How to access biz data of process instances in workspace at any time in 11g

Question

Hi,
We are using Oracle BPM Suite 11g.
Our users want to be able to check and search the business data associated with the process instance at any time (i.e. even after the instance is completed. And the business data should be included in the task list or search result list in the BPM workspace.
I am new to Oracle BPM 11g. Please help. For the data to be displayed in the workspace, should I define them as “Process Data Objects”?
Regarding to how to display the data, I find something about Flexfield. But the Oracle document says the Flexfield is for the data that saved in human workflow database schema. When the process instance is completed, will the data in human workflow database for this instance be removed? Can I setup flexfield for the Process Data Objects?

Hi Ramandeep,
Apparently I am not getting the required exception.
I have a TF that outputs an Invalid Region Site when I run it and the when I run it I only got the loading page image of ADF.
Looking at JDEV logs, I see an Invalid Region Site error
Here's what I did, I created a TF template with only one view in it like this.
<?xml version="1.0" encoding="windows-1252" ?>
<adfc-config xmlns="http://xmlns.oracle.com/adf/controller" version="1.2">
  <task-flow-template id="TFTemplate">
    <default-activity id="__7">errorPage</default-activity>
    <exception-handler id="__14">errorPage</exception-handler>
    <view id="errorPage">
      <page>/com/test/errorPage.jsff</page>
    </view>
    <use-page-fragments/>
  </task-flow-template>
</adfc-config>My error page as this:
<af:panelGroupLayout id="pgl1">
     <af:outputText value="Error has occurred!" id="ot2"/>
     <af:outputText value="#{pageFlowScope.MyErrorHandler.stacktrace}" id="ot1"/>
</af:panelGroupLayout>...and my bean.
public class MyErrorHandler
  public String getStacktrace() { 
    ControllerContext context = ControllerContext.getInstance();
    ViewPortContext currentRootViewPort = context.getCurrentRootViewPort();
    Exception exceptionData = currentRootViewPort.getExceptionData();
    if (currentRootViewPort.isExceptionPresent())
      if(exceptionData!=null)
        return exceptionData.getMessage();
    return null;
  }But exception data still returns null.
I exactly wanted to show this invalid region site but it seems I cannot catch it.
Any idea why?
