[protege-discussion] DisplayUtilities.pickCls() problem

[Karol.Borejko at lhsystems.pl]

Hello,

I have some problem with method pickCls(). My code looks like that:

disCls = DisplayUtilities.pickCls(this, getKnowledgeBase(), clses);    
if (disCls != null) {
        setDisplayedInstance(disCls);
}

For some clses the disCls is null and the popup window Select Class 
doesn't appear. For the same clses the code with method pickConcreteCls() 
works.
Does anybody know what is the problem?

Thanks,
Karol
