JS Client experts:

I’m using the JS Client and running my app in the Omnis Wrapper on iPad.

I like the NativeList control for a number of reasons, but there is a functionality that is missing, the $vscroll property that other list controls have.  Here I’m filling a list and I want to move the current line to the last line in the list, but I also want it to scroll down to show that line.  If the selected line is below the viewable area, it selects the line correctly, but the scroll bar is positioned at the very top of the list so you don’t see the selected line.

Do ivCallList.$select(con("WHERE fCalls.ad_ID =",ivID))
Do ivCallList.$fetch(kFetchAll)
Do ivCallList.$sort($ref.CallDate,kFalse)
Calculate ivCallList.$line as ivCallList.$linecount

# $vscroll is not a property of the NativeList control so this doesn't work
Calculate $cwind.$objs.MainPane.$objs.CallList.$vscroll as ivCallList.$linecount

Does anyone have some other magic way I can get the list to scroll down to this line?

There are other places in the program where I search for a specific record in a list to select it, and if that line is below the viewable area, it’s the same problem.
