Hi Rene,
II think the root problem is the concept of what a "hot field" really is. From my side it's nothing more or less than a way of you adding fields to the generated VIEW. This VIEW is in play when the browse is generated.
When you click on a checkbox, as an EIP column, then the View is not used. thus at this point there's no way to access "other values in the same row" because, well because the server has no memory of the row. If you need to "re-read" the row (the ID of the row is sent) then you need to do that yourself.... sometimes....
Depending on the template settings it may have loaded the reocrd, and it may refresh the whole row when completed. If you look at the generated code you'll be able to see what is happening there in the way of what records are loaded etc. If you need to access other files in that embed, you'll need to open the files yourself.
cheers
Bruce
