Re: [OpenMap Users] When and Where(which object) load the all layser and set the layersMentu inital menu itme according with properties file ("open.layers" ) when the OpenMap startup?

The LayerHandler is responsible for reading the openmap.layers property
and creating the appropriate layers. The LayersMenu connects to the
LayerHandler as a LayerListener, and receives events from the
LayerHandler when new layers are added/removed.

The LayersMenu gets a handle to the LayerHandler using the MapHandler.
All components listed in the openmap.components property of the
openmap.properties file are added to the MapHandler, those that are
BeanContextMembershipListeners receive events that tell them what other
objects are in the MapHandler.
