Uncaught TypeError: Cannot read property 'length' of undefined

[Fabio Colognesi]

OpenERP version 7.0-20130206-000101

I have a search view on "ir.attachment" in which I prepared two o three filters on "create_date" field to report documents created "Today", "Yesterday" or "Last Week". This filter works well in 6.1, in 6.2 but in 7.0 raise a message :

Uncaught TypeError: Cannot read property 'length' of undefined
http://localhost:8069/web/webclient/js:3209

If I try to connect to 7.0 with GTK Client (6.1 version) my filter works fine, so it could seem a web issue.

Search View is :

    <record model="ir.ui.view" id="plm_document_search">
         <field name="name">plm.document</field>
         <field name="model">ir.attachment</field>

Many Thanks

"Uncaught TypeError: Cannot read property 'length' of undefined" is a very generic error that means that the filter did not work as expected. To verify the error enter in debug mode (About OpenERP > Activate the developer mode), debugging the javascript (in my case views.js line 776) you can verify the error object.

It seems that the relativedelta implementation in pyeval.ps does not take named arguments (could be a general problem of the javascript python evaluator implementation), my error is "TypeError: function takes exactly 19 arguments".

[gmarcon (gmarcon)]

I managed to call the relativedelta function with the Python Javascript implementation explicitly passing all the named parameters:
relativedelta(year=0, month=0, day=0, hour=0, minute=0, second=0, microsecond=0, years=0, months=1, weeks=0, days=0, hours=0, minutes=0, secondes=0, microseconds=0, weekday=0, leakdays=0, yearday=0, nlyearday=0).

But datetime.date.today() is not working (Error from the interpreter: "AttributeError: object has no attribute 'today'").

I have the feeling that the Javascript Python interpreter still needs some reworks...

Hello,

It has been fixed in lp:~openerp-dev/openerp-web/7.0-opw-591255-msh.

Thanks.

[gmarcon (gmarcon)]

The provided fix is only related to the datetime.date.today function call.

Would you also able to address the relativedelta function call? The main problems seems to be that it is not possible to call it with named arguments. Additionally the relativedelta function has several TODOs and FIXMEs in the code (including a very frightening "TODO: test this whole mess").

I am available to test the implementation in real life cases if needed.

Thank you and regards.

I do not agree that this is a duplicate of #1081044. "Uncaught TypeError: Cannot read property 'length' of undefined" is a very generic error and represents several errors on the web client.

The specific bug reported here is related to the relativedelta function call of the Javascript Python interpreter (/addons/web/static/src/js/pyeval.js ). It could be related to the more generic problem of the Javascript Python interpreter not supporting function calls with named arguments - but that does not seem the problem of #1081044 to me...

I agree with @gmarcon that it is a generic error, in my case it occurs on
