Andreas Höhmann commented on RF-3115:
-------------------------------------

I have a complex layout and only one page for the whole application. I have a lot of "areas" (toolbar, trees, workarea, etc.) which should rerendered.
Then i have some modal-panels. These dialogs rerender some areas at "show", "hide" etc. The upload-dialog is one of these dialogs.
If i choose the file then the upload should start. After upload the dialog should close automatically. The file is allways send
to the server (my bean) but sometimes the rerendering after the upload is invalid ... the result is an empty white page with the content of "</html>"
an nothing more.

Currently i'm using the 3.2.1-SNAPSHOT and the problem is resolved (it seams to be)

> I don't know why ... but sometimes the upload returns a empty page.
> I open a modal-dialog with a fileUpload ... then select a file (immediateUpload="true") then sometimes a empty white page is the result.
> My upload-bean is allways triggered correctly (uploadListener works fine ...file is ok etc.) but it seams the rerendering works not fine allways?1
> The empty page contains only a "</html>"
> Here is my upload-Dialog:

>     </a4j:region>
> * <dialog:modalDialog> is a facelets-tag which contains a rich:modalPanel + some commons stuff (close-X, ok-button  etc.)
> * i define a region to show a separated status (nice2have)
> * the a4j:jsFunction is only a hack until rich:fileUpload supports a reRender-attribute (should i open a new bug for this?)
