Unable to dynamically filter choice list (show only current + cancelled) in Workspace

[PasipuY]

Description:

I am working in a Workspace and have a requirement on a choice field status.

Requirement:

• The dropdown should always display only:

  • The current status value

  • The “closed” option

• All other choices should be hidden from the user

What I tried:

1. Client Scripts (onLoad & onChange)

   • Used g_form.clearOptions(), removeOption(), and addOption()

   • Initially works for a moment, but Workspace re-renders the field and all choices reappear

   • Also observed “previous value” appearing unexpectedly

2. Different variations

   • Hardcoded removeOption() for each state

   • Dynamic filtering using loops

   • setTimeout() to delay execution

   • Using control.options[selectedIndex] instead of getDisplayValue()

3. Server-side approaches

   • Business Rules (but they only restrict saving, not UI display)

Issue:

• In Workspace, the choice list seems to be re-bound from the data source after client scripts execute

• Any attempt to dynamically remove options is overridden

• This results in:

  • Previously removed options reappearing

  • Inconsistent dropdown behavior

Question:

• Is there a supported way to dynamically filter choice options in Workspace so that only the current value and a specific option (e.g., “closed”) are shown?

Any guidance or best practices would be appreciated.
