A popup action in the jsf cartridge causes an exception like reported in the andromda forum http://forum.andromda.org/viewtopic.php?f=30&t=6781
The exception is caused by the andromda popup taglib.
I attached a project with an example usecase with a popup action and popup view which should reproduces the problem.
An other problem is the generated popup view. Namespaces for ui and tr and the body are missing.
I added some more infos to the forum. Should I add it here as well?
