Eclipse + SVN Project Problems

I was using Eclipse PDT, the excellent PHP plug-in for eclipse and it was working as a charm. But suddenly it stopped working. No auto-complete functionality any more, the autocompletion stopped working! I found that this happened only with the SVN projects (using Subclipse plugin), and that i had to add this line into the .project file of each project, restart Eclipse and that’s all!
