The SDx Object Selector input type can be added to a form layout in the j5 IndustraForm Designer.
In order to enable the link back from SDx to j5, the cell's ID should be set to LinkedSPFObjects. It is possible to have more than one cell with the SDx Object Selector. In this case, the main linking cell should be given the LinkedSPFObjects cell ID (only this cell can be used for the link back). This cell ID is automatically given to the first SDx Object Selector input type cell created a form.
