GP Loop Block sucks

Hi,

I'm trying to model a process which contains a loop - unfortunatly without any success. Has anybody ever tried this?

I'm using a "Precondition Loop Block" and I would like to have the decision taken automatically. So I tried to use a different CO inside the decision's action as mentioned in the "Designing a block" tutorial.

My favorite CO:

"Decision (Comparison to Predefined Value)"

I may select this, and put in an additional Loop Body Block and do whatever I like. But when I try to activate the process, I get the following error:

"Specify an appropriate decision action for loop. It must have continue and break result states."

But how do I know which one has got these result states? Or do I have to compile one for myself?

I hate it!

Best regards

Daniel
