Crash in Chrome/Safari using grid.groupBy

[Sytematic]

Hello,

Using:
SmartClient Version: v8.3p_2012-11-23/PowerEdition Deployment (built 2012-11-23)


In Chrome and Safari, the following stack trace arises, both in dev mode in Chrome (yes i know it's buggy, but just wanted to verify it also happening in offline mode).

Consider a random ListGrid, and call myGrid.groupBy("myField");

The stacktrace i get in Chrome + safari is

15:28:32.946 [ERROR] [generatedcode] 15:28:32.944:XRP3:WARN:Log:TypeError: Cannot set property 'isc_OwnNetworkGrid_0_groupTree' of null

Is this a regression? In Firefox it works, ie. no error is thrown. Haven't tried IExplorer.

Turns out it is a regression. Using the latest nightly of 2013-01-09 it works.
