}'].submit();"
disabled="false">
<f:selectItems value="#{bezirkBean.items}" />
</h:selectOneMenu>
<h:selectOneMenu binding="#{controller.gmdSelectOne}"
id="selectGmd" value="#{holder.gmdId}"
onchange="document.forms['#{controller.formId}'].submit();"
disabled="false">
<f:selectItems value="#{gemeindeBean.items}" />
</h:selectOneMenu>
</h:panelGrid>
The funny thing is as soon as I replace the nested aliasbean tag with a direct call the error goes away.

Hi Werner,
Check if myController is not null.

Actually no, if I remove the double x:aliasBean and replace the generic #{controller} again with #{myController} everything seems to work fine gain.
