[fusion-users] Multiple Maps and OverviewMap.

[Mike Adair]

Tomas,

The map that gets loaded into the MapWidget should be controlled by the 
<MapId> element in the MapWidget, not by the MapMenu as far as I know.  
If that's not the case then yes please file a ticket.

The overview map problem is a known issue:

Perhaps qualify for a ticket? First off it selects the last Map in the Mapmenu as the default but not the first one. So Maps contains 3 maps and the last one is the one that the Map draws. Second, the overview map is not updated when I change maps. Is this already not implemented or do I need to add something more to the AppDef.xml ?

I also get some errors that I think that are encountered with reading between the maps. Just to clear things, I added the MapGroup within the MapSet in the AppDef so I would have two MapGroups and two MapWidgets but I also tried to have two Maps within one MapGroup. Nothing worked.

>> My second question is regarding the OverviewMap. I played a little with the OverviewMap.js and the OverviewMap.xml to see if it would make any changes and nothing happen. Essentially I tried to change some variables like the min and max ratio, oLayerOL.ratio and numZoomLevels but what I'm trying to change in my overviewmap is when you zoom in, in the big map that the overview map doesn't change as well. So after I zoom in 3 times, the overview map starts to zoom in as well and at that time the red binding box in the overview map is so big that it's not feasible to pan around in the overview map. So how can I change the overview map so it that the overview map would never, or after 10 times zoom in. Note: Changing these lines (the value assigned) did not help.
