When I use a selectbar as type of an property in a form, it works well when I select it and save the data using a POST to my api. It saves the data correctly. But when I load the form, none of the options is selected. I would expect that the option of the selectbar is activated with a binding of the property.
I use the selectbar with a nullable true/false property.
I've tried to replicate the wrong behavior using our Sample data-source (I've added SelectBar form field to Edit Order Details form with three options) however everything worked correctly on my end:
