BC4J FindByKey problem

Question

I have a uiXML page where the user is entering data into a form, based on a entity object. A new row is created and the row key is set as a paeg property. In my java class (called from an event handler) I am trying to locate the newly created (and committed) row based on that key. The error I am receiving is :
oracle.jbo.DMLException: JBO-26080: Error while selecting entity for Screening
java.sql.SQLException: ORA-01410: invalid ROWID
The handler on my uiXML page looks like this
<event name="apply" >
<bc4j:chaining>
<bc4j:findRootAppModule name="ScreeningView1AppModule" >
    <bc4j:findViewObject name="ScreeningView1" >
        <bc4j:findRow name="CreateScreeningView1"  >
          <bc4j:setPageProperty name="key" >
            <bc4j:stringKey/>
          </bc4j:setPageProperty>
          <bc4j:setPageProperty name="screeningSite">
            <bc4j:parameter name="Site"/>
          </bc4j:setPageProperty>
          <bc4j:setAttribute name="Site"/>
          <bc4j:setAttribute name="Dob"/>
          <bc4j:setAttribute name="SjPositive"/>
          <bc4j:setAttribute name="SjSurvey"/>
          <bc4j:setAttribute name="Sj3Criteria"/>       
          <bc4j:setAttribute name="ConsentForm"/>       
          <bc4j:setAttribute name="ExcludedDiseases"/>               
          <bc4j:setAttribute name="ExcludedDisorders"/>               
          <bc4j:setAttribute name="SerumCreatinine"/>                       
          <bc4j:setAttribute name="HadCancer"/>                       
          <bc4j:setAttribute name="BirthControlOk"/>                       
          <bc4j:setAttribute name="OtherTrials"/>                       
          <bc4j:insertRow/>
          <bc4j:commit/>   
        </bc4j:findRow>
    </bc4j:findViewObject>
  </bc4j:findRootAppModule>
  <method class="jivrDemoPackage.Screening" method="createTxn"/>
  </bc4j:chaining>
</event>and my java code in Screening.createTxn is
    ViewObject vo = ServletBindingUtils.getViewObject(context); 
    String pageKey = page.getProperty("key");
    Msg.println("Key page property " + pageKey);
    Key key = new Key(pageKey, vo.getAttributeDefs());  
    Row[] viewRows = vo.findByKey(key,1);
    Row viewRow = viewRows[0];The value printed out for pageKey looks like this "0001000000063837353830380000000A000000F6D14CE6B9
" but straight after this, the error message given at the top of this posting is displayed. Any idea what I'm doing wrong ?
Thanks,

Answer 1

I have also tried using "usesCurrency=true" in the bc4j registry def and then using ViewObject.getCurrentRow() in my Java and was not working. I realised then that my method call was outisde the view object scope so once I moved it back in (just before the </bc4j:findViewObject> tag) it worked !. However I could still not get the findByKey to work - the same error message was displayed ??
Thanks
