Flex Combobox closes automatically

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!

Have you tried adding a second item to the data provider? Could be some odd logic in Flex that is closing it because there is nothing to select from. – sean
There are multiple items in the data provider. In some cases 5, in some cases between 50 and 100. – VeeWee
combo box close usually when they loose focus. I would look into a focus change event – The_asMan
Problem is currently solved: I tried all the different SDK's from 3.0 untill 3.3. This 3.3 SDK solved the problem. Looks like i'm not going to be able to use newer functions. – VeeWee

it is because you must have put editable="true". I had the same issue and solved it.
