php mapscript - can't instantiate second newMapObj?

[Ben Madin]

G'day all,

we have started to see this problem in a reporting system where  
depending on the report, more than one map might be generated in the  
same report (using the same code again)

The first map comes out fine, and then we start building the second  
one (using the same code) and instantiate the same $map = new  
ms_newMapObj().

Warning: [MapServer Error]: loadSymbolSet(): Parsing error near  
(SYMBOL):(line 0) in blah blah

Warning: [MapServer Error]: msCalculateScale(): Invalid image width  
or height. in

Fatal error: Failed loading symbolset from /ms4w/Apache/htdocs/live/ 
mapserver/symbols/colour.sym in


Given that it works perfectly well in many other parts of the same  
application (and this one, if there is only one map) I can only  
assume it is to do with creating another mapObj

I have tried unsetting the $map object, setting it = null, etc, but I  
don't seem to be able to get rid of it.

Can I reuse the class, or is it irrevocably bound up with information  
from the old one.

any help on getting around this would be greatly appreciated.

cheers

Ben
