Uploading files via AJAX using p:fileUpload with mode="advanced" - ajax

Question

I have this piece of code that upload files:
<p:dialog id="addFileDialog"
header="#{text['tasksbacking.attach.addFile']}"
widgetVar="addfile"
height="500"
width="500"
closeOnEscape="true"
resizable="false"
draggable="false"
fitViewport="true"
modal="true"
appendTo="#(body)">
<h:form enctype="multipart/form-data">
<p:fileUpload fileUploadListener="#{attachmentsComponent.handleFileUpload}"
mode="advanced"
multiple="true"
dragDropSupport="true"
allowTypes="/(\.|\/)(gif|jpe?g|png|pdf|doc|docx|txt)$/"
label="#{text['tasksbacking.addFile.choose']}"
uploadLabel="#{text['tasksbacking.addFile.upload']}"
cancelLabel="#{text['tasksbacking.addFile.cancel']}"/>
</h:form>
<p:ajax event="close"
update=":#{cc.clientId}:addFileDialog,:#{cc.clientId}:formAttachForm:attachTree,:#{cc.clientId}:formAttachForm:msgTreeAction,:#{cc.clientId}:attachContainer" listener="#{attachmentsComponent.onCloseUpload}"/>
</p:dialog>
With this code, I can upload files when I close the dialog. But I cannot execute another AJAX action, without refreshing the page. The other actions execute well when I don't upload files as the first action.
What could be the problem to execute the forward actions without refreshing the page? The enctype of the form could be the problem?

I had the same problem with enctype="multipart/form-data" form and i see this question:
File upload doesn't work with AJAX in PrimeFaces 4.0/JSF 2.2.x - javax.servlet.ServletException: The request content-type is not a multipart/form-data
And after i use this answers:

Finally, it worked!
Basically the re-render/customization of the component p:fileUpload works fine and this is one primefaces bug.
