Here's the source code for this h:dataTable: <h:dataTable styleClass="table" value="#{backingBean.emptyList}" var="result"> <h:column> <f:facet

问题 I have a bean which contains a field of type java.lang.String . This field holds free-form text which can represent a number, string, or date. When the field represents a date, I render a calendar (primefaces) on the screen, otherwise an input box is rendered. The problem I'm having is that after the user selects the date via the calendar, I would like the date string that gets written to my free-form field to have a specific format (MM/dd/yyyy). Currently the string that gets set has the

问题 This question is spawned from the partial answer to JSF2: why does empty test in rendered of panelGroup in composite prevent action from being called?

问题 PrimeFaces conditionally renders the following in h:head: <script type="text/javascript" src="/webapp/javax.faces.resource/push/push.js.jsf?ln=primefaces"><!--//--></script> when PrimeFaces p:socket component is added to JSF/xhtml page.
