Controller control does not allow Controller refs
Inside a controller I want to add a new Action. When I click on the plus sometimes there is no reaction, i.e., no new action occurs. After a while I get a new action and I was asked for a "target type". The problem here is that the input field does not work to enter something:
you have to choose it from the list, but in the next step "choose an event binding" it is working fine.
