[mapguide-users] QUERYMAPFEATURES

[Lionel Goubet]

Thanks you Bruce for your explanation ...

I added a ticket number #1022


For my problem, I wrote a aspx page which take a polygon and a layer name as arguments
because OPERATION=QUERYMAPFEATURES needs a layer is active. 

Regards,
Lionel

Hi,

You are seeing the error because there are several "SELECTIONVARIANT" values missing from the source code. I believe the reason they are missing is that only the most common ones have been added as not all providers support all of the ones allowed by FDO.


The code that controls this is located in the HttpQueryFeatures.cpp file. Here is the code snippet of what is supported currently:

    // Create the selection variant
    INT32 selectionVariant = 0;
    if(m_selectionVariant.length() > 0)
    {
        if (m_selectionVariant == L"TOUCHES")
            selectionVariant = MgFeatureSpatialOperations::Touches;
        else if (m_selectionVariant == L"INTERSECTS")
            selectionVariant = MgFeatureSpatialOperations::Intersects;
        else if (m_selectionVariant == L"WITHIN")
            selectionVariant = MgFeatureSpatialOperations::Within;
        else if (m_selectionVariant == L"ENVELOPEINTERSECTS")
            selectionVariant = MgFeatureSpatialOperations::EnvelopeIntersects;
        else    // add more values if necessary
        {
            MgStringCollection arguments;
            arguments.Add(L"0");
            arguments.Add(m_selectionVariant);

            throw new MgInvalidArgumentException(L"MgHttpQueryMapFeatures.Execute",
                __LINE__, __WFILE__, &arguments, L"MgInvalidFeatureSpatialOperation", NULL);
        }
    }

As you can see "INSIDE" is missing - along with others.

Please create a trac ticket for this issue as the missing ones should be added. If a particular provider doesn't support the specified "SELECTIONVARIANT" then it will throw an exception and the client will know that it is a provider limitation instead of what is happening now.

Thanks,
Bruce

Hi,


I use
/mapguide2009/mapagent/mapagent.fcgi?OPERATION=QUERYMAPFEATURES&VERSION=1.0.0&PERSIST=1&MAPNAME=MACARTE&SESSION=e4433420-ffff-ffff-8000-005056c00001_fr_7F0000010AF20AF10AF0&SEQ=0.5438243192685027&LAYERNAMES=LAYER1&GEOMETRY=CURVEPOLYGON

and I get a response that I work with ajax/javascript.

But if I change SELECTIONVARIANT=INTERSECTS and SELECTIONVARIANT= INSIDE it doesn't work because the 

Argument(s) incorrect(s): [0] = "INSIDE" L'opération spatiale de l'objet est incorrecte car elle n'est pas reconnue.
Argument(s) incorrect(s): [0] = "INSIDE" L'opération spatiale de l'objet est incorrecte car elle n'est pas reconnue. Une exception s'est produite dans la méthode MgHttpQueryMapFeatures.Execute à la ligne 115 dans le fichier d:\build\carrera_nightly\build_34.2\ent\os\web\src\httphandler\HttpQueryMapFeatures.cpp
Do you have a solution ? 
Must I write a another page (aspx for me) to make this thing ?
Where find documentation on QUERYMAPFEATURES ?

Thanks you very much
