pyPdf goes in an infinite loop when PdfFileReader are created on an empty file.

BudgetCell_view is installed by erp5_budget and this bt5 is not dependency of erp5_project. Then, if erp5_project is installed Project Cell is broken.

DeliveryCell_view is more appropriated because it is installed by erp5_trade that is a erp5_project dependency

This test was using non existant categories.

Activity is expected to be appended to message_list_dict's value already,
no need to append it to queued_activity.
In turn, this allows getting rid of _prepare_args.

_registered is already declared on TM superclass.
_p_* are only useful on subclasses of persistence.Persistent. TM is not.

This should never match, because published API does not provide access to
Message when registering it (this is intentional).
Also, this search is O(n), which makes activity creation complexity
O(n**2).

Document created with some apple tools have a custom info 'AAPL:Keywords' for
which pypdf returns a non picklable instance.

This business template contains an external method to merge multiple PDF as a
single document.

the event_workflow does no longer make a difference between incoming
and outgoing messages. Fixed creation of incoming events and add test
to check them to prevent future regression

Test should be independant and run in any order, so do not suggest a way to
force the order of tests.

there was issue with edit since getActiveProcess was called and
there was troubles with inexesting activity runtime environment
