ListGrid getRecords throws ArrayStoreException if not all records are loaded

Hi,

It seems that calling listGrid.getRecords() throws an ArrayStoreException if not all records in the ListGrid are loaded when the method is called:

20111028-12:57:38 FATAL (ServerLogImplLog4J.java:72) [btpool0-2] : Uncaught Exception:

I’m not certain but I think this issue was only introduced recently (I upgraded to the 2011-10-28 nightly build) and was not there before. Please let me know if this is a known bug or if you require a standalone test case.

Thanks
