[mapguide-users] MapGuide LineRule Label Text Change in RunTime

[Jackie Ng]

Are your primary (water_pipeline) and secondary sources (other_table) from
the same postgres db?

If so, just make a view that is a join of the two tables and style your
layer off of that view (that should appear as a Feature Class).

Or alternatively, make an Extended Feature Class in your Feature Source (the
one where water_pipeline comes from) that's a joins onto other_table and
style your layer off of that Extended Feature Class.

First option is the easiest but may produce un-selectable layers when based
off of a view. You would use Schema Overrides to fix the identity properties
of this view-based Feature Class (see:
http://themapguyde.blogspot.com.au/2010/08/using-fdo-schema-overrides.html)

The second option uses the Feature Join mechanism in MapGuide, which until
MGOS 2.4, was fraught with bugs and terrible performance in the most general
cases.
