Stale data error while trying to update row.

Question

Hi,
I have a search page, from where i would like to select a particular record and update some of its attributes. But when i try to commit the transaction, i get the error below:
Unable to perform transaction on the record. \nCause: The record contains stale data. The record has been modified by another user. \nAction: Cancel the transaction and re-query the record to get the new data.
My Results table, based on VO1(based on EO), has an image item which submits the page and opens another page with the details of the current record, and provides the user with an option to update one of the attributes. The second page, where the user updates the attributes is based on another VO (say VO2, which again is based on the same EO as VO1).
Behind the Apply button, i call a method in the AM which simply commits the transaction and then re-directs to the original search page and displays the confirmation message.
Pseudo Code:
In the controller for VO1 (search page).
if <update> then
params = config_id ;
am.invokeMethod("initSketchDetails,params) ;
In AM
public void initSketchDetails(String config_id)
vo = getVO2 ;
vo.initQuery ;
In VO2Impl
public void initQuery(String config_id) {
<convert string to jbo.domain.number>
setWhereClause("config_id = :1);
setWhereClauseParams(null) ;
SetWhereClauseParam(0,config_id);
executeQuery();
In the PFR of Controller for the Update Page
if ("apply" != null)
am = pageCOntext.getAM ;
am.invokeMethod("apply") ;
pageCOntext.forwardImmediately to results page ..
AMImpl
public void apply() {
getTransaction.commit();
Where am i going wrong?
Thanks

Answer 1

Hi,
I noticed that this error is occuring only under certain conditions.
In my application a particular record can have 4 statuses (Draft, Submitted, Cancelled and Technical Query). But when a record is being updated, it can only be updated to Draft, Technical Query or Cancelled.
The error occurs ONLY when i am trying to update a record which is in Submitted Status to any other status. If i update a record from Draft -> Technical Query/Cancelled, there are no issues!!!
I cant figure out where the problem lies.
The poplist picks up values from a lookup.
Any idea how to debug this situation?
Thanks
