That is the precise moment where the error should appear, as all the list has been created using a different Hibernate session from the one you are now in this request ;-)
2005/8/31, Rick Gruber-Riemer <[EMAIL PROTECTED]>:
Hej Martin
The thing is, that this object does not even exist. At least not if I
understand the meaning of a "request" the right way.
What I do is:
# A DAO extending HibernateDaoSupport finds all records or a record with a
specifc id (ScanJourLinkHbmDAO)
# The Page-objects get records or a record by means of a (shared)
manager-class, which has a pointer to the DAO
# Then in danafileResultPage.jsf I have a table, which shows all records based
on DanafileResultPage.java getting the records from the database via manager
and DAO
# Each row in the table contains links to edit a record in a new page
(danafileScanJourModifyPage.jsf). The Page object for the new page
(DanafileScanJourModifyPage.java) has a property (idLink) which I access via
a MyFaces <t:updateActionListener> tag. Then in setIdLink(String anId) I try
to get the record from the database by means of the manager, which then calls
the DAO ...
=> I have no pointer to the object in either the Page, manager or DAO class.
So I cannot call session.update(object) :-( And I guess that the call to a
new page is a new request.
Am I doing something wrong?
Regards ... Rick
