hello, i have a page that contains a rich:dataGrid of rich:panel's. when one of the rich:panels is clicked, i want to be able to click the panel and have it be highlighted or change to a different color. i've implemented it to have the rich:panelGrid change background color on click but i really want the whole panel to change colors. also, when another panel is clicked the previously selected one should change back to normal color. does anyone have any ideas on how to do this?
