Hmmm. I think you're spot on with your comment about putting the functionality into the row object itself. That's what I was trying to do when I erroneously attempted to bind to the dataTable var. Each row object would be responsible for generating the appropriate components. But it sounds like the row object can only be accessed through its parent dataTable, which I suppose makes some sense.
It finally dawned on me that I need to deal with the dynamic generation at two points - the rendering of the HTML and when the values are posted back to the server. The latter I think I can deal with, but the former has me scratching my head. It seems like I'll need to generate the dynamic components at the same time I initialize the dataTable list (perhaps in a map), and then refer to those components in the column definitions. fastbob Simon Kitching-3 wrote: > > fastbob wrote: >> Is there a preferred JSF pattern for communicating user selection of a >> dataTable row back to the server?
