  2. Drag a Repeat Until activity into the designer.
  3. Click the Repeat Until activity to display its property fields in the Property Inspector or double-click the Repeat Until activity.

    For information about editing activities in the Property Inspector, see How to Edit BPEL Activities in the Property Inspector.
