问题 I am using <p:fileUpload> component. Is it possible to preselect and show the selected file in field before the browse button? I am using Mojarra 2.0.3, PrimeFaces 2.2 RC2, GlassFish 3. 回答1: No, if this was possible, this would have been a huge security hole.

问题 I am working on an application where I would like to include dynamic XHTML content from a stream. To handle this I wrote a taghandler extension which dumps the dynamic XHTML content to output component as UIOutput htmlChild = (UIOutput) ctx.getFacesContext().getApplication().createComponent(UIOutput.COMPONENT_TYPE); htmlChild.setValue(new String(outputStream.toByteArray(), "utf-8")); This works fine for XHTML content which has no JSF tags.

问题 According to this blog JSF is going stateless . Isn't the whole point of using JSF is that it makes saving and restoring state a chore . What is the point of JSF becoming stateless ? Can you please provide an example where this can be useful . 回答1: First of all, I would like to clarify that JSF isn't exactly "going stateless" at its whole own. JSF just adds a new feature enabling the developers to create stateless views/forms on demand. State saving is particularly helpful in dynamically
