Write Object data 3 issue

issue 1:
When writing object Attr data, the data submitted on the page is inconsistent with the data in the input box. The submitted data is the old data before editing.

issue 2:
When the write operation is completed, the XML format Value will be stored in the DB, which will cause an exception the next time the Attr data is edited again.

issue 3:
Nothing happens after clicking the Save button of the Object Page, and the edited data is not saved.
