I installed Flash Player 10 Beta the other day which unfortunately led to about 1 hours wasted Flex Development time this morning when I started work this morning. I tried run a Flex application I’ve been working on in debug mode. Last time I ran it on Friday it worked fine but this time I got an Eclipse alert the moment I tried to run the debug with the following message:
/Library/Internet Plug-Ins/Flash Player.plugin
Flex Builder cannot locate the required debugger version of Flash Player. You might need to install the debugger version of Flash Player 9 or reinstall Flex Builder.
Do you want to try to debug with the current version?
Click yes and the app runs but no debug traces back in Flex Builder.
The problem turned out to be that when I installed Flash 10 Beta Player it overwrote my default Flash 9 Debug Player. I found a reference to this bug in the Adobe Bugs DB. Looks like as OS X specific bug.
If anyones knows how to run the 2 simultaneously please let me know 🙂
