> Hi. 
> 
> Im writing a small admin tool for MapServer for own use in PHP with
> MapScript. 
> 
> I'm building a mapfile object with ms_newMapObj() and then 
> throwing elements 
> 
> into database, forms, etc. 
> 
> I've got this problem that when a mapfile has errors (pure 
> simple like 
> 
> 'IMAGETYPE "pnhgg"' instead 'IMAGETYPE "png"') the mapscript 
> parser throws
> an 
> 
> error and the whole application stops. 
> 
> The thing is that I want the application on to at least tell 
> the user, that
> his 
> 
> mapfile has errors and for example open a textarea where the 
> user could edit
> his 
> 
> whole mapfile without throwing it to ms_newMapObj(). 
> 
> I tried many things but nothing seems to work. The thing is, it's 
> 
> msPostMapParseOutputFormatSetup() which actually crashes and 
> which is used
> by 
> 
> ms_newMapObj(). I dont have access to 
> msPostMapParseOutputFormatSetup().
