ABC File type tutorial with child node bug example

following the filetype integration tutorial:
http://platform.netbeans.org/tutorials/nbm-filetype.html


The child nodes for ABCDataObject's delegate node do not appear in the Favorites window after expansion.

The workaround is to modify the childfactory createNodeForKey method to create
and AbstractNode using the lookup constructor
http://bits.netbeans.org/dev/javadoc/org-openide-nodes/org/openide/nodes/AbstractNode.html#AbstractNode(org.openide.nodes.Children, org.openide.util.Lookup)

and specifying a lookup. In the attached example that demonstrates the bug,
the lookup of the ABCDataObject is passed into the constructor of the children nodes.

It is not documented as a requirement and I don't believe this was a requirement in previous netbeans API versions (<7.1).

I can see one child node. See the attached image.

7.1.2 node expansion not working
Comment 4 gbivins 2012-06-06 12:34:00 UTC 
Interesting...I thought maybe it was due to the version so I up'd to 7.1.2 and I still have the issue. Are you using 7.2 beta or the trunk of NB?
Comment 5 Jaroslav Tulach 2012-06-07 14:21:00 UTC 
I was using three day old build : e.g. from June 4th.
