Ryan Slack commented on TRINIDAD-348:
-------------------------------------
I have this problem too, and I have discoverd (via tracing with the debugger),
that the "var" for the root node is not set!
TreeUtils.setDefaultFocusRowKey(..) relies on CoreTreeTable.getRowKey() to
return something meaningfull, however it is returning "null".
getRowKey() uses this line:
if (iState._currentRowKey == _NULL)
(which I assume uses _NULL instead of "null" for some good reason), and thus
assumes that _currentRowKey is either _NULL, or a valid key Object.
However, _currentRowKey gets set to _model.getRowKey(), and _model was earlier
set to UIXTree.createCollectionModel(..), which takes the ACTUAL TreeModel, and
does this this:
model.setRowKey(null);
So even though I tried to have my TreeModel implementation start with a
non-null key, it sets it to null.
What's really crazy is the whole point of setDefaultFocusRowKey(..) is "to
default the focusRowKey to the root node, if it is not set", but UIXTree
ensures that the place it gets the default from is "null"!!!!!!!
SOLUTION:
I *think* the right place to fix this is in UIXCollection.getRowKey
< if (iState._currentRowKey == _NULL)
--
> if (iState._currentRowKey == _NULL || iState._currentRowKey == null)
but this is so very complicated. I need a painkiller.
