ViewCriteria with Timstamp throw ORA-01843

Question

I try to Filter Rows by Timestap with ViewCriteria:
Env:
jdev 10.1.3
table:
create table DATE_TIMSTAMP
DATE_VALUE DATE,
TIMESTAMP_VALUE TIMESTAMP(3)
EO, VO and AM created with the wizard
EO Attribute "TimestampValue" is set to TIMSTAMP
JUnitTest:
public void testTimestampViewCriteria() {
ViewObject view = fixture1.getApplicationModule().findViewObject("DateTimstampView1");
Row row = view.createRow();
Timestamp ts = new Timestamp(System.currentTimeMillis());
row.setAttribute("TimestampValue",ts);
view.insertRow(row);
fixture1.getApplicationModule().getTransaction().postChanges();
ViewCriteria vc = view.createViewCriteria();
ViewCriteriaRow vcr = vc.createViewCriteriaRow();
vcr.setAttribute("TimestampValue",ts);
vc.add(vcr);
view.applyViewCriteria(vc);
view.executeQuery();
assertNotNull(view.hasNext());
fixture1.getApplicationModule().getTransaction().rollback();
StackTrace:
oracle.jbo.SQLStmtException: JBO-27122: SQL-Fehler bei Vorbereitung der Anweisung. Anweisung: SELECT DateTimstamp.DATE_VALUE, DateTimstamp.TIMESTAMP_VALUE, DateTimstamp.ROWID FROM DATE_TIMSTAMP DateTimstamp WHERE ( ( (DateTimstamp.TIMESTAMP_VALUE = '2006-07-27 11:08:29.776') ) )

Oracle is smarter than you think .. ;)
Look at the filter condition, in the explain plan for your second query..
SQL> select *
  2  from table(dbms_xplan.display);
PLAN_TABLE_OUTPUT
Plan hash value: 1685426719
| Id  | Operation        | Name | Rows  | Cost (%CPU)| Time     |
|   0 | SELECT STATEMENT |      |     1 |     4   (0)| 00:00:01 |
|*  1 |  FILTER          |      |       |            |          |
|   2 |   FAST DUAL      |      |     1 |     2   (0)| 00:00:01 |
|   3 |   FAST DUAL      |      |     1 |     2   (0)| 00:00:01 |
Predicate Information (identified by operation id):
   1 - filter( EXISTS (SELECT 0 FROM "SYS"."DUAL" "DUAL"))
15 rows selected.Edited by: jeneesh on Jun 3, 2013 2:20 PM
IMO, It is correct.. That is how EXISTS works.It is supposed to check only the existence..
