Question

This is the controller:

Answer 1

The problem was the a4j:ajax tag. It was sending a second request, and the messages were cleared. This works:

<h:form id="uploadForm" enctype="multipart/form-data">
    <h:message id="message" showDetail="true" for="uploader" errorClass="error" warnClass="warning" infoClass="info" fatalClass="fatal"/>
    <rich:fileUpload id="uploader"
             fileUploadListener="#{itemController.uploadListener}"
             maxFilesQuantity="1"
             acceptedTypes="csv"
             render="items, message" />
</h:form>
