Create Table:
Test_Table1 with primary key testId1, testId2
Test_Table2 with primary key testId3, testId4 & testid5 as normal column.

Create View:
Test_View
select * from Test_Table1 , Test_Table2;

Hibernate Mapping for Test_View:
<class name="Testview"
table="Test_View" >
<composite-id name="testviewID" class="TestviewID">
<key-property name="testId1" type="java.lang.String">
<column name="testId1" length="20" />
</key-property>
<key-property name="testId2" type="java.lang.String">
<column length="16" name="testId2" />
</key-property>
<key-property name="cusipIssueNumber" type="java.lang.String">
<column length="12" name="CUSIP_ISSUE_NUMBER" />
</key-property>
<key-property name="testId3" type="java.lang.String">
<column length="1" name="testId3" />
</key-property>
<key-property name="testId4" type="java.lang.String">
<column name="testId4" length="10" />
</key-property>
<key-property name="testId5" type="java.lang.Long">
<column name="testId5" length="10" />
</key-property>
</composite-id>

Now suppose for one of the record in DB the testId5 is null then using org.hibernate.ScrollableResults to get the data from view.
scrollableResults = criteria.scroll(ScrollMode.FORWARD_ONLY);
returning null element in the result list.
Actual:
Hibernate is loading the row with null object in between the list returned as shown below:
[testObj1, testobj2, null, testobj3]
Expected:
HIbernate should ignore that row or it should throw as error.
Let me know if need more information on this.
