I need to upload multiple files, but I need to upload them all together then the "submit" button is clicked (that either ALL files are stored, or nothing).
How can I achieve this? And how can I get a list of files which I uploaded?
here is my code:
<h:form>
<p:fileUpload fileUploadListener="#{bean.moveFile}" allowTypes="/(\.|\/)(gif|jpe?g|png)$/" mode="advanced" dragDropSupport="true" multiple="true" />
<h:commandButton value="Speichern" action="#{bean.submit}" />
</h:form>
