Problem with FileUpload

[nishantkatoch]

Hello,

I am facing problem with FileUpload componet of JSF.


CODE:
***************************************************
<h:form id="myForm" enctype="multipart/form-data">

<t:inputFileUpload id="fileuploadfield"
value="#{uploadBean._myFile}"
storage="memory"
required="true"/>
<t:commandButton id="uploadajbut" value="upload" action="#{uploadBean.startUploadNow}" />

</h:form>
***************************************************

The above code works fine but if If put the above code in a Ajax form I am getting exception. My need is to have the file upload componet in an ajax form, but it doesn't works for me.

EXCEPTION I GET IS:

2007-04-03 22:49:04 StandardWrapperValve[Faces Servlet]: Servlet.service() for servlet Faces Servlet threw exception

PLEASE HELP.

NOTE:

- I get the above mentioned exception when I use A4J FORM and A4j CommandButton.


- I get no exception but theaction method does not get called if I use AJAX FORM and t:command Button. Just the page gets refresehed (no uploaded file and no exception)

- EVerything is fine if I use h:form and t:command button.

NOTE: My page is madeinsuch a way that this fileupload thing has to come in ajx form.
Please tell me if thereis a way out.

THANKS,
Nishant

Upload isn't available in ajax mode due to XMLHttpRequest restriction. Look to http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4033714#4033714 for workaround.
