[udig-devel] Adding layers

["James Anderson" <jamesanderson274@xxxxxxxxxxx>]

Hello all,

I've just spent the last four hours creating an icon that when clicked will 
automatically add a layer onto the map viewer.  However, whenever I use a 
class that extends AbstractCommand and implements UndoableCommand the icon 
doesn't do anything.  Whenever, I connect the same class to another class 
that extends the AbstractActionTool it does work, but the layer is null.  Is 
there anyway around this?
