Help: 'JBO-26080: Error while selecting entity object' on RefreshDataSource

Question

Hi all,
The Problem:
My page throws out a JBO-26080 error on the RefreshDataSource Tag. This only happens the second time it needs to be refreshed, i.e. the second time the form is submitted to processRequest.jsp (see Background Info below). In my testing I have found that it is definately the RefreshDataSource tag.
Any help will be much appreciated.
Background Info:
I have 2 JSP's, 1 (report.jsp) that displays a table and 1 (processReport.jsp) that runs a stored procedure, implemented as a method in the Application Module, to select data for the table.
The method in the application module:
public void doCurrencyCalc()
CallableStatement st=null;
try // 1
String stmt = "BEGIN CONVERT_MONEY(?,?,?,?,?,?,?,?);END;";
int nParam = 3;
System.out.println("** SQL = " + stmt);
DBTransaction tr = getDBTransaction();
st=tr.createCallableStatement(stmt,DBTransaction.DEFAULT);
st.setString(1, getWB());
System.out.println(" > WB = " + getWB());
st.setLong(2, getKpi());
System.out.println(" > Kpi = " + getKpi());
for(int i=0; i<6; i++)
if(getWbSel(i+1)) st.setString(nParam,String.valueOf(getWbNo(i+1)));
else st.setString(nParam,null);
nParam++;
} // for i
st.executeUpdate();
System.out.println("** Calculation Complete");
} // try 1
catch(SQLException s)
throw new JboException(s);
} // catch SqlException
finally
try{if(st!=null)st.close();}
catch(SQLException s){      }
} // finally
} // end doCurrencyCalc
The processReport jsp:
<%@ taglib uri="/webapp/DataTags.tld" prefix="jbo" %>
<%@ page contentType="text/html;charset=windows-1252"%>
<%@ page import="za.org.saawu.ibs.bc4j.common.IBSbc4jModule"%>
<jbo:ApplicationModule id="IBSbc4jModule" configname="za.org.saawu.ibs.bc4j.IBSbc4jModule.IBSbc4jModuleLocal" releasemode="Stateful" /><%
IBSbc4jModule app = (IBSbc4jModule)IBSbc4jModule.useApplicationModule(true);
String strDisplay = new String(request.getParameter("btnDisplay").toString());
if(request.getParameter("KPIGroup")!="-1") {
app.setKpiGroup(new Long(request.getParameter("KPIGroup")).longValue());
if(request.getParameter("Kpi")!="-1") app.setKpi(new Long(request.getParameter("Kpi")).longValue());
else app.setKpi(0l);
String strParams[] = request.getParameterValues("wbsel");
app.resetWBSel();
if(strParams.length>0) {
for(int nCount=0; nCount<strParams.length; nCount++) {
int nWBNo = app.findWB(strParams[nCount]);
if(nWBNo>-1) app.setWBSel(nWBNo+1,true);
} // for
app.doCurrencyCalc();
} else {
session.setAttribute("info","NO_WBSEL");
} // if strParams length is 0
if(strDisplay.compareToIgnoreCase("TABLE")==0) {
session.setAttribute("info","REFRESH_TABLE");
} else if(strDisplay.compareToIgnoreCase("GRAPH")==0){
session.setAttribute("info","REFRESH_GRAPH");
} // if the request btnDisplay is TABLE
} else {
session.setAttribute("info","NO_KPIGROUP");
} // if the KPIGroup was selected
%>
<jbo:DataSource id="srcOutput" appid="IBSbc4jModule" viewobject="OutputView" />
<jbo:RefreshDataSource datasource="srcOutput" />
<jsp:forward page="report.jsp" />
<jbo:ReleasePageResources />
The report jsp is a form that has some input selections and the DataTable tag

Michael:
'JBO-26080' means that something was wrong with the SQL statement issued to get the data for an entity object.
You need the detail exception stack trace to see what went wrong at the JDBC level. Take a look to see if the exception reported on your browser has detail exception info on it.
If not, you should run your middle tier app with diagnostic turned on. This will output lots of diag info on console and you should get the detail exception in it. Please take a look at the detail exception. If you can't make sense out of the exception, post it to this thread.
To turn on diagnostic, you need to specify
-Djbo.debugoutput=console
as one of the JVM switches.
If you're invoking your app (middle-tier app) from command line,
include -Djbo.debugoutput=console as in
java.exe -Djbo.debugoutput=console ...
If you're running your app from within JDev:
1. Select the project.
2. Do right mouse click and select "Project Settings..."
3. On the Settings dialog, select Configurations/Runner.
4. In the righthand side pane, you should see a textbox for "Java
Options". Please add the following JVM switch:
-Djbo.debugoutput=console
Then, rerun. The run command should include
-Djbo.debugoutput=console as in
"D:\JDev9i\jdk\bin\javaw.exe" -Djbo.debugoutput=console -classpath ...
Thanks.
