[Qgis-developer] Struggling with iface.openFeatureForm()

[Alexandre Neto]

Hi Bernhard,

Thanks for the link, I guess that the 2.4 problem was already identified
and corrected in master.

A bit of update on this matter. Regarding 2.2. I was doing my tests with a
dbf layer. With a postgis table is working well. So I can work with that
for now.

Still, it seems that there is something to fix in 2.5. should I open a
ticket?
