This stopped working when the signature of Message.__init__ changed in
06aee0c2 (CMFActivity.ActivityTool: Use uid for identity check instead of
oid., 2019-09-17)

"Access Tool" sounds like a tool to access, but this setting is about
giving access to ERP5 tools from the module list.

we have such error:
....
if context.getValidationState() in ["draft", "deleted", "cancelled", "archived"]:
  Module Products.ERP5Type.Accessor.WorkflowState, line 60, in __call__
    return wf._getWorkflowStateOf(instance, id_only=1)
  Module Products.ERP5Type.Core.Workflow, line 609, in _getWorkflowStateOf
    state_id = 'state_' + status.get(self.getStateVariable(), None)
TypeError: cannot concatenate 'str' and 'NoneType' objects

This stopped working long time ago, probably with slapos commit aa102f28f
(erp5testnode: use newer shellinabox, with a caddy frontend, 2018-09-21)

Web Site/Section were still indexable when rendering in xhtml style.

using parallel list fields cause HTML to be very big and is not good

This can sometimes be useful during development

ERP5ReportTestCase also import ERP5TypeTestCase, so if we reload it it
patches again getRequest to a function calling itself and causing

If ignore_layout=1 is present in url query, static web section show the default view so user can modify properties

But for url like
https://erp5/web_site_module/static_web_site/web_page_module/111?ignore_layout:int=1&portal_skin=Slide...
static web section should do redirection instead of showing the default view

It's difficult to distinguish if it should do redirection or show the
default view for all kinds of url

To make it simple, if portal_skin is present in url query, static web
section will do redirection event if ignore_layout is present

Double translation happened when:

- For sql_catalog.isValidColumn(name)
- When search_columns is empty
- When selection_sort_order and sort_columns are empty

So delaying translation on column titles until *_column_list are finalised.

Before this fix, double translation on Sale Order title was happened every time
displaying a Sale Order Line, for example.
