Soliciting input from UXD Folks,
Sorry, if you already received this on the jboss-on mail list. Here are the screen shots(4) for BZ 805545 [Improved the usability of the Resource Metric Collection Schedule table]. I had previous left out the last (fourth) screenshot showing a metric collection template being edited, if you read the previous email.
Additionally, here a link to the smartGWT widgets and specifically an example (mass update) that Ian provided that might provide the UI that we are after: http://www.smartclient.com/smartgwt/showcase/#grid_editing_mass_update
Metric Collection for a Resource(http://dell-pe2850-01.rhts.eng.bos.redhat.com:7080/coregui/#Resource/10004/M...)
Metric Collection on Groups (http://dell-pe2850-01.rhts.eng.bos.redhat.com:7080/coregui/#Resource/AutoGro...)

And The drilldown when you click on an item to edit (via pencil)
