Hello,

As Naresh explained, osv_memory are being phased out for OpenERP 6.1, which should solve a lot of issues like yours, and also makes osv_memory irrelevant in our current trunk.
We could consider patching it in the 6.0 stable branch if we found out a critical issue that would impact many customers in production, but otherwise our stable policy prevents any kind of "low priority" or "improvement" from landing there.

That said, we can help you identify the cause of your issue and determine if this could qualify as a critical issue. For that, we'll need to be able to reproduce the bug, so you will need to provide more details, and perhaps a sample module that triggers it.
For example:
- You say that it "gives an error as it uses the search method of the orm class instead of orm_memory". I'd like to run your code and see how that's possible, because it makes no sense with our usual class hierarchy. If 'mrp.component' is a subclass of 'osv.osv_memory' there is no way the osv.osv.search() method should be called, unless you're mixing both osv and osv_memory in the class tree.
- You say "of course, I've overwritten the orm_memory::search method as it would always return all the keys". Based on your traceback you're still relying on the super()._search() method, so what did you change? Perhaps there was one kind of domain that you needed to use and was not supported by osv_memory's _search() method? Can you be more specific?
- Finally, your traceback shows that the osv_memory rows you are querying do not have a cached "parent_id" column value. Can you perhaps investigate the contents of the osv_memory cache and see how that is possible?

I hope this helps...

Title:
  domain restriction in osv_memory models

Status in OpenERP Server:
  Incomplete

Bug description:
  Hi

  I have a return statement of the form:

      return {
              'name':_("Products to Process"),
              'view_mode': 'tree',
              'view_id': False,
              'view_type': 'tree',
              'res_model': 'mrp.component',
              'res_ids': new_ids,
              'type': 'ir.actions.act_window',
              'nodestroy': True,
              'target': 'new',
              'domain': '[]',
              'context': context
          }

  where mrp.component is an osv_memory object
  changing the domain restriction to something meaningful (e.g. [("parent_id", "=", None)] gives an error as it uses the search method of the orm class instead of orm_memory
  (of course, I've overwritten the orm_memory::search method as it would always return all the keys)
