I have a problem with binding to event handlers.
I have two stacked frames placed on mainFrame. Each frame has its own button. When I click on one button, the corresponding frame is removed.
In each frame, I have one list. These lists are in the same position on mainFrame. When I select one item in the first list, it populates another list with new content. Then I press the second frame button to access the second list. I duplicated (with new names) an event to do the same with my second list, to populate the third list.
However, when I select one item in the second list, it seems that the event of the first list is also fired, but only once (if I repeat my selection, it will only trigger the event of the second list).
EDIT: I put a “short” version of my code as requested.
When I select db1 or db2, the first sheet, frame2 goes up and prints test2. Then I select item1 or item2, and how test2 / test1 is printed, not just test1
