ArcMap Ver. 10.5, Python Ver. 2.7
Python Add-in ComboBox no longer working.
In versions 10.3 and 10.4 of ArcMap I created multiple Python Add-ins, from the tutorial in the Help to my own custom Add-ins. I am trying to run the Add-ins I have created in previous versions using ArcMap 10.5 and ArcMap the GUI. In all of my Add-ins (which worked perfectly in 10.3 and 10.4) Tools and Buttons work fine, but when I attempt to use the ComboBox, ArcMap crashes and I get the error report window. When I start ArcMap again, the Add-in is still installed, but when I attempt to use the ComboBox again, nothing happens, and no errors appear in the Python window. This also happens in the Add-in example given in the Help Documentation (Creating a Python Add-In Combo Box—Help | ArcGIS Desktop ). I also created a brand new Add-in following instructions in the Help, and it crashes when I use the combobox as well. I cannot find this as a reported bug - has anyone else encountered this problem?
