FileUpload (onsizerejected) Richfaces - WebFlow

[migelct]

Hello,

Richfaces 3.3.3 - WebFlow 2.2.0

I'm using the fileupload component of RichFaces, it works properly in local but when it's deployed in a 'pre-production' server it has one error (the other functionalities of the component are working well).

ERROR: If the file is bigger of the maximum allowed size is displaying Transfer error occurred and it's not throwing the javascript event onsizerejected.

Do you have any idea about what can be the problem? Thanks in advance.

Jsf page:

<rich:fileUpload id="upload" fileUploadListener="#{messageViewTO.uploadAttachment}"
                            listWidth="400"  listHeight="auto" addControlLabel="#{msgs['view.browse']}" rendered="#{messageViewTO.editable}"
                            maxFilesQuantity="10" immediateUpload="true" autoclear="true" stopButtonClass="stopButton" entryStopLabelClass="stopButton">
                            <a4j:support event="onupload" action="#{messageViewTO.displayUploadNotification}" />      
                            <a4j:support event="onuploadcomplete" reRender="info" />  
                            <a4j:support event="onsizerejected" reRender="upload" action="#{messageViewTO.displayMaxSizeError}" />   
            </rich:fileUpload> 

web.xml:

Another importan thing is that in the local enviorement we have only Tomcat and in the 'Pre-Production Enviorement' we have Apache connected to Tomcat.
