jsf - Navigation case don't work when using h:form enctype="multipart/form-data" with f:ajax -

i'm trying create navigation case can called backing bean action or outcome link, created in faces-config.xml:

<navigation-case>     <from-outcome>curso-list</from-outcome>     <to-view-id>/core/curso/curso-list.xhtml</to-view-id>     <redirect /> </navigation-case> 

this works outcome link didn't work actions. added this:

<navigation-case>     <from-action>#{cursodetalhemb.salvar}</from-action>     <from-outcome>curso-list</from-outcome>     <to-view-id>/core/curso/curso-list.xhtml</to-view-id>     <redirect /> </navigation-case> 

but outcome didn't work too. noted problem occurs when use ajax inside form. if don't make ajax request action redirect works normally, when make ajax request action redirect don't work.

i found problem don't know how fix. form before ajax request:

<form id="j_idt60" name="j_idt60" method="post" action="/project/core/teste.xhtml" enctype="multipart/form-data"> 

my form after ajax request:

<form id="j_idt60" name="j_idt60" method="post" action="http://localhost:8080/project/core/teste.xhtml" enctype="multipart/form-data" target="jsfframeid"> <input type="hidden" name="j_idt60" value="j_idt60"> 

note "target" property, if remove navigation works fine don't know why jsf add property.
