Hello RM-Team,
I tried to iterate over the attributes with the "loop attributes"-operator, but the "select attributes"-operator seems not to work well within a loop

It only work's on the first cycle, thats why I think its not my fault. Could you tell me if this is a bug, and maybe when you will fix it?

Put a breakpoint on the SAtt-operator and see the difference between the output at the first cycle and the other one's.
