Error while using jsp scriptlet or expression with JSPDynpage default jsp

Question

Hi everyone,
I am getting the following error while trying to use any kind of jsp scriptlet or expression within the default jsp page that is created with JSPDynpage application:
Portal Runtime Error
An exception occurred while processing a request for :
iView : Navroz_JSPDynPage_JCo_BAPI_FLCUST.FlightCustJSP
Component Name : Navroz_JSPDynPage_JCo_BAPI_FLCUST.FlightCustJSP
Error occurs during the rendering of jsp component.
Exception id: 08:50_05/10/06_0032_17543050
See the details for the exception ID in the log file
For example if I try to use even simple syntax like:
<% if(true) { %>
display htmlb tableviewcomponent
<% } %>
or
<hbj:tableView
     id="myTableView"
     model="flightCustomer.model"
     design="ALTERNATING"
     headerVisible="true"
     footerVisible="true"
     fillUpEmptyRows="true"
     navigationMode="BYLINE"
     selectionMode="SINGLESELECT"
     headerText="Flight Customer List"
     onNavigate="Navigate"
     visibleFirstRow="<%=flightCustomer.getVisibleFirstRow()%>"
     visibleRowCount="5"
     rowCount="16"
     width="500 px"
     />
here also the <%=flightCustomer.getVisibleFirstRow()%> line gives the above mentioned error. If I remove such scriptlets or expression then it works fine.
What could be the problem. Are jsp scriptlets or expressions incompatible with portal applications?
