I have a project and added a library to it and none of the classes in the library are showing in auto complete / code hinting in MXML. I searched online and read that increasing the memory might help, allowing the type caching to be larger, but I can't find the eclipse.ini or flashbuilder.ini file that they all talk about. I'm using Mac OSX 10.8.
Also, if there is a way to force eclipse to recreate the type cache (classes list) I would rather try that first than mess with the ini file.
FlashBuilder.inishould reside in FB's installation directory, e.g.c:\Program Files\Adobe\Adobe Flash Builder 4.7 (64 Bit)- splash
