fileUpload and ajaxSingle

[ratoo]

hello!

I can not upload a text file and return it into the form.

<rich:fileUpload fileUploadListener="#{MyForm.upload}">
 <a4j:support event="onuploadcomplete" ajaxSingle="true" reRender="myTextArea"/>
</rich:fileUpload>

I catch the file into upload(UploadEvent event) method and put it into the String, but then this string is overwritten by the textarea itself (calling setMyTextArea())

I tried to use "region" - no luck! :-(

Any idea?

Thank you

I'm not sure this helps, but it sounds like the problem that is described in the rich-faces sample: 'local-value-demo'

Exactly! haven't seen it.
The only problem is that "region" doesn't work:

<a4j:region>
 <rich:fileUpload
 immediate="true"
 fileUploadListener="#{AnySequenceForm.upload}"
 uploadData="#{AnySequenceForm.files}"
 maxFilesQuantity="1"
 immediateUpload="true"
 autoclear="true"
 listHeight="30px"
 fileEntryControlClass="UploaderEntryControlClass"
 uploadListClass="UploaderListClass">
 <a4j:support
 event="onuploadcomplete"
 ajaxSingle="true"
 reRender="the_sequence_panel"/>
 </rich:fileUpload>
</a4j:region>

As far as I understand "region" limits the information to be send to the server by ajax request so my "BAD" textarea shouldn't be updated... but it is.

Should I submit a bug?

fileUpload submits all the form. To avoid this problem you could:

1) Split forms for upload and output
2) Split value bindings for uploaded file and text area.
a)Bind textarea to some bean property and upload file to the other one.
b) in ajaxSingle request from your support - set the textArea property value to the value of the second propety
