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. <http://osgeo-org.1560.n6.nabble.com/file/n5004980/schema1.png> Schema Name of data source as shown in Maestro using the Local Preview function <http://osgeo-org.1560.n6.nabble.com/file/n5004980/schema2.png> Cannot Create Layers From Feature Sources Sep 20, 2012; 3:43pm— by gom I have a number of unmanaged SDF files in a folder. (2 point sdf files, 3 polyline (curve) sdf files) I have them authored/working nicely on an active Mapguide 2.2 server 32 bit version on IIS. I exported them as a package and imported them to my development workstation. Windows 7 Professional, Mapguide 2.4 RC1. I have another test server Windows 2008 IIS with 2.4 RC2 64 bit where I did the same. The data files are available for authoring in the Mapguide Studio/Maestro programs. I can create data sources and use the preview functions on the programs to view the schema, attributes etc with no trouble. I see a valid geometry property. In addition I can preview the features and see the objects drawn as expected. Permissions seem to be consistent across the three machines. All the layers for 4 data sources are broken. When I go to modify a layer, and select one of the 4 data sources, I get an errors. When I try to create a new layer I get the same errors. Re-creating the data sources makes no difference. (One of the polyline data sources is still working as expected). I edited and saved each file in AutoCAD map to ensure I could read/write them successfully. In Maestro 4.0.2 it says “Feature Source (xxx) has no usable feature classes. Choose a different feature source.”, then it says “The Resource ID could not be found.” In Mapguide Studio 2010 and 2011 it says “Object reference not set to an instance of an object.” The layer dialog shows the selected FeatureSource name and the expected schema in the dropdown list but Geometry drop down has no options. I have tried every variation of new feature sources and layers but no luck. Is there something I am missing? Can anyone suggest some different tests or approaches I can take to sorting this out?
