[jboss-user] [JBoss Seam] - s:fileUpload doesn't preserve pending value after immediate

[tynor]

Seam 2.0.0.CR1

I have a form containing several h:inputText's, a s:fileUpload and an h:commandButton that is used to add an item to a server-side Set, which is then used to draw a dataTable on the facelet.  (I'm in a manually flushed transaction:

  | @Begin(flushMode=FlushModeType.MANUAL, join=true) 
  | 

I use this sort of button on several forms without any trouble, but I'm having problems when there is an s:fileUpload control on the form -- when the button action fires and the screen refreshes, all the other controls (select boxes, text inputs, etc.) preserve their as-yet-unpersisted values, but the filename selected by the file upload control is cleared.

Is this a bug in s:fileUpload? Can I workaround somehow?


  | <s:decorate id="txtDecoration" template="/WEB-INF/facelets/templates/edit.xhtml">
  |    <ui:define name="label">Text</ui:define>
  |    <h:inputText id="txt" value="#{myHome.instance.txt}"/>
  | </s:decorate>
  | <s:decorate id="fileDecoration" template="/WEB-INF/facelets/templates/edit.xhtml">

  |    <s:fileUpload id="file" data="#{myHome.data}" required="true"
  | 	contentType="#{myHome.contentType}"
  |         fileName="#{myHome.fileName}" accept="application/pdf" />
  | </s:decorate>
  | <s:decorate id="addDecoration" template="/WEB-INF/facelets/templates/edit.xhtml">

  |        action="#{myHome.addItem}"/>
  | </s:decorate>
  | ...
