Only "Classifier Attributes" appear to be changed.

[Woha]

Hi,

my problem is the following: I have an activity with a return value. As long as the return type is declared to one of the basic types from the drop down menu (like "Boolean") I can still edit the normal attributes (right click on activity -> Features & Properties -> Attributes... ) but if i change the return type to one of my own defined typedefs (which is a special class type as far as i understandd) I am not able anymore to edit the normal attributes because if i follow the same process i can only choose classifier attributes now (right click on activity -> Features & Properties -> Classifier Attributes... ). So what can i do to edit my attributes?!

Thanks,
Wolfgang
