Hi,

>From your point of view, this is considered as low, I understand well, because this sparse fields are not used in OpenERP actually.
But this is now a feature of the framework and this bug totally prevents an usage of these fields. We use it as instance in magentoerpconnect.

I provided the fix, a branch and shown you how to reproduce the issue with a screencast.
If I'm not wrong, this is a very straightforward and little error and fix.
Moreover, if my fix were wrong (but I don't think so), nobody except the Magentoerpconnect modules editors (so mainly Akretion and us on trunk) would be impacted, but anyway it does not work at the moment...

So if someone can apply my patch, I would be grateful.

Thanks & have a nice day
Guewen

Title:
  [trunk] Sparse field : AttributeError: 'sparse' object has no
  attribute 'relation'

Status in OpenERP Server:
  Confirmed

Bug description:
  Hello,

  It concerns the sparse field recently introduced in the trunk version.
  I made a merge proposal here : https://code.launchpad.net/~c2c/openobject-server/trunk-server-sparse-fix-gbr/+merge/87595

  An error may occur when multi sparse field are stored in a serialized field and at least one is a m2o, m2m or o2m.
  The current code call self.relation, but as we loop on field_names, it should be obj._columns[field_name].relation
