Re: Help with properties files..

Hi Ed,

The marker name has limited. In the OpenMap application, the
LayerHandler knows it only for a short instant, when it uses the
property to figure out what class to create. After that, only the layer
uses the marker name, in order to scope which properties belong to it
(the LayerHandler tells it what the prefix is). The LayerHandler is the
object that is holding on to all the layers, whether or not they are on
the map.

You can ask the layer what it's marker name is (Layer.getMarker(), or
Layer.getPropertyPrefix()). If you know what the marker name is
programmatically, you could use the BeanContext to get the LayerHandler,
get the layer array, and then search the array for the layer with the
prefix you are looking for. You could also use the layer GUI name
(prettyName property), but that's up to you.

Hope this helps,

Don
