c#-mapscript: Problem first time calling Map.draw(), numLayers gets one bigger

[Christian Wilmes]

Hi,

if I'm calling the first time Map.draw(), the mapObj-Attribute numLayers gets raised itself from 0 to 1, 1 to 2, 2 to 3.

The next times I'calling Map.draw() nothig happens with the numLayers-Attribut.

I testet it with that 3 cases. What could be the reason for that curious behaviour?

Best Regards
Christian
