I created a template using an UDT which contains several TAGs. I can open a pop up from this template using a button, so if I pass some TAGs of my UDT to the pop window I can read the TAGs, but when I write them the changes remains only in the pop up without changing the final TAG. The bidirectional flag is selected. If I make the same job passing the complete UDT, everything works properly. Is it normal?
