Thanks, Dennis, for your fast answer.

I will read in docs about how to use "UserInputPanel" and 
"createForUnselectedPack". Thanks for your advice. Can't yet imagine how it 
all could be done with these things, but I'll try, thanks again.

And I'm waiting for your extension :) Really need it now and I'm sure 
somebody will need it in the future :)

Thanks again for your answer!

>I also needed this condition-feature, so I am developing an extension

><variable name="dbtype" value="rdb">
> <removepack packid="pack.db.fastobjects"/>
>This means a variable condition. If the variable dbtype has the value

>Another condition would be a mutual exclusive condition, indicating that

>I hope this will find its way in izPack 4.0 ;-)
