How to replace the ui_reference query in UI Page with the client side function?

[Anmol12]

II have a requirement in the Risk Assessment where the Reassign button opens the “reassign_coordinator” UI Page with an “Assessor” field. I want to modify the reference qualifier query for the Assessor field to only include members belonging to the assessor group. To achieve this, I created a function in a client script that calls a script include function to retrieve the assessor group members. However, I am unable to replace the current query with my function.
Query which I want to replace with function - query="active=true^roles=sn_grc_reg_change.user^EQ"

<g:ui_reference name="coordinator" id="coordinator_name" table="sys_user" field="name" query="active=true^roles=sn_grc_reg_change.user^EQ" onchange="checkMandatoryFields(this)"/>

I want to replace the query with my function. How should I define it?

Any help is appreciated.

Thanks,
Anmol

Hi Ankur, thanks for looking into this, I need to populate the members only from the assessor_group field only present on the assessment record, how should I query to get the members only present to group at that time?
