[Laszlo-user] Selecting a node in a list to populate a form

[Bryan Barkley]

I believe the datapath attribute must be an xpath expression into a dataset,
not a reference to a datapointer. In your onselect you may want to try
something along the lines of
canvas.userDetailsWindow.datapath.setFromPointer(getSelection()).
