Inconsistent Update error: JBO: 25014. Help Needed from Jdev team

Question

Hi,
***Please help me in solving this issue. urgent!!!. Thanks.***
I need to know how can i Update after i browse throw a rowset
and set the row attributes. Simple posting the changes and
commit is giving me following error.
I am getting JBO:25014 when i try to update a detail table for
selected number of rows.
I have a JSP page which allows the user to select either at
master level or detail level using Radio Button and
2 Text fields, one for date and other for comments at master
level. This will appear mandatorily.
In detail level, Number of rows which will be dynamically
populated. If this level is selected, and say 5 lines are
displayed, I will be having 5 text fields for dates and 5 text
fields for comments. Upon submit, I pass these text fields
values as params and receive in JSP page as String arrays in a
seperate validation page .
At the database end, I have Order Master table and Lines detail
table.
For some records in Order table, I am able to update records in
both the tables. But for certain records in Order table, I am
unable to update the detail table and throws me a JBO:25014
error: : Another user has changed the row with primary key
oracle.jbo.Key
This record is very similar to other records and i am unable to
update this record from sql*plus.
In the validation Page, where i receive the parameters, I use
View objects for Orders and Details, executeQuery for selected
Order. Then I use Row Iterator for each of the view objects, in
between the row iterator tags, I set the row attributes with the
individual lines values if Libe level is selected or the common
header date and comments value to all lines.
Then i post changes and commit.
The code is below for the way I update lines records.
<jbo:DataSource id="ds"
appid="LivePoheaders.LivePoheadersAppModule"
viewobject="MyPOLinesView"/>
<jbo:RowsetIterate datasource="ds" >
<%
//trying to get a row object
rowln = ds.getRowSet().getCurrentRow();
// formatting my date input to a valid string
lnDateStr = PohdrFcastYear+"-"+PohdrFcastMon+"-"+PohdrFcastDay;
out.println(PohdrComments);
out.println("Header date" + lnDateStr);
formatter.applyPattern("yyyy-MMM-dd");
tempDate = formatter.parse(lnDateStr);
formatter.applyPattern("yyyy-MM-dd");
lnDateStr = formatter.format(tempDate);
lnVenFcastDate = new oracle.jbo.domain.Date(lnDateStr);
// setting the two attributes with input values
rowln.setAttribute("VendorForecastDate", lnVenFcastDate);
rowln.setAttribute("VendorComments",PohdrComments);
}catch( Exception e)
currErrorStatus = err.putErrorDesc(e.getMessage());
err.setCurrentErrorStatus(currErrorStatus);
%>
<jbo:RollBack appid="LivePoheaders.LivePoheadersAppModule"/>
<%
throw new oracle.jbo.JboException(e);
%>
</jbo:RowsetIterate>

currErrorStatus = "-1";
err.setCurrentErrorStatus(currErrorStatus);
}catch( Exception e)
currErrorStatus = err.putErrorDesc(e.getMessage());
err.setCurrentErrorStatus(currErrorStatus);

throw new oracle.jbo.JboException(e);

From the JDeveloper 3.2.3 online documentation:
JBO-25014: RowInconsistentException
Cause: Comparison of the cached entity failed with the values in
the database for that entity. This could happen when another
user or operation has committed modifications to the same entity-
row in the database. This exception can also be thrown if the
equals() method on one of the domain-type attributes in the
entity fails.
Action: Choose from the following options:
--Verify that another user or operation has not modified the
same row in the database. If this entity has attributes of a
domain type verify that the equals() method on these domains do
not fail when comparing the existing cached value with the newly
fetched value.
--For any attributes/columns that are updated by the database,
modify the entity attribute definition by selecting Refresh
after update on the Attribute Settings page of the Entity Object
Wizard.
--Use view.executeQuery() frequently, especially after any
operations that result in data being changed.
