I needed to make some changes to an air application that I made 2 years ago. The thing is: it is still written in flex3 and compiled to AIR 1.5. I didn't have the original project in flashbuilder, so I imported the source code in a new project.
I have tried to compile with flex 4 with backward compatibility, but that didn't work for me. So i deceided to compile with flex 3.5. Everything seems to work, except for the comboboxes.
When I click on a combobox, the dropdown opens but closes immediately. I have searched on this problem, but I cannot find a solution. It is just a standard combobox with 1 dataprovider. So no data is changed.
Does anyone know about this bug? How can I find out the compiler settings from an old AIR file. Maybe I can try to compile with the original SDK.
Thanks in advance!
it is because you must have put editable="true". I had the same issue and solved it.
