[mapguide-users] Fusion - one AppDef many maps best approach?

[Andy Morsell]

Well, that was easier than I thought it would be.  To accomplish what I
specifically need anyway, which is to pass a MGOS map resource ID via a URL
parameter to Fusion and have it open that map in a given Fusion appDef.  

While researching this, I discovered an undocumented URL parameter called
mapid that was already in the code (ApplicationDefinition.js).  But, I'm not
sure what that is intended for, so I left it alone.   To make this work, I
edited the Fusion.Lib.ApplicationDefinition.Map class with the following
lines:

var paramMgMapResourceId = Fusion.getQueryParam('mgmapresourceid');
if (paramMgMapResourceId.length>0) {
         this.resourceId = paramMgMapResourceId;
}

So, if you pass a map resource ID at the URL, Fusion will pick that up and
use it instead of the one in the appDef file.  In my case, I actually
removed the contents of my ResourceId tag in the MapSet definition.  This
can be tested by making a copy of the Sheboygan map and calling it
Sheboygan_2 (make some changes to it so you can tell the difference between
it and the regular Sheboygan map).  Then, enter the following URL address
into your browser:

http://YOURSERVER:8008/mapguide/fusion/templates/mapguide/slate/index.html?m
gmapresourceid=Library://Samples/Sheboygan/Maps/Sheboygan_2.MapDefinition

Around line 532 of lib/ApplicationDefinition.js there is an over-ride of the
mapid by a query param.  You should be able to do something similar there,
or else just above that in the Fusion.Lib.ApplicationDefinition.Map where it
extracts the resourceId from the MapGroup.

Patches like this would be welcome.  Just create a ticket first and attach
the patch to it.
