IBA value updated two times

Hello,

I have implemented a logic where an IBA attribute of WTDocument will get updated at certain point in a change task workflow.

But for one object the IBA attribute is updated two times which is causing some issues in the upcoming activity nodes.

For example: If the attribute name of a document is "Info" and the value I am trying to persist is "value", when the IBA updation logic is executed the value is coming as "value","value".

I can see two entry in the database in String Value table for the document.

Can anyone please shed some light on this?

Thanks and Regards,

Hari R
