it clearly shows that the the report_webkit is not used - a lot of rml
code which obviously must fail

Title:
  report_webkit incompatibility

Status in OpenERP Modules (addons):
  New

Bug description:
  in a wizard I have this code

          data = self.read(cr, uid, ids, [], context=context)[0]

          datas = {
               'ids': [],
               'model': 'account.account',
               'form': data
          }
              #'report_name': 'account_account.tree_sum',    <<<<<< webkit 
              #'report_name': 'account.account.chart.report',  <<<<<< rml
          return {
              'type': 'ir.actions.report.xml',
              'report_name': 'account_account.tree_sum',
              'datas': datas,
          }

  the webkit report (which runs perfectly from print button) produces this error when started from a wizard.
  the rml report causes no problems.
