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

[Lime, Steve D (DNR)]

Tamas: Do you have a test script that demonstrates the parsing error you run into? I’ll make this a priority to fix tonite.

Frank,

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,

Hi All,

The current implementation in msLayerClose (maplayer.c line 215-216 in trunk)
removes the expression and text for each class of the corresponding layer. I
doubt if it was a good practice since the second draw of the same map object
yieds different rendering result. Could someone explain how does this addition
make sense?
IMHO the drawing process itself should not alter the map configuration
specified by the user.

Tamas,

There is a ticket on this and I believe Steve will address it shortly once
he better understands why he did it this way in the first place.

It is also breaking some stuff for me.

Best regards,
