No error in testCMFActivity and testConflictResolution.
For the only error in testInvalidationBug, see comment.

But this commit is not enough for ZODB5. The only known issue so far
is the use of newer pickle protocol, which breaks export of ZODB data
and requires non-trivial changes in our XMLExportImport/ppml code.
So for the moment, many failures in testBusinessTempate.

erp5_web_renderjs_ui_test: reproduce validation error issue and add asserts to make sure field has expected class

* Trigger focus and blur to test renderjs functions properly
* Add asserts to make sure we don't lose value after raise Invalid Date
* Cover issue that invalid class does not disappear after click to create new object Foo in relation input
* Make sure fifth_failure input has invalid class
* Cover validation error to multicheckbox, checkbox and radio fields

* change the label field to not display the error text by default
* change all html5 fields (input, select, textarea) to add a custom *invalid* class when the field is invalid
* change all html5 fields to listen to the `focus` and `blur` event (with the renderjs onEvent method)
  Then, acquire (with `declareAcquiredMethod`) and call `notifyFocus` / `notifyBlur` methods respectively.
* change the label field to handle `notifyFocus` / `notifyBlur` (with `allowPublicAcquisition`).
  Change the validation error text display state depending on the field status
* Trigger onStateChange to set invalid class. If error comes from input field, we need to change state locally to set invalid class
* Regenerate gadget_erp5_nojqm.css from  erp5less.css using http://lesscss.org/less-preview/
* Textarea gadget should not prevent default when invalid event is triggered
* Support notifyFocus and notifyBlur in panel

Users with only view permissions in accounting should not be offered to use
the grouping reference fast inputs, because grouping transactions is a kind
of modification.

Since c4026c75 (erp5_officejs: change Notebook app editor from
iodide_master to gadget_jsmd_eval, 2020-09-23), erp5_officejs depends on
erp5_notebook, but erp5_notebook is not present in erp5 repository, it is
in erp5-bin repository.

This test works by taking an old Data.fs and running upgrader, to update
to latest code. The first thing it does is using
setupAutomaticBusinessTemplateRepository to discover folder containing
business templates repositories and enabling them. Until now it was doing
only for erp5_core (to find parts/erp5/product/ERP5/bootstrap) and for
erp5_base (to find parts/erp5/bt5/). Now we also need to do that for
erp5_notebook, to find parts/erp5-bin/bt5/

Use reveal 3.9.2
Remove font not present from reveal theme.

that would return the whole catalog

Only basic fields are supported (no gadgetfield for now).
