HTML link expression in Custom Attribute Display box?

ChrisWiebke — Mon, 04 Feb 2019 16:38:09 GMT

My working configuration :

custom expression added ({expression\expr2}):

configured attribute pop-up:

My NON-working configuration:

{expression\expr1}

configured attribute pop up:

Why does the working configuration recognize it as a link, but the NON-working configuration not recognize the pop up item as a link?

Thanks.
