The notification manager was removed and replaced by a notification
service. Some tests were forward ported after this change, so they need
to be updated to the new system.
The check on the event target and the barcode target is done outside
the check on barcode found. That result in a warning for each modal/form
view that is pending.
This commit do the check before doing any operations in order
to directly stop if the event target is not similiar to listening
barcode target
The barcode scanner and the quantity listener do not use
the same proccess although they act for the same operation.
(For example the quantity listener trigger onchange server side
while the barcode scanner not if 'notifychange' key on the
active_barcode is set to False)
Since quantity listener is based on candidate we could directly
call the _barcodeSelectedCandidate method in order to have a common
behavior and code.
There is a subtle issue happening in tests when we override a widget
property for the duration of the test and try to restore the initial state at
the end by rewriting on the property. It actually changes the widget, by
having a function bound to the sub widget prototype instead of its ancestor.
This in turns can cause weird interactions with the class system.
We introduced a proper way to temporarily patch a class/widget by adding
a method in testUtils to do exactly that. This commit simply uses that
method to prevent unwanted interactions in barcode tests
Resetting the key 'test_barcode_handler' to its value before the
test was technically the best solution, as a test should leave the
environment unchanged. However, in this case, the widget is
undefined (there is obviously no 'test_barcode_handler').
Whereas this should not be a problem (the fields in the registry
are supposed to be accessed using get(), and the presence of a
key mapping undefined is equivalent to the absence of the key in
this case), this breaks a test in Studio if the latter one is
executed after the barcode test. This is because Studio browses the
map of the field registry to access each field's prototype. When it
encounters an undefined value, it crashes.
The barcode mechanism is supposed to handle commands PAGER-FIRST
(go to first record referenced in the pager) and PAGER-LAST (go
to last record). Before this rev., it wasn't the case.
We needed to add an option 'notifyChange' to the updateState
function of the pager, to ensure that the form is correctly
reloaded when the pager cursor is manually set (by the barcode
handler) on the first or last element.
The barcode mechanism is optimized to (in certain conditions),
directly increment the quantity of a numerical field inside an
x2many, without performing any RPC, and then re-rendering the
x2many to display the new value.
Before this rev., it seemed to work fine, but when the view was
saved, those changes of quantity were lost. This was because the
changes weren't correctly notified to the model (the quantity
field being inside an x2many, the correct update command for the
x2many should be generated).
When a barcode field with widget="barcode_handler" is in a form
view, an onchange RPC should be done each time a barcode is
scanned.
Before this rev., it worked by chance because the views using it
don't define a 'pack_operation_product_ids' field.
Anyway, this widget is meant to be generic, so it shouldn't
hardcode a fieldname.
Before this rev. a warning was displayed when a barcode mapping an
invisible button was scanned. It shouldn't, for the following
reason. In the stock.picking form view, two buttons with
barcode_trigger='validate' are in the page ('Start Inventory' and
'Validate'), and there is always at least one of them that is
invisible. So when scanning the 'validate' barcode, we don't want
a warning to be displayed, as there is potentially another button
that is able to handle the request.
When scanning a command barcode, the view shouldn't be redrawn
after the operation corresponding to the command is executed,
for two reasons: first, it is useless as the view has already
been reloaded, and second, it may cause issues if it has been
destroyed meanwhile.
For example, when scanning barcode O-CMD.MAIN-MENU from a
picking form view: a do_action is performed to go back to the
main barcode client action (so the current form view is destroyed),
but an handler tried to redrawn the destroyed form view, which
produced a crash because the session was required by Date fields,
and it couldn't be provided (there were no more parent listening
to provide it).
When a keypress event is triggered in a 'field_float_scannable'
widget, the event is first catched by the barcodes mechanism, and
then manually re-triggered. However, the way it was done implied
that the environment was notified of each keypress event, so if
there was an onchange on that particular field, an onchange RPC
was done at each keypress.
Moreover, the focus was lost at each keypress as well.
Since the new views, most of the barcodes feature was
broken. This commit re-enables the support of commands like
'edit', 'save', 'cancel', 'previous' and 'next'.
Also changed javascript event handler to jquery event handler to
make barcodes testable in phantomjs.
