I did change some things in r15054: [FEATURE] feature form updates: - make NULL value string representation configurable - fix feature updates in feature form from attribute table - add support for NULL values in value maps (comboboxes) - use layer names instead of ids in drop down list when loading value maps from layers. - support feature form expression fields: line edits on the form which name prefix "expr_" are evaluated. Their value is interpreted as field calculator string and replaced with the calculated value. - support search for NULL in attribute table I originally didn't want to do the last point, but finally couldn't resist. So there is now a configurable string representation for null values - default is "NULL". By entering "NULL" (w/o the quotes) one can search for null values in the attribute table.
