[JHS 10.1.2.2 build 32] Editting table results in NoSuchElementException

Question

Hi All,
hopefully somebody has already encountered and solved this problem.
We are using jHeadstart 10.1.2.2 build 32 and have generated our application in JSPs. But i'm running into a quite structural problem when using the editable table.
I execute the following steps:
- On a few pages we have editable tables that display one empty (new) row at the bottom.
- The tables (views) have a few mandatory columns (attributes).
- I do not fill all the required field in the empty row
- I press the commit button
The page shows the relevant message (the field is mandatory) in the screen but also dumps a NoSuchElementException in the last line.
The last line shown is the 'new' row.

     at java.lang.Thread.run(Unknown Source)I've tracked the problem down to the RangeSetWrapper class that returns a size of 6 but fills the errorBeans property with only 5 objects. When getting the 6th row (index 5) the errorBeans array throws an IndexOutOfRangeException which in turn results in the NoSuchElement exception.
Does anybody recognize this problem? Does anybody have a solution? I'm trying to hack into the RangeSetWrapper class, but am not very succesfull at the moment (Well the Exception is gone, but rows get mixed up ;-))

Ps. An extract from the JSP page:
<c:set var="RbsTalenViewNewRows" value="1" scope="request"/>
<c:forEach var="RbsTalenView" varStatus="status" items="${jhsTableBindings.RbsTalenView.rangeSet}">
   <html:hidden name="RbsTalenView" property="rowKeyStr" indexed="true"/>
   <c:set var="editMode" scope="request" value="${status.index lt bindings.TalenIterator.estimatedRowCount and bindings.TalenIterator.currentRowIndexInRange!=-1}"/>
        <tr class="altRow<c:out value="${status.index % 2 + 1 }"/>">
      <c:set var="rowKeyStr" scope="request" value="${RbsTalenView.rowKeyStr}"/>
   <td nowrap="nowrap">
      <font class="required">*</font>
      <c:if test='${RbsTalenView.TalenUnicode == null}' >
        <html:text name="RbsTalenView" property="TalenUnicode" size="10" maxlength="3" indexed="true"/>
      </c:if>
      <c:if test='${RbsTalenView.TalenUnicode != null}' >
        <html:text name="RbsTalenView" property="TalenUnicode" size="10" maxlength="3" indexed="true" disabled="true"/>
      </c:if>
   </td>
   <td nowrap="nowrap">
      <html:text name="RbsTalenView" property="TalenNaam" size="30" maxlength="64" indexed="true"/>
   </td>
   <td class="fixed">
          <jsp:include page="/common/customDeleteButton.jsp" flush="true">
            <jsp:param name="deleteEvent" value="setCurrentRowWithKey~RbsTalenView"/>
          </jsp:include>
   </td>
        </tr>
      </c:forEach>   The exception is raised during the </c:forEach> (afterBody)

Answer 1

Problem solved....
It seems we had overridden some framework method in a subclass of JhsDataAction called clearFormBeanValues(). If you don't call this method you will get the exception stack i encountered. (The comments said the forms were always cleared and it shouldn't do that when errors were encountered.... too bad, not a name ;-))
Hopefully nothing else will break now i ripped out that code ;-)
