[mapguide-users] Not Implemented for MgSelection.GenerateFilter

[Steve Dang]

Darrin, you should head over to ADN dev support for MapGuide Studio questions.

Thanks Steve,

That helped me get past that problem.  I started digging into the underlying database tables and all of the key fields used were int column types.  My layer was pointing to a relatively complex view in SQL server.  A little further looking around and I see that in Mapguide Studio the keys are auto defined, and there is a date in there for some reason.  I changed the feature class used by my layer to one without the date in the keys and did not get the error.

Now I just need to figure out how all these key values are being set and if I can override them.

Is this the correct forum for studio questions?  Or should I head over to ADN dev support?

thanks again for the help.

The problem is from the web tier.  Note that the  MgSelectionBase::GenerateFilter method will throw an  MgNotImplementedException if the property type of the filtered data is not one of the following types:

MgPropertyType::Int16
MgPropertyType::Int32
MgPropertyType::Int64
MgPropertyType::String
MgPropertyType::Single
MgPropertyType::Double

Steve,

I checked the error.log and there doesn't actually seem to be any log generated for this event. I stopped the server service, cleared the log, started the service and then caused the not implemented thing.

Thanks

Hi Darrin,

What do you see in the server log file?

Hi Steve,

Thanks for the suggestion and quick reply.  I had tried MgSelection initially, and changed it over to MgSelectionBase in my trying of things.  I just set it back and am still receiving the Not Implemented error.

One other thing I noticed that may or may not be relevant is they if I right click and quick watch on the mgselection object, the properties are not visible in the IDE.

Below is the XML from my selection in case it is relevant.
<FeatureSet size="1">
<Layer id="4631e36a-0000-1000-8004-0011d8b31fa4">
<Classid="Default:V_FV_BLDG_DOCUMENT">
<ID>VHlwaWNhbCBIaWdoIFJpc2UgT2ZmaWNlAJkAAAAJAAAABQAAADM2MCBDYW1lcmEACAAAADM2MCBDYW1lcmEAbW92AAEAAAACAAAAT2ZmaWNlIC0gTGFyZ2UgMzYwANcHCAENAAAAAAAAAQAAAA==</ID>
</Class>
</Layer>
</FeatureSet>"

Thanks again

Try to use MgSelection instead of MgSelectionBase (e.g. Dim currentSel As New MgSelection(oMap))

Hi,

I'm stuck trying to work with a selection generated from the dwf viewer.  I've been working with the sample in the developers guide but ported over to vb.net.  I'm running MGE 2008.

Basically I go through the motions, create new selection based on the passed selectionXML and everything is cool until I get to the MgSelection.GenerateFilter call.  When I pass the layer object, and the session ID I get an MgNotImplemented error.

I've attached a text file with a bit o' code.  Any suggestions would be greatly appreciated.  I'm sure I've missed something little or done something silly.

Thanks
darrin
