Bug: Copying output var from Service can cause GUI issues with dataflow #185
Description
Steps to reproduce:
- Create and save a Workflow Sub with base.Text as input and output
- Create a new Workflow Super, calling Sub twice in a row
- Drag the output of the second call into the output of Super without holding CTRL
-> Dragging without CTRL would normaly move a varible; but since the signature of a sub step can't be altered, the move operation is automatically interpreted as a copy operation. However, this does not work properly.
- Expected result: The resulting ambiguity of the output of Super can be resolved by connecting it to the output of either the output of first or the second call of Sub.
- Actual result: It can only be connected to the 1st one.
However, when the variable was copied holding CTRL, everything works as expected.
It seems to be a GUI issue, because the backend gets the same requests and returns the same results regardless of CTRL being used in this case or not. Also, reloading the GUI fixes the problem.
