Q: The dataset generated from the property table cannot be edited, and the new neither. Only when copy the object in the dataset to a new dataset, it can edit. How to solve it?

A: Check whether there is a required field in the property table of the dataset, but there is no default value. If so, it is suggested to create a new field to store this field. Set it to non-required or the default value, and then delete the old field.
