TamperedWithPartContext jQuery fileupload

[Arve Voldsund]

Hi,

I have an upload that is working pretty fine, but the update method (which is copied from the sgagility example and is working in other controllers) complains like this:

Dryml::PartContext::TamperedWithPartContext (Dryml::PartContext::TamperedWithPartContext):

I've tried renaming because google returned an issue with long context names, but to no avail. I'm stuck on this one, and it would be fine to get the update method to complete the ajax response and do the redirect :)

Anyone had this before?

The most common reason for that error is that your browser has an old
version of the page in its cache. ctrl-refresh your browser and then
try the upload again. Luckily this is usually only a problem during
development.

Thanks for the suggestion. Did that, cleared history and restarted passenger but it's still the same. The upload works for single and multiple files, but the update method is stuck. More info:

'undefined' is probably not a valid part context. :)

Can you post your DRYML snippet with the part & form?

Ooops... I must have gone blind on this one.. And still is.

This is the edit-page where the upload is located:

<edit-page content-size="9">

<body: class="container-fluid"/>

  <aside:>

    <!--The photo form has to be outside of the main form-->

    <attached-prattach-form/>

    <div part="status-box" id="status-box">

      <span id="edit-status" class="alert alert-success pull-right">

    

      </span>

    </div>

  </aside:>

    

  <delete-button: replace/>

   <prepend-content-header:>

    

  </prepend-content-header:>

  

  <form: update="status-box" no-spinner="true">

    <field-list: replace>

Found it. I changed the part from image to prattach and the erb wants image....

<div class="span9">

          <attached-prattach part="prattach"/>

        </div>

Sorry to bother you, and thanks for your help.
