Hello all, 
I'm facing a problem when I try to using Data Binding. 
Actually, this particular variable is already bound but I'd like to change it for another variable and bind it again. 
It should be pretty simple: on the control or indicator, right click ->Properties->Data Binding and select the variable that I want. 
However, when I do that, somehow I can't click OK (please, see the attached figure). 
It's really odd because the variable was bound before. 
I was wondering if someone has any clue why it's happening. 
Maybe something on the settings...
 
Thanks! 🙂
