I am using a <rich:tabpanel> with 3 tabs. In the 2nd tab I have 3 <rich:fileUpload> components. All the 3 fields are mandatory. Hence I perform validation in the backing bean on submit of the contents in the page.

If I select a file in one of the file upload components and leave other 2 empty, then I get the validation messages for the 2 empty components as expected. However the first component is also re-rendered and is not retaining the selected file, even though the file contents are still stored in the property of the backing bean.

How can I retain the selected file on re-render?

    Just do not re-render the input fields itself, but only the holder(s) of the validation messages. You can do that with <a4j:commandButton> wherein you specify the IDs of the message component(s) in the reRender attribute (I am assuming that you’re using RichFaces 3.3, not 4.0, as it’s not by default possible to have a single file selection for file upload in the current 4.0).

    Note that you don’t need to validate for requireness in the action method. Just setting required="true" on the input component(s) is sufficient.
