Unexpected error using fileUpload component

liukvar · 17 Dec 2014, 17:06

Hi
I am using PrimeFaces 5.1.6 (Elite)

When using fileUpload component file object (org.primefaces.model.UploadedFile) is always null.

I have created a single page like this http://www.primefaces.org/showcase/mobi ... Page.xhtml

Removing the tag <f:view renderKitId="PRIMEFACES_MOBILE" /> everything work properly.

In web.xml I have:

Code: Select all

<context-param>
		<param-name>primefaces.UPLOADER</param-name>
		<param-value>native</param-value>
	</context-param>

Using Firebug I noticed this difference:

page with <f:view renderKitId="PRIMEFACES_MOBILE" /> => file always null
Request Header from Upload Stream
Content-Length 1586786
Content-Type multipart/form-data; boundary=---------------------------20773183922614

page without <f:view renderKitId="PRIMEFACES_MOBILE" /> => file org.primefaces.model.NativeUploadedFile
Request Header from Upload Stream
Content-Length 1586644
Content-Type multipart/form-data; boundary=---------------------------1506631681792

Any ideas on this?

Best regards

I'm seeing the same behaviour too running a 5.2 snapshot from a couple of days ago - I've not done the firebug checks that you have, but the UploadedFile in the backing bean is always null.

Non-mobile page using the same backing bean works no problems.

As a sanity check I reverted to PF 5.1, and the UploadedFile is populated correctly there, so this does seem to be something introduced since then.

Application server is Glassfish 4.1, using the default version of JSF that comes with that.

I have the same problem (tried with PF 5.1.8 and 5.1.1).
BTW, mode="advanced" seems not supported (almost graphically).
I checked the official documentation but nothing is wrote about PF Mobile fileUpload and about which mode is supported.
Primeface Mobile Showcase only shows a silly example with mode="simple"
I can not believe that Primefaces is so buggy.
If I delete the line:

Code: Select all

<f:view renderKitId="PRIMEFACES_MOBILE" />

the graphical result is weird but it works.

Liukvar, have you solved the problem or did you use alternatives to Primefaces?

Bye.

I resolved this issue in my application by switching to the <h:inputFile> tag as as shown below:

Code: Select all

<h:inputFile
    id="file"
    value="#{fileUpload.file}"
    required="true"
    requiredMessage="File is required."
    label="File" />
<p:commandButton
        value="Submit"
        ajax="false"
        action="#{fileUpload.upload}" />
