NPE - DataHelper - Sorting failed on DataTable

[vinche]

Hello,

primefaces 2.2.1
jsf-impl-2.0.3

The dataTable sort feature have a strange behavior. (I use a DataModel)
I have to filter before the sort works.
After investigating I discover that I have a null pointer exception when I try to filter a dataTable.

________

The NullPointerExecption is never logged thanks to sun.
com.sun.faces.context.PartialViewContextImpl - line 242

Code: Select all

      try {
                processComponents(viewRoot, phaseId, executeIds, ctx);
            } catch (Exception e) {
                // RELEASE_PENDING LOG EXCEPTION
            }

_________

The exception is throw by a primeFaces class.

org.primefaces.component.datatable.DataHelper line 94 95

Code: Select all

          List list = (List) table.getValue();
          Collections.sort(list, new BeanPropertyComparator(sortColumn, table.getVar(), asc));

GetValue return a null value and the Collections.sort(..) is not nullSafe.

The error is not comming after filtering because a list of item is set in the StateHelper during the process of this two features.

Code: Select all

 public void setValue(Object value) {
        setDataModel(null);
        getStateHelper().put(PropertyKeys.value, value);

    }

Currently, I have no work arround...
