Alex, This is indeed a bug in mapserver, symbol indexes are not resolved from symbol names when updating a style from string. You might want to file a ticket and assign that to me in the github issue tracker<https://github.com/mapserver/mapserver/issues/new> .
Best regards, Tamas 2012/11/29 Alexander Schenkel <[email protected]> > Dear all, > > We have the following setup: > > Our features come as DB records out of a PostGIS 1.5 database, which > contains a column "mapserver_style" besides other data columns.
