Sometime clients demands this feaute and I think is unknown funcionality
The LOV component have a property called CreatePopupId where you can indicate the popup that will use for create new rows.
Then above of the table result appear a buton to open the new popup to create rows.
Sometimes we define a LOV in a View attribute but the table is already in the jspx.
We can edit table columns for update to the new component.
First of all. We go to Datacontrols Panel and click refresh icon. Then we select the component table in Structure Panel, now go to the Property Inspector and click a pencil icon.(Edit table column wizard´s opens)
Now we should see the new LOV Type in the combo of the Componente to Use column!
