   The proper way is always wait for notification message after click proceed, since the spinning icon can flick between before the post and reload the page (probably because notifySubmitted).

   This tiny flickering can cause confuse the wait_for_content macro since it is called too soon.

   Mostly to translate Open allocation state (causing test to fail)

   The selenium dont assert well with \n and code, so play safe and just assert line by line.

   This ensure data is saved before render a new form.

  This strips the form rendering from the parameter editor, and placing it as a stand alone editor (separated gadget).

   This allow us following the same API use other gadgets as parameter editors.

the shebang of its software release's bin/buildout. But when the path

`exec <executable>`.

Improve hateoas support to show shared instances.

It turns out that ERP5 returns
```
'form_id': {
  'type': 'StringField',
  'key': 'form_id',
  'default': 'InstanceTree_viewAsHateoas',
},
```
for the `form_id` in hateoas, so adapt the proxy to do the same.

Currently hateoas support in proxy only lists non-shared instances,
so this always says that the instances are not shared.
