Jsp.parse.JspParseException

Question

Hi,
I am using JDeveloper 3.2 to develop a develop a JSP application. I trying to get records to display on a custom screen layout.
The first record is displayed. However, I get the following error message when I use the Navigation Bar to go to the next record:
oracle.jsp.parse.JspParseException: Line # 41, Error: Tag attempted to define a bean which already exists: RowViewer
Could you please let me know what I am doing wrong and how I could rectify the error? My code is as follows:
<jsp:useBean class="oracle.jbo.html.databeans.NavigatorBar" id="nb" scope="request" >
<%
nb.setTargetUrl("EMPAppView.jsp");
nb.initialize(application,session, request,response,out,"EMPApp_EMPBC_EMPAppModule.EMPView1");
String sImageBase = "/webapp/images";
nb.setImageDir(sImageBase);
nb.addButton(nb.NAVIGATE_FINDFORM , "EMPView_Query.jsp");
nb.addButton(nb.NAVIGATE_BROWSE , "EMPView_Browse.jsp");
nb.addButton(nb.NAVIGATE_INSERT , "EMPView_Insert.jsp");
nb.addButton(nb.NAVIGATE_EDIT , "EMPView_Edit.jsp");
nb.render();
%>
</jsp:useBean>
<jsp:useBean id="RowViewer" class="oracle.jbo.html.databeans.ViewCurrentRecord" scope="request">
<%
RowViewer.initialize(pageContext, "EMPApp_EMPBC_EMPAppModule.EMPView1");
RowViewer.setReleaseApplicationResources(true);
RowViewer.getRowSet().next();
%>
</jsp:useBean>
<pre>
<table>
<tr>
<td>
<%= RowViewer.getRowSet().getCurrentRow().getAttribute("EmpId")%>
</td>
</tr>
<td>
</td>
</tr>
</tr>
</table>
</pre>
</body>
</html>
</pre>
</BODY>
</HTML>

Since you're using JDeveloper 3.2, I suggest you use data tags to display a custom screen layout - they'll do a much better job of this.
Thanks
