I have created a datagrid from a javabean, and it works great. My only problem is that I need to change values in specific cells without refreshing the page.
How do I get a reference to an object that represents a row in the grid, so that I can call the setxxxxx() method?
When I have done this, how do I refresh that partikular cell?
As far as I can read on the web, I have to refresh all the cells in the grid. Does anyone know a way to refresh a specific cell???
Thanks

I have used the method of invoking an "onchange" javascript function which passes values to an applet to perform the save. I believe that in order to submit any values from a datatable (or any other component) without performing a client-server round trip, you will need to do something similar.
When dealing with JSF components, you almost always just need to make the trip to the server. Javascript is messy especially when mixed with JSF. The only option I can think of is AJAX (XMLHttpRequest). Getting that to work with JSF is a challenge though.
