Re: [OpenMap Users] No LayerEvent.REMOVE delivered on layer deletion???

Hi Adrian,

The REMOVE event doesn't get fired anymore, it turned out to be
redundant when the other two events were fired. The ALL event notifies
everyone which layers are available. The REPLACE event notifies
everyone which layers should be on the MapBean.

These events were names to mean something to the MapBean. When other
components started listening for them, we just kept the names as they
were.
