subgrid.render() causes "unspecified error" in IE, works in Firefox

[flaggedatbest]

I have extended the subgrids example in the grid tests to include a hidden cell in each subgrid row that can be expanded by clicking on a "+/-" in each subgrid row.

In the toggle for expanding the subgrid row, I indicate the cell should be shown and call grid.updateRow(parentRow);

This refreshes the main grid row, which will refresh the subgrids for that row. Since the subgrids exist, the buildSubgrid findsById each subgrid, and calls render. Render fails with an "Unspecified Error" in IE. No problems with Firefox.

I have a feeling that it has to do with rendering a subgrid in a main grid cell that has not yet been rendered, but I don't completely understand it.
