yui 2 deleterow

Hello, I am using data table from yui 2.8 and have IE7. In my grid, I have a delete button and on click , I call datatable.deleterow(selectedrecord). All ‘s great except when there is only one record left in grid and i delete. I got error from render method in datatable file with message ‘invalid argument.’
Grid has renderloopsize = 300. If renderloopsize = 0, then there is no error. I got to have renderloopsize set to > 100 as grid has large data.

Has anyone got into this error with deleterow with renderloopsize > 0?
Pls help.
