Problem with Custom Module When Update Relationship by Subpanel

[PanJun]

Hi,

I have a custom module which is many-to-one account.
When I edit the record by subpanel and assign another account to it. The relationships are not changed. Still keep the previous account.
This only happened on custom module, I checked all out-of-the-box modules, all works.

Any one can help?

Please take a look into the table which stores this relationship.
Maybe the current relationship are not been deleted.
What could be done is to program a logic_hook to identify the new selected account it, and then manage the relationships by coding.
