LABELITEM Using Variable Substitution

[Steve Lime]

Labelitem is not one of the parameters that support runtime substitution. Those
that do are typically of the type where you would only want to replace a portion
of the variable such as a FILTER. For a labelitem you can use syntax like:

  map_layername_labelitem=...

I am having problems dynamically setting the column used by the LABELITEM
property.  MapServer is not substituting the parameter passed in the WMS
call.  Instead, it is using the parameter name as the column name and
MapServer returns an error stating that the columnParameter column is not
found.

The format of the LABELITEM definition is:
    LABELITEM '%columnParameter%'

I am using Windows, MapServer 4.6.1, and have been able to successfully
use variable substition with the MapServer FILTER command.

Any help would be greatly appreciated.

Thanks,
Rafe
