Musachy, The error displays in the browser, true, but I believe this is because I have: <s:head theme="ajax" debug="true"/> set to show debug.
So this is an ajax/dojo message...? I don't have any code such as: "this.data[x][0].toLowerCase" anywhere in the JSP or javascript sources. Oh, and I have given up on AjaxTags -- it seems silly to include another library to do what is already built into struts. Now if I can just get it to work... Cheers!

I think that error is coming from your jsp, not the JSON generation. Do you have "this.data[x][0].toLowerCase" somewhere? musachy On Feb 4, 2008 11:57 AM, Griffith, Michael * <[EMAIL PROTECTED]> wrote: > Jeromy, > > Again, thanks for the reply.
