NamedCollection reference

[Trevor Wekel]

Hi Greg,
 
Many named collections in MapGuide do not allow duplicates because the
name is used as a key.  MgLayerCollection and MgGroupCollection which
are part of MgMap do not allow duplicates.  This might be the cause of
the exception your are seeing.  Do all of your layers and groups have
unique names?
 
Another place to check is the feature properties.  Feature property
names may also be expected to be unique.
 
Hope this helps,
Trevor

I am getting the following error when loading a mg page that retrieves
feature properties from a selected feature.

 

Duplicate object.Duplicate object. Exception occurred in method
CheckDuplicate at line 491 in file
c:\build_tux_area\mgdev_opensource\common\service\data\NamedCollection.c
pp  

 

How do I go about troubleshooting this?
