Richface fileupload ajax event uploadcomplete not called if rendered attribute is used

[mweiss]

Hi,

I'm using richface 4.5.17 final with Payara (GlassFish) 4.1.1 and facing the following problem:

If I include a rendered attribute in the fileupload component the uploadcomplete event is no longer called.

Example where event is not called:

<rich:fileUpload 
      fileUploadListener="#{richFileUploadBean.popupFileUploadListener}"
      id="fileUpload" maxFilesQuantity="1"
      maxRequestSize="5000000"
      rendered="#{!richFileUploadBean.popupUploadFinished}"
     >
     <a4j:ajax event="uploadcomplete" oncomplete="alert('fileupload completed')" />
</rich:fileUpload>

In this case I try to set the boolean popupUploadFinished to true in the listener once the file is uploaded and hide the fileUpload afterwards. The listener is called.

Working example:

<rich:fileUpload 
      fileUploadListener="#{richFileUploadBean.popupFileUploadListener}"
      id="fileUpload" maxFilesQuantity="1"
      maxRequestSize="5000000"

     >
     <a4j:ajax event="uploadcomplete" oncomplete="alert('fileupload completed')" />
</rich:fileUpload>

By removing the rendered attribute everything works fine and the alert is shown. The listener is still called.

Even a workaround with a panelGroup surrounding the fileUpload where the rendered attribute is defined leads to the same behavior.

Any ideas?

Thanks

Markus

Non-rendered components do not trigger events, the fileupload has to still be rendered if you the use the uploadcomplete. Also a4j:ajax sends another request to the server, if you just want to trigger some client-side code you don't need that.
