This was a problem when using a brain as a ZODB component because an old
version of the class and module was kept as the _v_ attribute. The problem was
when the components where reseted

Before this change, an unconfigured Web Section would match all
available documents, which can be surprising (security would still apply,
of course).

Remove depth limitations on domain generator.
Make ListField item list generator present resource hierarchically (either
through indentation or through relative title-based paths, depending on
preference).
Also, share a bit of code between both.

We generating url to see list of task reports in task report module, we have to use
left joins to find out task reports with no items

Former behaviour for entry ('foo', None) was:
  <option value="value">foo</option>
With this change, it becomes:
  <option disabled="disabled">foo</option>
which was not possible to render before.

effective_date, when defined, prevents a document from being visible even
if it is in the correct workflow state.
Note that this is orthogonal with workflow states: a document which must
not be visible should not be in a workflow state which makes it visible to
begin with. effective_date only affects website-style document listing and
lookup.

As this means sorting had no effect, drop sorting on versions: versions
are arbitrary strings which can have any evolution scheme, so do not try
to guess what is more recent than something else.

Also, make effective date visible and editable on relevant document views
lacking it.
Add a test.

Specifically, system must not compare version to decide which is older, and
does not. So remove noise from test, and reword docstring.

The duplicated getBrain/getObject code in Shared.DC.ZRDB.DA only exists with
some versions of Zope or Products.ZSQLMethods

reload(), which should be called only for filesystem tests, was called for
ZODB Components. So on the first execution, sys.modules was updated with a new
instance of the module whereas the module in erp5.component.test stayed the
same. On the second execution, reload() failed it checks whether
sys.modules[MODULE] == erp5.component.test.MODULE.

* date attribute is converted to timezone only when attribute is accessed (and not in __init__ anymore). Some code that needs performance may be able to use date_utc attribute wich is the date as UTC
* debit, credit, debit_price and credit_price uses "is_cancellation" column instead of getObject().isCancellationAmount()

* Ctrl+S to save
* Ctrl+space to autocomplete
* unsaved changes warnings

erp5_mysql_innodb_catalog: add related keys child_aggregate_relative_url and parent_journal_relative_url

This allows to use the same script for various columns. It is
particularly convenient for listbox used in reports with a list of
columns that could vary depending on data.

It happens for some objects that we don't allow the user to see them, even though
we might allows them to get some informations. Typically an object that they
should not see in a module but that could be used for some purposes.
