Hi, I'm runing elcipse 3.0.0 Build id: 200406251208 with MyEclipse 3.8.2 Build id: 200409171200-3.8.2.

When I'm trying to open a js file I get this error: Unable to create part:, without exception.

Any idea about my error.

Regards.
Alejandro

Can you post all the information we request in the Posting Guidelines thread ? Thanks. Also, if you have a non-windows OS, what version of Mozilla do you have installed?

The most important thing here is to open up your log file (workspace dir)\.metadata\.log and see if there are any exception messages after the "Cannot create part".

This is the exception:

Alejandro,
I checked with the devs on this and this was a bug in 3.8.0 that was fixed in 3.8.1... how did you install your 3.8.2 install? Was it an updrade ontop of an upgrade, or a fresh install?

I was a clean install, I've installed all again now with Eclipse 3.0.1 and I get the same error.

I think that is one of the plugins, but I don't know who.

Can you do me a favor and remove oxygen and see if it works all the sudden? I wonder if this bug has snuck back in or it is a new version of it....

Yes it works.

So what can I do?

Don't ever, ever use Oxygen again... no I'm kidding, let me kick this back to he devs and see if we can whip up a quickfix or something for this.

Thanks

Bug was reported here: http://www.myeclipseide.com/index.php?name=PNphpBB2&file=viewtopic&p=20578&sid=be539775630b442f573ef361572cea85#20578

I also have this problem with the *.js editor. I upgraded to 3.8.1 on 03 Sep.
