I’m having a lot of issues with the reliability of UComboBoxString. The two most reproducible problems are:
- The OnOpening delegate appears to get fired as a result of clicking on the combo box itself while its list is open, despite the fact that this action (as expected) closes the list.
- Double clicking a closed combo box will open and close it (as expected), however in this case the OnOpening is only fired once, yet a subsequent click will fail to open the list, despite triggering OnOpening.
The above issues seem to occur with just a basic setup. I have far more serious problems when trying to use the combo box in a perhaps less standard way - I want to update the contents dynamically, by clearing/adding options either in the tick function or in response to the OnOpening event. When doing so, issues with the combo box repeatedly not opening (despite OnOpening being triggered) are very frequent.
