When a new object is added to the layout, the painter automatically generates a unique name for it. The format of the name is "Prefix_99999", where "Prefix" is a character string which identifies the object type (e.g. "Label" for a label form field). The automatically generated name can either be accepted or be changed as appropriate. However, names that conform to this format are reserved for generation by the painter. You cannot change a name to a name which conforms to the format "Prefix_99999". When multiple objects are duplicated, or objects are imported, generated or pasted into the layout, the painter resolves any duplicate names by assigning automatically generated names.
