Don't change the height of the field to match it's contents, set it to the display size. For example, if your field is to *display* on the entire screen, then do this:
set the rect of fld "ViewingField5" to the rect of this card
Then, fill it with the data. Next, set the iOS scroller's contentRect to (the formattedRect of field "ViewingField5"). Finally, in your scrollerDidScroll message, don't set the scroll of the group containing field "ViewingField5", simply set the scroll of field "ViewingField5". Make sense?
Works fine for me.
