Hello,  
We have a detail form and respective list form with our custom list-component.For our custom list-component we have same .spec file as that of bootstrapcomponents-table, although when we run our forms initially even before the list form is visible on screen/list is initialized we get below error for the valuelist. Is it because our valuelist was initialized by textbox/dropdown component and it still tries to rebind?

```auto

Please edit these dataprovider(s) (using table editor for database column or Edit variable context menu action for variables) of this valuelist: price_rule_price_rule_type so that they have the same type.
