Common Navigator Framework and LinkHelper [message #639640]

Hi Everyone,

I am having some trouble with the CNF and a LinkHelper. Selecting an Editor does not initially select the corresponding child in the CNF, when the child was not expanded so far. Once it has been expanded, the LinkHelper works fine. In that case i am able to closse the tree view and can re-expand to the child by selecting again the corresponding editor.

It looks like the CNF needs to parse all children once to be able to do the link properly. Is there any way out of this problem?

Cheers

Phil

The problem is probably in your NavigatorContentExtension where it's not properly providing the parent of a given element. The CNF starts with the element that it needs to show and goes up the tree to something that is already visible. If the getParent() of a given element is not returning the right thing then it will have the effect you are talking about.

Hi Francis,

Yes you are right! I just found it an hour before your post. I did some debugging and it was exactly the problem you mentioned:
My ContentProvider was having some trouble in the getParent-Method failing to hand back the root elements to their direct Children. Fixing this solved all the trouble...

Thank you a lot

Phil
