[Qgis-developer] Edit UI doesn't load the field's value

[Bernhard Ströbl]

Dear Giuseppe,

no, I did not file a ticket for this, although I would support doing so. 
If I customize the default edit-ui via "Layer Properties" - "Attributes" 
and choose a "value map" for a numerical field the resulting ComboBox 
shows the Strings I define but saves the values to the layer's table. I 
had expected the same behaviour with a custom ui but nope.

I do not think they can right now. They would need to do some Python 
scripting, a very good descrtiption is here:
