I am having trouble connecting a PostGIS database to MapGuide Maestro. Actually, I have added the PostGIS data into Maestro, but when I click to validate the layer it shows an error message:

Validating resource: Session:9754d026-d86b-11e1-8000-00270e208411_en_7F0000010AFC0AFB0AFA//259f852d-fc68-4475-9de1-a5e446fb6e82.FeatureSource Warning - OSGeo.MapGuide.ObjectModels.FeatureSource_1_0_0.FeatureSourceType: Spatial context extent appears to be invalid (or is the default extent returned by FDO provider. Meaning it very likely does not truly represent the extent of your data) Information - OSGeo.MapGuide.ObjectModels.FeatureSource_1_0_0.FeatureSourceType: No primary key defined for class: public:geography_columns, features will not be selectable and feature joins on this class may produce unexpected results

Can anyone please suggest where I went wrong? Is there any documentation for how to add PostGIS data into MapGuide Maestro?

Also, if I click to see the preview of the layer it gives me an error report of Fusion Error.

I am using PostgreSQL 8.4, PostGIS 1.5, MapGuide 2.2 and MapGuide Maestro 4.01

Thanks in advance..

It looks like you need to make sure that your postgis setup is working correctly first. Run some tests? –  janechii Jul 30 '12 at 0:33
    
By keeping coordinate system as default in both map definition and also in application definition the Fusion Error can be stoped. –  kishor Jul 30 '12 at 5:58
    
@janechii Thanks, I will try that now.. –  kishor Jul 30 '12 at 6:00
