Please try to add the grid layout to the document, before adding the
tree to the grid itself.

Hi All,
I am trying a simple example of adding a tree to a grid layout. Here is
the sample I am using the following script.
When I run it I get an error in the debug console.
000187:Failed to execute "_modifyParent()":Modification of property
"parent" failed with exception(propValue.getParent() has no properties)
It does not seem to affect the behavior of the tree.

regiontree.add(fldFlorida);
cg.add(regiontree,1,0);
plebis_doc.add(cg);

Any help would be appreciated.
