Fabio,
Thanks very much for clarifying me about this.
What about exception handling in open-session-in-view scenario ?
Begin transaction in every begin request and commit transaction in every end
request ?
Is it an acceptable approach to handle exception in every button click, for
example ? See below:
>>> Begin Request:
OpenSession( ),
BeginTransaction( )
void Button_Click(...)
{
try
{
// Some code block
}
catch(Exception ex)
{
ExceptionHandler.Handle(ex); <---- Session rollback inside ?
}
}
>>> End Request:
Commit( ) , <-- Ignore if tansaction was rolled back.
Close (Session),
Thanks in advance.
