Quick follow-up. It does appear to be important that a dynamic column have a
valid dataField property, even though it has a labelFunction to actually
determine the displayed value. I ran into a situation where the little
triangle was jumping from the currently sorted column to the first column
Yes, it's in an override of set dataprovider which calls super (I would not
have done things this way).
And it does sort correctly initially. It's only when I click on the column
that I get the error.
One thing I'm asking myself is if it's harmful or just redundant to specifiy
dataField if you
You should always specify a valid dataField.
If you have null data items or items that are dynamic and missing properties
you can hit this error.

Original question:
Is there a recipe for sorting initially on a column which has a computed
value in it?
I put together the example below which works great. I'm not sure what's
triggering the error in the actual code I'm dealing with, but this example
convinces me it's time for some refactoring.
And it appears the error *was* caused by having a column with a value for
both labelFunction and dataField.

I doubt that would be true unless the dataField was didn’t exist as a top-level
property in the data objects. I ran your test case and never got any error.
Looking at the code, I don’t know why you need two sort functions. They look
the same. Also, I would apply the sort after setting the
Lots of crossed wires here. Sorry I wasn't more clear.
My last two messages were the solution for the benefit of others, not
further puzzlement.
Yes the test case I included runs perfectly, as I said.
Yes, a specified dataField must exist. The code I inherited had both a
non-existent dataField
I'm thoroughly confused by the DataGrid sorting stuff.

Some code I inherited is doing this by overriding the dataprovider setter
and calling
if (sortEventCounts value is ArrayCollection
Also assign the sortCompareFunction to the column.
