Flash Builder 4 suddenly stops doing auto-complete

Question

A project we've been working on for weeks in Flash Builder suddenly has stopped being navigable: all the nice features of Flash Builder like auto-completion, jump to definition, even search for References are only partially working -- they work for some classes but not for others. I've tried restarting Flash Builder, closing and opening the project, re-creating the project, but this bad situation persists. Moreover, it happened at about the same time for 2 other developers on the same project, each with a somewhat different configuration. It seems perhaps we have exceeded some internal limit of FlashBuilder, yet our project is not even that large yet. I'm not sure where I can look to troubleshoot this.

Answer 1

I had the same problems, sometimes even code autocomplete was crashing on custom classes.

I would suggest you to try to remove the .codemodel folder from your workspace ,see descriptions here: http://www.redcodelabs.com/2010/05/flash-builder-content-assist-did-not-complete-normally/

And later, to improved performance you can follow this steps: http://www.redcodelabs.com/2012/03/eclipse-speed-up-flashbuilder/

Answer 2

None of these worked for me. My solution is to run a textfactory in BBedit (I'm on Mac) that replaces every tab in my entire codebase with four spaces, then another one that does the reverse. Then I refresh my project in FB. This modifying of every file seems to force FB to rebuild it's references. I have to do it every time I start FB. I'm sure there's a better, command-line way to achieve this (though unix 'touch' doesn't work).
