[6.1]Misbehaviour on binary field (widget=image) on on_change method in one2many widget

[Husen Daudi]

Hello OpenERP,

I have added a binary field with widget='image' in one 2 many form view.
while adding image using onchange on product_id i am not getting value in binary widget using on_change.
I manage to do this using attached patch.

My patch will show the image from on_change on product but It will not getting saved.
I tried to select image manually on binary field but still its not getting saved.

The problem seems in buffer storage of one2many field.

Here is the traceback I am getting while saving the o2m record.

Hello Husen,

I did try all steps as you reported with under one2many list, widget="image" on product_id_change (product_id_change) and return the image (binary) field with latest trunk as well as stable6.1 at my end. But I have faced the problem on only 6.1.

I have attached the video for both trunk and 6.1 which is described that problem appears only on 6.1. I have faced two misbehaviour on 6.1 which is:

1) When product_id change (on_change) called binary field 's value doesn't set. But when the parent record is saved then after we can see it(binary field 's value) on one2many list.
2) When I tried to set binary field 's value manually then again I have faced similar kind of issue. After the on2many list's save this field 's values doesn't set again, and we have to save main (parent) record.

But I didn't faced any traceback at my end, I have attached the code which I applied to check this issue (which will more helpful to reproduce again). And this problem only appears on 6.1 stable version that's why I am assigning this to OPW team also it's not a blocking point, So set it as a "Low".

Please see attached video which shows more clearly.

Cheers!

Hello niv-openerp,

I arrived to this bug report following https://bugs.launchpad.net/openerp-web/+bug/1016586.

We are still experiencing the issue reported in that bug, but I see you closed this one as "invalid". Could you add a note explaining why?

Thanks
