I try to do a file upload in primefaces with PF 5.1 and OmniFaces version 1.7.
My .xhtml code:
<h:form id="fileImportForm" styleClass="prepend-top"
prependId="false">
<div style='margin-bottom:10px'>
<h:outputLabel value="#{msg.file_import_msg}"/>
</div>
<p:fileUpload id="fileImport" fileUploadListener="#{fileImport.handleFileUpload}"
mode="advanced"
update="messages"
multiple="true"
label="#{msg.file_import_choose_label}"
uploadLabel="#{msg.file_import_upload_label}"
cancelLabel="#{msg.file_import_cancel_label}"
/>
<p:growl id="messages" showDetail="true"/>
</h:form>
My backing bean:
package test.boundary;
import javax.inject.Named;
import org.primefaces.event.FileUploadEvent;
import com.haslerrail.aura.common.exception.SystemException;
/**
* BackingBean for <code>fileImport.xhtml</code> page.
*
*/
@Named
public class FileImport implements java.io.Serializable {
private static final long serialVersionUID = 1L;
public void handleFileUpload(final FileUploadEvent event) throws SystemException, InterruptedException {
if (event == null || event.getFile() == null || event.getFile().getSize() == 0) {
System.out.println("No file");
}
System.out.println(event.getFile().getFileName());
Thread.sleep(500); // wait a little to force the exception!
}
}
The problem is, when my handleFileUpload function takes a little bit longer to parse the uploaded file (Thread.sleep(500), it throws an exception! The exception only occurs when I'm uploading more than one file at the same time.
The exception:

For me it looks like an error in PF 5.1! Any other ideas?
