[mapguide-users] Dynamically creating a line layer with SDF Feature Source

[Jackie Ng]

Just looking at your code...

Validation is failing because the $featureName should be an enumerated value
( "FeatureClass" or "NamedExtension" )

The value of $featureClass should actually be the resourceid of the layer
definition xml document. The current value should be the current value of
$featureName (ie. $featureClass = "SDF_2_Schema:Selected")
