Well, I have a rich:dataTable, and inside its columns, I use to create images dynamically by generating some JFreeChart graphics! However, I am facing a problem. When I render my rich:dataTable, sometimes these images dont appear, probably because the image processing didnt finish! Due to solve this problem, and the user see that there is a processing inside my dataTable, I would like to put a load icon inside of each cell while the images processing dont finish! Could anyone give me a hand?
