[Qgis-developer] drill down in QgsValueRelationWidgetWrapper::createCache

[Alessandro Pasotti]

Hi,

it seems that the widget's expression context does not have access to the
currently edited record.

Maybe I've just not found a way to do that but it's impossible to filter
relations with an expression built upon the the values of the "main" record
(the one currently edited in the form) because $currentfeature refers to
the relation layer,

A possible solution would be to add a $currentformfeature to the expression
and add the edited feature to the expression context.

Would it be a possible solution?
Any hint?
