Hi, a general question: is it usual for a tag plugin that alloc is called several times? Everytime I send a message by clicking in the attribute manager the alloc function is called, though it is not used anywhere in the code.Additionally when activating e.g. a checkbox in the attribute manager and I do an undo call, the view isn't refreshed until the tag is deactivated and activated again.
Any ideas?

Really no idea? Every time I drag a slider or activate a checkbox "alloc tag" is called. This leads to some serious problems with undoing. Some help would be fantastic... Thx

What you seeing here is Cinema's undo/redo system at work. It has to create instances when you change something in the AM and free them if you are undoing things.

OK, I'm sorry for the confusion:) This is the first time I try to understand the undo behaviour and I still didn't really succeed. Somewhere I read that Attribute Manager items like checkboxes are handled automatically and that causes a lot of trouble. Before the Message-method is called, it creates an instance (for the undo call?), and it doesn't work properly with Message() :

I assume I do not work correctly in case MSG_DESCRIPTION_CHECKUPDATE. Does anyone see the problem?
