[mapguide-users] Cannot Create Layers From Feature Sources

[gom]

Further to my difficultiess with unmanged data sources in 2.4, I wonder if
the following images help.  As you can see the schema name is different in
the two previews of the same data source.  If I do this comparison on the
same datasource under 2.2 the names match.  This suggests to me an issue or
possible answer as to why I cannot create layers from these datasources?  I
have no idea why the difference exists but it happens to anything I import
from a package or anything new I create.  *Schema Name of data source as
shown in Maestro using the Preview function on the Toolbar.  This is the
correct or expected name.* schema1.png
