rich:fileUpload randomly fails with "Transfer failed" error - jsf

Question

I am using <rich:fileUpload> of RichFaces 3.3.3 Final. When I upload some Excel files in Chrome browser, then it sometimes shows the "Transfer failed" error message as in below screenshot:
Sample Code,
<rich:fileUpload id="fileUpload" addControlLabel="#{bundle.browse}"
allowFlash="#{not TestFileUpload.allow}"
fileUploadListener="#{TestFileUpload.fileUploadListener}"
maxFilesQuantity="10"
autoclear="false"
listHeight="135px;"
uploadControlLabel="#{bundle.upload}"
progressLabel="#{bundle.progress}"
sizeErrorLabel="#{bundle.sizeError}"
noDuplicate="true"
style="width: 100%; height: 135px;">
<a4j:support event="onuploadcomplete"
onbeforedomupdate=""
action="#{TestFileUpload.validateExcel}"
reRender="validationDetailPanelId, messageId"
focus="cancelId"/>
</rich:fileUpload>

The file is also not being uploaded to the server. How is this caused and how can I solve it?

Answer 1

i have the same problem since one of the lastest update of Chrome.
Chrome version : 36
The fileUploadListener method in the bean is called twice when you click on the upload button.
The debug mode reveals that The second time, the file is lost.
I bypassed the problem like that :
public void fileUploadListener(UploadEvent event) {
if(!event.getUploadItem().getFileName().equalsIgnoreCase("")){
//code here
}
}

Answer 2

First make your bean session scope then in web.xml change boolean attribute of createTempFiles to false instead of true just as below:
<init-param>
<param-name>createTempFiles</param-name>
<param-value>false</param-value>
</init-param>
