Hi all;
Sorry if this is a repeat message. I have been trying to post this few times and I don't see it posted so I am not sure why it is not getting into the mailing list.

I have been trying out AndroMDA for about a month and got to a point where I would like to use more extensive menu structures in my web application in a horizontal Navigation Bar like style instead of the side-bar style in the car rental example (which is a great tutorial example by the way). So after poking around I saw that in the cartridge profile and in the Velocity template for struts-config.xml there is a reference to the struts menu so I added the commented out struts menu template and the struts-config.xml reference (through merge points via "Bpm4StrutsMergeMappings.xml" mapping among other merge-points mappings.
What I get is a Null-pointer exception! Here is a small extract from the bpm4struts log-file:
---------------------------------- Exception error below

--------------------------------- End of Exception Error
---------------------------------------
Obviously the problem starts in the menu-config.xml.vsl when setting:
#set ($root = $applicationUseCase.applicationHierarchyRoot)
For some reason $applicationUseCase is not set properly even if the template in my merge point mapping is the exact copy of the original template from "andromeda-cartridge.xml" which is:
<template
path="templates/bpm4struts/configuration/menu-config.xml.vsl"
outputPattern="menu-config.xml"
outlet="configuration"
overwrite="true"
outputToSingleFile="true">
<modelElements variable="applicationUseCase">
<modelElement>
<type name="org.andromda.cartridges.bpm4struts.metafacades.StrutsUseCase">
<property name="applicationUseCase"/>
</type>
</modelElement>
</modelElements>
</template>
Your help is appreciate specially if you have used struts menu successfully. BTW, I have looked through the messages in this mailing list and in the developer's list and could not find a reference or a bug regarding the use of struts menu so I am assuming it should work. It also possible that I have missed another something.
Thanks in advance.
