title: Oracle BPEL eventhandling with "onEvent" activity and business event
body: <p>I'm trying to use the bpel extension for eventhandling under the soa suite 11g ps3. I'm trying to subscribe to an event from the event delivery network but I get an error.</p>
  
  <p>That's the  code:</p>
  
  <pre><code>&lt;eventHandlers&gt;
    &lt;onEvent bpelx:eventName="ns4:discountEvent" variable="discEvent" &gt;
      &lt;scope name="Scope1"&gt;
        &lt;sequence name="Sequence1"&gt;
          &lt;exit name="Exit1"/&gt;
        &lt;/sequence&gt;
      &lt;/scope&gt;
    &lt;/onEvent&gt;
  &lt;/eventHandlers&gt;
  </code></pre>
  
  <p>The compiler is giving me the following error:</p>
  
  <pre><code>Error(52): Activity &lt;bpel:onEvent&gt; must have "element", "messageType" attribute present.
  </code></pre>
  
  <p>I can't find any information on using the extension in an "onEvent" activity.</p>
  
  <p>Any help appreciated!</p>
  
  <p>Thanks, Chris</p>
