GRID ArrayIndexOutOfBoundsException

[jfisher]

A ArrayIndexOutOfBoundsException is generated when a Grid Store has no values. For instance, I configure Column headers, but the store has no data. The Grid renders itself with headers, looks ok, no data (which is what is expected), but when a column is clicked on (ie to sort) then a ArrayIndexOutOfBoundsExcpetion is generated (uncaught exception).

Take a look at the samples code for GRID, choose any, but have store have no values (null).

How can excpetion be caught, or is this a bug in class?

I have not been able to reproduce this issue (tried empty stores). If you are still seeing the exception, can you post sample code?
