In order for a layer to be selectable in MapGuide, it must have a
primary key.
Maestro is not good at handling composite primary keys. btw.
To speed up the runtime map/layer creation, the MaestroAPI defers the
primary key lookup
until you actually set the layer to be selectable and visible.
So, when you set the property as below, the MaestroAPI tries to
determine the primary key of the featuresource.
Since you get an "Invalid respository" message, either your "ri"
variable is invalid, or the featuresource it refers to is invalid.
And by "invalid" I mean that it does not start with "Library://" or
"Session:<xxxxxx>//".

I want to add a runtimemaplayer to a runtime map, and write follow code.
ResourceIdentifier ri =
CloneLayerDefinitionForSession(LayerPath, AsLayerName, SessionID);
RuntimeMapLayer rtl = new RuntimeMapLayer(ParentMap);
rtl.ResourceId = ri.ToString();
rtl.Visible = true;
rtl.LegendLabel = AsLayerName;
rtl.NeedRefresh = true;
rtl.Selectable = true;
if (ParentMap != null)
AddRuntimeMapLayerToRuntimeMap(ParentMap, rtl);
return rtl;
The runtimemaplayer refers to a sql 2008 data source.
The bold line of above code can't be executed, the full message is :
