[mapserver-dev] Closing a layer removes class expressions and texts (bug or feature?)

[Tamas Szekeres]

Further problem is that if I comment out the related code in msLayerClose,
the second attempt of parsing the same expression will fail
(msEvalExpression). I have no clues to get this stuff working at all :-(

Best regards,

Tamas
