GlideModal - Populate other field value based on field value inputted - UI Action in Workspace

[Earl John Vidau]

Hello Community,

I have a custom UI Action that uses g_modal.showFields in Service Operation Workspace.

I want to auto-populate Field 2 based on the value of Field 1 similar to onChange in Client Script

Is this possible or not?

Any luck? Looking to do the same but can't any documention to trigger onChange event for the field values
