Primefaces fileUpload error with layoutUnit

Question

I am using a Layout structure that has centerLayout, westLayout. In center layoutUnit is used primefaces fileupload. I added filter to web.xml and fileupload required lib to WEB/INF lib.

I implemented the steps in that link : How to use PrimeFaces p:fileUpload? Listener method is never invoked or UploadedFile is null It does not work for my problem.

When layoutComplex.xhtml page is load, take following error:"/UI Layout Initialization Error. The center-pane element does not exist. The-center pane is a required element." "Error Rendering View[/layoutComplex.xhtml]: java.lang.IllegalStateException: Cannot create a session after the response has been committed"

If I write to address bar "http:....hostName/portal/dataImportingProjectCurrent.jsf" url, there is no error.

in layoutComplex.xhtml code part :

<p:layoutUnit position="center" id="centerLayout">

                <h:form id="formCenter" enctype="multipart/form-data">
                    <p:panel id="optionPanel">

                            rendered="#{menuSelection.selectedOption == menuSelection.WELCOME}">
                            <ui:include src="/welcomePage.xhtml" />

            </p:layoutUnit>

Page code that belongs primefaces fileUpload is dataImportingProjectCurrent.xhtml:

<h:body>
<h:form id="formDataImportProjectCurrent" enctype="multipart/form-data" >
    <h1>
        Project current fdasdata importinfdsa  is under construction. Coming soon...
    </h1>

    <p:fileUpload label="Seçiniz"
            fileUploadListener="#{dataImportingBean.handleFileUpload}"
            mode="advanced" auto="true" sizeLimit="1000000"
            allowTypes="/(\.|\/)(gif|jpe?g|png)$/" />

</h:form>

My bean is DataImportingBean.java :

@ManagedBean @SessionScoped public class DataImportingBean extends GenericBean implements Serializable{

private static final long serialVersionUID = 730586496885706439L;

private UploadedFile file;

@Inject
DataImportingService DataImportingService;

@Override
public GenericService<Data, Long> getService() {
    return DataImportingService;
}


@Override
public void newObject() {
    setObject(new Data());
}


public void handleFileUpload(FileUploadEvent event) {  
    FacesMessage msg = new FacesMessage("Succesful", event.getFile().getFileName() + " is uploaded.");  
    FacesContext.getCurrentInstance().addMessage(null, msg);  
    System.err.println("event.getFile().getFileName(): " + event.getFile().getFileName());
}

}

Thank you very much for response.
