Fabrizio (the lead developer on the display tag project), took my hack for supporting JSTL's SQL Tag and turned it into a nice feature. The display tag now supports Maps and you can iterate through JSTL's Results using the regular tag or the EL-enabled version. Download nightly build - now automated!
As an exercise for the NYC conference, I implemented an editable table using the display tag. It's a bit ugly, but it does work. You're more than welcome to use it and improve it. ;-) To see it, checkout the following demo pages in AppFuse:
Any feedback would be great.
