[Qgis-developer] update / refresh qgsComposerMap?

[Raymond Nijssen]

How can I update the map in my composer, using python?

My python script changes some layer properties and exports my composer 
afterwards. But I cannot get my map updated before exporting, so my 
exported file still shows the "old" map.

I tried a lot, including:

QgsComposerMap.update()

QgsComposition.update()


but it doesn't work.

Can anybody help??

Raymond
