Fix JavaScript error when the map panel is loaded in a hidden ExtJS tab #368

Closed marcjansen closed 8 years ago

marcjansen commented 8 years ago

When the map panel is loaded in an initially hidden ExtJS tab, the owner tree is not yet rendered, so call to "node.getOwnerTree()" returns undefined. This caused an error message when trying to call "node.getOwnerTree().getChecked()".
