[news.eclipse.tools] Problem with Wizard implementations

[Armin Groll <ArminG9@xxxxxxxxxxxxx>]

Hi,

I have a implemented some export, import and new wizards for eclipse,
and added them to the extension points. All is fine except one thing:
I select my wizard, say, in the Export Dialog. Clicking next will show
my wizard. Clicking back will bring back the wizard selection page. When
I click Next again now, with some other wizard selected, the dialog will
change, but it is empty. So, in fact, invoking my wizard once will take
away the chance to select any of the other wizards on the same wizard
selection page. 

Any ideas on this phenomenon? I waded the code of the eclipse built-in
wizards and my own ones and can't see any differences in principle. 

Thx,

Armin
