Hi Jen,

This could be a product bug, but it's hard to say without more information. Would it be possible for you to post the JavaScript that you're using to insert the dataset rows? It would also be very helpful if you could attach the error log for your server. This file is called labkey-errors.log, and can be found in Tomcat's logs directory. If you used the Windows installer with default settings to set up LabKey Server, you can find this file here: C:\Program Files\LabKey Server\apache-tomcat-5.5.29\logs\labkey-errors.log

Thanks,
Britt
