[OpenMap Users] Firing my own LayerEvent?

Hello,

I use a custom mouse mode to manage multiple layers of the same class only
one of which is active (receiving mouse events) at any one time.

The mouse mode picks up the right click and uses that to show a popup menu
with it's items corresponding to the layers managed by that mouse mode.

When the user selects a new layer to activate I want to issue a LayerEvent
to notify all listeners with a setLayers() method of the change.

My first attempt was:

        Layer[] layers = niApp.getMapFrame().getLayers(); // Get all
the layers
        LayerSupport ls = new LayerSupport(this); // Create
support
        ls.fireLayer(LayerEvent.ADD, layers); // Send
out a layer event

This doesn't work because the new LayerSupport instance has no registered
listeners and the fire() method does nothing (Except ignore the request).

I assume that the MapBean/LayerHandler etc has it's own instance of
LayerSupport and that is the one that I need to call to fire() my event. I
can't see a way of getting hold of that LayerSupport nor the list of
LayerListeners.

Any suggestions as to how I might work around this problem?

with regards,

Adrian
