It should list them all out when your model is done processing (not stopping
on the first one)

I think it should be there for each cartridge log, so for example in
andromda-bpm4struts.log, you should see something like this:
2004-08-16 23:20:55,437 - performing VelocityTemplateEngine.processTemplate
with templateFile 'templates/StrutsRolesProperties.vsl' and templateObjects
'{xhtml=false, serverValidation=true, welcomeFileName=index.jsp,
applicationUseCase=org.andromda.metafacades.uml14.ModelElementFacadeLogicImp
l[my.onlinestore.purchase.Purchase Items], security=false,
clientValidation=true, securityRealm=other,
[EMAIL PROTECTED], breadCrumbs=true}'
It basically tells you all the info in the template context, does this work
for you or are you looking for something else?
