[udig-devel] Listener doesn't register the first time

[Tiago Silva <eng.tiago.silva@xxxxxxxxx>]

Hi,

 

I've managed to register and listen for the changes in the map. My plugin is now notified whenever the map is rendered. However I need to add and remove listeners whenever different maps are opened and closed. Here are the steps:

 

- Check open maps to see if at least one is open (ApplicationGIS.getOpenMaps())

- If map changed then remove the listeners from the previous maps

- If there are maps then register a listener in the active map and save a copy of the map

 

However the listeners only activate when the map is refreshed.. for example: I open up a map, and nothing happens, I open up another and nothing happens, but when I come back to the first one, the listeners are working... like they were in a queue waiting to be registered...

 

Does anything like this happen? If so, is there anyway to trigger a manual refresh?

 

Thanks in advance,

Tiago Silva
