I am building a fairly straight-forward app and I've changed something in a fairly straight-forward .mxml file and suddenly, whenever I open the file to edit, Flash Builder crashes and dies horribly.
If I comment out all of the code and reopen Flash Builder, I can open and edit the file successfully. I can even put all the original code back in and test the app successfully.
When I have put all the code back in and then go back to edit the file, Flash Builder wipes out in a kind of permanent and irrevocable way so that I have to comment out all the code to get it working again...
I have tried export, delete, import to reinitialise the project, but the problem recurs.
Clearly, I have written something in my .mxml file that sends Flash Builder into some godawful infinite loop or other dead-end, but I am at a loss to say what as it is very, very basic and straight-forward MXML without (as far as I can tell) anything unusual... and I have been programming professionally with Flex for a number of years and built some _big_ applications during that time...
Has anybody encountered anything similar? Any ideas what I might have done?
Found the little git.
Somehow, I had flagged "Enable design mode" and the designer was attempting to render a wide array of custom controls that it had no idea what to do with.
I think, I _may_ have tried design mode for about five minutes about five years ago and decided it wasn't for me... If so, that opinion still holds.
I unflagged "Enable design mode" and suddenly everything is playing nicely again.
