But in the subview, you use #{controller.bldSelectOne}
enhance the bug : Base is null: controller

Ok here is the full stacktrace and the code behind it (sorry for the delay)

<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}"

The funny thing is as soon as I replace the nested aliasbean tag with
a direct call the error goes away.
