I noticed that a Javascript function I have inside a xhtml page could not reference/find the <h:inputHidden> field by ID unless it was not embedded inside a dataTable. I need to use that function to get the value of a inputHidden field inside a dataTable. Any rules about this? The function seems pretty simple. document.getElementById("elementID"). If the inputHidden was inside <h:form> then the function call works like this: document.getElementById("formID: elementID") View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4096778#...
