I have a portal on my layout with 2 buttons.
One button is a delete button, which deletes the portal row and commits.
The 2nd button is a Popover button that pull from another table. The Popover displays another Portal if activated.
This Popover button has conditional formatting to change the color of the button to blue if the Portal within it has records.
It only appears in the first portal row despite how many records there are. This button's, "Hide object when", value is:
IsEmpty ( Software::ID )
"Software" is the table name associated with this main Portal.
The only thing I can thing of is that Popover buttons don't work in Portals like this. If that is the case, is there a workaround?
