There are some bugs lurking in the interaction between the ajax4jsf components and s:fileUpload. First and simplest, putting an a:support inside a s:fileUpload component doesn't do anything. Second, this code:
<a:form id="uploadForm" enctype="multipart/form-data">
<h:outputLabel for="file">Give us a file!</h:outputLabel>
<s:fileUpload id="file" data="#{uploadTest.inputStream}"
accept="image/jpeg,image/png"
fileName="#{uploadTest.fileName}"
contentType="#{uploadTest.contentType}" />
<h:commandButton id="save"
value="Do it"
action="#{uploadTest.upload}"/>
<a:commandButton action="#{uploadTest.upload}"
value="Do it AJAX-style" reRender="uploadForm"/>
</a:form>
does work when the h:commandButton is used, but does not work when the a:commandButton is used. When the a:commandButton is used, the InputStream is always null (not set) so it doesn't upload
It seems like s:fileUpload and ajax4jsf / richfaces don't cooperate.
Can anyone suggest a work-around? Obviously what I'm trying to do is create a form that lets someone do a partial refresh with an uploaded image.
