Refresh a related list on field change

[oharel]

Hi guys,

Is there any way to refresh a related list when a field changes on the form?

For example: if I change the category on an incident form, I would like the related list category-articles to update, without saving the form first.

I tried an onChange client script with the following:

GlideList2.get(g_form.getTableName() + '.REL:31336814db772200e4257cbdae9619f4').setFilterAndRefresh('');

But I am not sure it can work without saving the form, which sort of makes this irrelevant.

Ideas?

The wiki says that g_list is used in UI Context Menus and UI Actions:

Thanks Ankur,

Already checked those...

I'm afraid Mike is right (that is, I'm afraid I can't do what I want, not that Mike is right...)

Thanks guys.

If you don't mind venturing into the DOM, adding this line to onChange will refresh the Related List:

document.querySelector('div.related[tab_caption="Task SLAs"] span.breadcrumb_container a:last-of-type').click();

where "Task SLAs" in this example is the label for the Related List. It clicks on the last filter condition of the breadcrumb to make sure you apply and retain the entire filter.

Using GlideList2 like below works as well, but I noticed it filters only on the default filter condition (because we're not passing the filter as an argument), losing the rest of the breadcrumb in case you have multiple filter conditions:

GlideList2.get(g_form.getTableName() + '.task_sla.task').setFilterAndRefresh();

If you want to mimic the construct of the GlideList2 line above, you can use

document.querySelector('div[tab_list_name_raw="' + g_form.getTableName() + '.task_sla.task"] span.breadcrumb_container a:last-of-type').click();

EDIT: replaced :last-child with :last-of-type, which makes it more specific

Hope this helps.
