Cannot connect to WMS service after editing configuration document

[gBecker]

When editing the configuration document of a WMS FeatureSource in MGOS 3.0 via the editor, the connection to the WMS server fails. Hitting the "Test Connection"-Button results in an unclassified error.

I've also recognized that all entries in the "Select FDO Provider" box exists twice when you have another connection to an older MGOS version aside a MGOS 3.0 server connection in Maestro. For example:

"OSGeo FDO Provider for WMS" and "WMS Provider"

Can you provided detailed steps for reproduction?

[gBecker]

These are the steps to reproduce the problem:

1. Open a connection to a MapGudie 3.0 Server via Maestro
   
2. Create a new FeatureSource of type "OSGeo FDO Provider for WMS"
   
3. Assign a "Feature Server". For example ​http://geoportal.frankfurt.de/opendata/odlb12fbgqgk.exe or any other server.
   
4. Test the connection. Everything should be fine.
   
5. Push the "Advanced"-Button and save the configuration. You don't have to make any changes.
   
6. Test the Connection again: An error message should appear (as mentioned before).

It appears to be an issue with the WMS provider that came with the Preview 1 release.

I do not have this issue with trunk FDO, I'll consider this issue resolved when I put out 3.0 Beta 1

If the duplicate provider entry in Maestro still persists, please move that off to a separate ticket.
