did you try the List ( ) function ?
I did try that (list function), but only the first related record is returned in the Tooltip.
List function definition included this text.....If any fields are related, only the first related record is used
Try to attach the ToolTip to the portal and let me know ;)
Attaching a tool tip to an object in the portal row indeed returns the information specific to that related record,
however...I'm looking to place the tooltip on a object outside of the portal, that will return a list of related portal objects in the tooltip text.
e.x. - in a single column list view, hover over an invoiceI.D. field, then it displays a list (description,amount) line items on that invoice in the tooltip text.
Always List !
Try to attach a tooltip to ID with this calc:
List ( LineItems::description )
