I am calling apex.item("name").node.setCustomValidity("error message") form several items on my page. When the code is executed, I can see all of the messages and the red outline on all of the page items EXCEPT those that are rendered as Popup LOV's.
I examined the items and the have the correct class applied, apex-page-item-error, but the CSS rule is being overruled on the Popup LOV's. I can also look at the error placeholder for these items, but it is blank. The other items that have an error have a non-empty "div" when they are invalid.
I am using the Universal Theme in APEX 20.2.
Thanks, DaveR.
