Problem:

This is a bit of an old issue I had a long time ago, but I thought it could save you some time. At the time I was using PDT 1.0.0, a decent performer I must admit, with a lot of external files on remote Samba shares mapped as virtual drives. Some of them were outside of the project scope. A lot of debugging hours were spent to pinpoint the root of the problem – occasionally changes in the remote files were not saved at all. Probably when working with standalone files (not within the project tree) and only with .php editor, I didn’t have the occasion to successfully reproduce it on a 100% basis, so it’s more of a guess or maybe just a sheer coincidence – I’m not sure about it.

Workaround:

For a time a no-brainer solution was to either use Aptana editor or limit editing to local files.

Solution:

Some half a year later (I had a break with PDT for quite a time), the same system configuration and stuff – the only thing changed is Eclipse and PDT updated to their latest, greatest versions – not a problem any more. I’ve rechecked the changelogs – couldn’t find any corresponding bug within fixed issues list. Seemingly, it either got fixed with some other commit or it could have been some more complex issue – maybe involving platform internals – who knows? What’s important - it works! Thank you for the Eclipse team.
