[fusion-users] Mapguide Eventhandling with Fusion.

[Tómas Guðmundsson]

Paul,

I tried this and it works but it gives me an error. 
Inside the function triggerEvent on line 1041 inside
fusion.js it gives me an error with a popup alert :
Fusion Error:
WARNING: Exception occurred in AJAX callback.
TypeError: this.events[eventID][i] has no properties
Location: undefined (1041)
xx)

Where undefined is actually fusion.js and line 1041.
Here is the function I have running in a javascript
widget that is being executed.
this.getMap().registerForEvent(Fusion.Event.MAP_BUSY_CHANGED, alert('MAP_BUSY_CHANGED'));

Regards,
Tómas.

Tómas,

these are not the droids you are looking for!  These events only  
relate to loading the map definition from the server, not drawing the  
map.  You want Fusion.Event.MAP_BUSY_CHANGED.  This gets called when  
the map starts drawing and again when it is finished, but you need to  
check map.isBusy to see if the map is still busy or not because  
several busy states can be queued up.

Cheers

Paul
