Wes Thanks for your quick response. You gave me the clue I needed!. OK, so I had this statements in my jsp:
<td><ww:radio theme="simple" name="responses[%{questionNo}].value" list="%{#{5:''}}" /></td> which produced the following error message: org.apache.jasper.JasperException: /WEB-INF/pages/assessment/questions.jsp(33,20) PWC6038: "%{#{5:''}}" contains invalid expression(s): javax.el.ELException: Error Parsing: %{#{5:''}} I escaped the #{ as follows: <td><ww:radio theme="simple" name="responses[%{questionNo}].value" list="%{\#{5:''}}" /></td> but that gave me the error: tag 'radio', field 'list', name 'responses[1].value': The requested list key '%{\#{5:''}}' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location] so I changed it to this: <td><ww:radio theme="simple" name="responses[%{questionNo}].value" list="[EMAIL PROTECTED]@{5:''}}" /></td> and that gave me: tag 'radio', field 'list', name 'responses[1].value': The requested list key '[EMAIL PROTECTED]@{5:''}}' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location] so another change: <td><ww:radio theme="simple" name="responses[%{questionNo}].value" list="[EMAIL PROTECTED]@{5:''}" /></td> which still gives me: tag 'radio', field 'list', name 'responses[1].value': The requested list key '[EMAIL PROTECTED]@{5:''}' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location] so yet another change: <td><ww:radio theme="simple" name="responses[%{questionNo}].value" list="[EMAIL PROTECTED]@{5:''}}" /></td> which worked as does: <td><ww:radio theme="simple" name="responses[%{questionNo}].value" list="[EMAIL PROTECTED]@{5:''}" /></td> which also works. Just to amke sure, I checked that the last change is backward compatible with Tomcat 5.5.23 (and therefore JSP 2.0).
