Error sorting custom formula with grouped Grid on 8.3

[senordhuff]

Hi there, I noticed this problem.

Go here:
http://www.smartclient.com/docs/8.3/a/system/reference/SmartClient_Explorer.html#customColumns

Create a Custom Formula
Group your Grid by any Column.
Sort by the Custom Formula

Then, you'll see the following error. Only tested with Google Chrome. Doesn't appear to happen in 8.2 but found this while hunting down a similar problem we are having with 8.2.

Uncaught TypeError: Object formulaField1 has no method 'getField'

That's been fixed in nightly builds of both 8.3p (the fully patched 8.3 release) and in 9.0 for a while. Please retest with a more recent nightly.
