Understanding Field Behavior

[SeanW6755807862]

Hello,

I'm trying to have a better understanding of the various "moving pieces" that are involved with defining the behavior of a field on a form and how everything works together.

For example, we have a standard/out-of-the-box Caller field on our incident form that references the User table. When the field is populated with a value, two small icon buttons display to the right of the Caller field, but they disappear when the field is empty. I'm assuming a UI Policy is a factor in showing or hiding the two buttons, but I'm not sure I understand what or where the UI Policy is defined or where I can view more information in respect to the buttons and the caller field.

Diving a little deeper into the buttons associated with caller field with focus on only one of them, the 'Show related Incidents'. This button displays a popup a of a list containing incidents submitted by the user referenced by the caller field. What are all the "moving pieces" that make this happen? I understand there is an attribute defined for the field of 'ref_contributions=user_show_incidents' that involves the user_show_incidents UI Macro, but I still don't understand the big picture. Is there an easy way someone could explain a high level overview of the standard/out-of-the-box Caller field's behavior? End goal of all of this would to replicate something similar for the configuration item field for viewing all related incidents submitted for that CI.

Thanks!

HI @SeanW6755807862 

Yes, these two icons only work on reference fields. If there is no value, they show as blank, which is the expected behavior.  I am not sure how much this is doable, here is a reference post of you

But you can check how many incidents has been logged on a CI, go to CI and add the related list Incidnet on CI form and you are done.
