Hi there,
I'm getting an exception when I try removing the last layer from a map using
the Legend. It's saying there are no children left. When I traced through
the calls the problem seems to be in the contextChanged() method of the
Legend class. It calls setSelectedLayer(). Why would it do this when the
layer is being removed? Here's the relevant part of the exception:
java.util.NoSuchElementException: node has no children
at
javax.swing.tree.DefaultMutableTreeNode.getFirstChild(DefaultMutableTreeNode.java:864)
at org.geotools.gui.swing.Legend.setSelectedLayer(Legend.java:387)
at org.geotools.gui.swing.Legend.contextChanged(Legend.java:376)
at org.geotools.gui.swing.Legend.layerRemoved(Legend.java:423)
at
org.geotools.map.DefaultMapContext.fireMapLayerListListenerLayerRemoved(DefaultMapContext.java:864)
at
org.geotools.map.DefaultMapContext.removeLayer(DefaultMapContext.java:331)
at
org.geotools.map.DefaultMapContext.removeLayer(DefaultMapContext.java:314)
Thanks,
Sean
