have a strange error that I am really battling to isolate. have a jsf page with validation, using code like: <h:inputText value="#{user.username}" required="true" validator="usernameValidator"> <a:support event="onblur" reRender="usernameValidation" bypassUpdates="true" ajaxSingle="true" /> </h:inputText> I deploy the application (hot deploy disabled, restart JBoss to deploy new version). The validation / form posting on the entire app doesnt work. But after a few hours, everything starts working. I suspect a cache issue somewhere, but have no idea where. I am accessing the application via apache + mod_jk. I restart JBoss, restart apache (which also has no disk / file caching enabled, only mem_cache) and still cant validate immediately after the deploy. the jsf page has no-cache headers too. its definitely not client side. and it does the same whether over http or https. any ideas what could be causing this??
