[Andrea Peri]

Hi Emanuele,
thx for response.

I try the setExtent , but unfortunatelly it seem don not exist.

Try-ing

    clone_map_getlayer_li.setExtent(extent)

I have this error:

Traceback (most recent call last):
....
    clone_map_getlayer_li.setExtent(extent)
  File "/usr/lib/python2.7/dist-packages/mapscript.py", line 1688, in setExtent
    def setExtent(self, *args): return
_mapscript.layerObj_setExtent(self, *args)
TypeError: in method 'layerObj_setExtent', argument 2 of type 'double'
