IOutlineNode.getChildren cause StackOverflowError [message #709812] Thu, 04 August 2011 10:31 Go to next message

I recently moved to Indigo and Xtext 2.0. In my OutlineTreeProvider I re-implemented _createNode(IOutlineNode parentNode, EObject modelElement) for some of my nodes.

If i call the method getChildren() on the parentNode and this one has no children a StackOverflowError raises.
If i call hasChildren() on the parentNode, It always return true even if the node does not have any children.
I attached a text file with the error stack trace.

Am i doing something wrong?

By the way, which is the right way to group nodes in the outline view? Confused

Many thanks!

if I am correct getChildren and hasChildren are not for you to *call* but for you to *implement. The framework will call these methods in order to decide whether there is a subtree and for retrieving the elements of the subtree.


Need training, onsite consulting or any other kind of help for Xtext?
