Question

page: JSF Based Human Task
<af:table value="#{bindings.AppointmentItem.collectionModel}"
var="row"
rows="#{bindings.AppointmentItem.rangeSize}"
emptyText="#{bindings.AppointmentItem.viewable ? 'No data to display.' : 'Access Denied.'}"
fetchSize="#{bindings.AppointmentItem.rangeSize}"
rowBandingInterval="0" id="t3">
</af:table>
java class :
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
DCBindingContainer dcbc = (DCBindingContainer) bindings;
DCIteratorBinding EmpViewIterator = dcbc.findIteratorBinding("AppointmentItemIterator");
Row rw = EmpViewIterator.getViewObject().createRow();
in run time EmpViewIterator null
I tested it table related DB it worked successfully
but when test related PBEL return null.
can suggest?

Answer 1

If DCIteratorBinding EmpViewIterator = dcbc.findIteratorBinding("AppointmentItemIterator");returns null you probably have spelled the iterator name wrong. Open the bindings tab of the page with your table on and select the iterator, click the pencil to edit the Iterator and copy the name from it with ctrl-c. Go to your bean and paste the name there.
If you can't find a misspelling you can check the DCBindingContainter for all iterator bindings using ArrayList list = dcbc.getAllIterBindingList();The list contains all iterators known by the binding container.
