Cannot debug in Standard mode for iOS due to Flex error

Hi,

I haven't been able to debug my iOS project in standard mode for some time, project just crashed without warning, but I have recently rebuilt my workspace and I am now seeing the error message that, I think, was triggering it...

Either way, I _still_ can't debug in standard mode for this project.

Error occurs on line 2815 of SystemManager code, according to FlashBuilder, with a null pointer for the following:

                var c:Class = Class(getDefinitionByName(mixinList));

                c["init"](this);

I have looked into it, and i is set to zero so the value of mixinList is something like _my_project_name_FlexInit.

Any pointers on how to debug? Is this a problem with my project or with Flash Builder?
