I have a reference selector that has a constraint by option set. The constraint works fine if the 'select-using' property is set to 'drop-down', however when the property is changed to 'form' and a form is added the selector does not take the 'Constraint by' option into account. The resulting form should display data in the grid based on the selection made in a reference selector on the originating form and mimic the behaviour as the constraint by option.
