[mapguide-users] Newbie problem with SetFilter

[peter56]

Hallo Kenneth,

thanks for reply. In addition to your indication I found a mistake in the
absolute value for the $featureResId
("Library://downtown/Data/wltg_lin.FeatureSource"). After Changing to 


$featureResId = new MgResourceIdentifier($layer->GetFeatureSourceId());

the code was running.

Thank you, have a nice day - Peter
