@zahardev, thanks for the fixes. Please fix the merge conflict and then hit that "merge" button.

On a related note, now that we have fixed https://github.com/GravityKit/Multiple-Forms/issues/103, does it make sense to keep the following?

GravityView/future/includes/class-gv-view.php

Lines 1239 to 1254 in 07e22eb

	// Filter to active entries only
	$status_conditions = \GF_Query_Condition::_or(
	new \GF_Query_Condition(
	new \GF_Query_Column( 'status', $join->join_on->ID ),
	\GF_Query_Condition::EQ,
	new \GF_Query_Literal( 'active' )
	),
	new \GF_Query_Condition(
	new \GF_Query_Column( 'status', $join->join_on->ID ),
	\GF_Query_Condition::IS,
	\GF_Query_Condition::NULL
	)
	);
	$q = $query->_introspect();
	$query->where( \GF_Query_Condition::_and( $q['where'], $status_conditions ) );
