[mapguide-users] Can't GenerateFilter on newly added features

[Bruno Scott]

I have found my problem.
2 things
  1) Identation of the xml layer definition, if we do not respect some form
of identation, it produces weird things
      // Create a line rule to stylize the lines
      string layerDefinition = "";
      layerDefinition += "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
      layerDefinition += "<LayerDefinition version=\"1.0.0\" ...>";
      layerDefinition += "    <VectorLayerDefinition>\n";
      layerDefinition += "      <ResourceId>" + featureSourceName +
"</ResourceId>\n";
      layerDefinition += "      <FeatureName>SHP_Schema:" + layerName +
"</FeatureName>\n";
      layerDefinition += "     
<FeatureNameType>FeatureClass</FeatureNameType>\n";
      layerDefinition += "      <Geometry>" + geometryPropertyName +
"</Geometry>\n";
      layerDefinition += "      <VectorScaleRange>\n";
      layerDefinition += "        <MinScale>0</MinScale>\n";
      layerDefinition += "        <MaxScale>1000000000000</MaxScale>\n";
      layerDefinition += "        <LineTypeStyle>\n";
      layerDefinition += "          <LineRule>\n";
      layerDefinition += "            <LegendLabel>Lines
Rule</LegendLabel>\n";
      layerDefinition += "            <Filter></Filter>\n";
      layerDefinition += "            <LineSymbolization2D>\n";
      layerDefinition += "              <LineStyle>Solid</LineStyle>\n";
      layerDefinition += "              <Thickness>2</Thickness>\n";
      layerDefinition += "              <Color>FFFF00FF</Color>\n";
      layerDefinition += "              <Unit>Points</Unit>\n";
      layerDefinition += "            </LineSymbolization2D>\n";
      layerDefinition += "          </LineRule>\n";
      layerDefinition += "        </LineTypeStyle>\n";
      layerDefinition += "      </VectorScaleRange>\n";
      layerDefinition += "    </VectorLayerDefinition>\n";
      layerDefinition += "</LayerDefinition>\n";
      
 2)
  I was using MgBaseLayer class instead of MgLayer.
  When doing this, everithing seems to works fine except that the
generatefilter does not work
