You might be able to set the default Facelet or JSP flush size to something large enough to keep everything in memory until your entire paged had finished rendering. However you apparently have large pages that take a long time to render, so it's probably not desirable to do this. If you're able to reproduce the problem, and it sounds like you can, you might want post it here or in JIRA. Someone may find a way of at least preventing Seam from crashing. Or you could take a look at the exception type, and supply custom navigation to an error page asking your impatient users to allow the page to fully render before they start clicking on stuff. :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4039659#...
