I haven't been able to pinpoint it exactly, but it seems to be triggered from any external changes or access of files from outside netbeans - causing the tree view to collapse completely has happened in the last few nightlies, most recently tested on todays (nov 15)
figured it out, it's happening when i run my specs - after all specs pass i have it set to run rcov, which dumps removes the root 'coverage' directory, then recreates it and dumps html files into it this causes the whole project tre in "files" view for that project to collapse
Hi Jerret. I've tried to simulate with custom rake task creating, deleting root folder in my project, I've also try to reproduce with rcov running on my Rails project. But never succeed to reproduce. If you would have some simpler steps to reproduce, like "1) create a new Rails project, 2) create a new rake task, 3) run it, ...) it would help.
