Title:
  rml report seems to cache image data

Status in OpenERP Modules (addons):
  New

Bug description:
  Hi,

  I'm still running Open ERP 5, and would like to design a new rml
  template. The rml code seems just fine, but the images it contain do
  not 'loop'.

  It's a sale.order report that would show images together with product
  description. There might be several images for a given product named
  pict1-pict9, and a custom method loads their data. the situation is
  that only the first image for a given index is shown even though the
  method shows loading of all the images.

  <code>
  <section>
   [[ repeatIn(o.order_line, 'l') ]]
  <blockTable colWidths="250.0,92.0,21.0,80.0,85.0" style="T&#xE1;bl&#xE1;zat2">
    <tr>
      <td>
        <para style="P13">[[ l.name ]]</para>
      </td>
      <td>
        <para style="terp_default_Right_9">[[ formatLang(l.product_uos and l.product_uos_qty or l.product_uom_qty, digits=0) ]] </para>
      </td>
      <td>
        <para style="P13">[[ l.product_uos and l.product_uos.name or l.product_uom.name ]]</para>
      </td>
      <td>
        <para style="P9">[[ formatLang(l.price_unit, digits=0 ) ]] [[ o.pricelist_id.currency_id.name ]]</para>
      </td>
      <td>
        <para style="P9">[[ formatLang(l.price_subtotal, digits=0) ]] [[ o.pricelist_id.currency_id.name ]]</para>
      </td>
    </tr>
  </blockTable>

  <para style="P15">
    [[ l.product_id.description_sale ]]
  </para>

  <image height="260" width="520">[[ o.state=='draft' and
  get_product_attachment(1, l.product_id) or
  removeParentNode('image')]]</image>

  </section>
  <code>

  and the custom method in my report file is

  <code>
  def get_product_attachment(self, index, product):
      context = {}
      attach = self.pool.get('ir.attachment').search(self.cr, self.uid, [('res_id','=',product.id), ('name','ilike', 'pict%d' % index)])
      attach = attach and self.pool.get('ir.attachment').browse(self.cr, self.uid, attach[0]) or False
      if attach:
          print 'a', product.id, index, attach, attach.datas[:30]
          return attach.datas
      else:
          return False
  </code>
