[mapguide-users] Display Historival value assigned to a polygon

[Liglio]

If I use a view I will have the problem that a view has no identifier, and
mapguide can't show the features. I am using Postgresql, I already tried to
use FDO schema overrides but the tool gave some errors.

Maybe I can assign the layer to a blank table and insert some features just
for the user map session ?
