Error

[Behnil]

Hi guys,

when I create a simple RCP project, all is OK. I can run it (it's only
a window with one opened editor). But the problems becomes when I
create .product file a try to lunch from it like in tutorial:

http://www.vogella.de/articles/RichClientPlatform/article.html

I get an error like this:

But my class Represented editor has a no-arg constructor. Even when I
run it without .product file, it run correctly. Please, help me:'(

Nobody has an idea? I found out that this problem has to do wit GEF
framework. There are two cases:

1) When I use a target platform with this settings
- deltapack added as local folder
- Eclipse RCP SDK & GEF SDK (both of them added as software
sites)

then I have 181 plugins available (90 from the deltapack and 91
from software sites). And what is important, there is the
org.eclipse.ui.views plugin among them.
I this case, all works perfect.

2) When I use a target platform with this settings
- deltapack added as local folder
- Eclipse RCP SDK & GEF SDK (both of them downloaded from their
official sites and added as local folder)

then I have 158 plugins available and there isn't the
org.eclipse.ui.views plugin among them!
When I run my product now, it crashes with the error above.
