Yes, the O'Reilly book has a chapter called "Working with Tabular Data" and a section within it called "Processing Row-Specific Events." Just beware of the one bug in the example code that I mentioned earlier in this thread, and make sure to do a <t:saveState> on your carListBean. I haven't worked with the example in the book for several months, so I'll have to go back to it and try to duplicate the problems Kevin says he has encountered; we haven't noticed any problems in our applications, but there may be some anomalies we're not aware of.

Thanks Brendan! This below looks wonderful. At home now and no time to try it, but will tomorrow from work. By the way, does the O'Reilly book present something like the below? This is the exact kind of example that I think would be very useful to see in a mini-demo-app. On 8/29/05, CONNER, BRENDAN (SBCSI) <[EMAIL PROTECTED]> wrote: > Sounds good.
