[Qgis-developer] Atlas export Python script not working in 2.2

[Alexandre Neto]

Hello matt,

That must have to do with the fact that now it's possible to control more
that one map extent with atlas, that means that for each map item you need
to check the control by atlas option.

The same probably applies to the python scripts.

Hope I helped,

Alexandre Neto
