Hi,

i am trying to validate_and_insert  a record containing a *unique *constraint 
field in a task( to avoid task failure in case of duplicate). But still 
when this occurs (duplicate) task continues to fail (a typeERROR exception 
is raised). When used in a controller validate_and_insert doesn't behave 
like that so i don't get it ?. How am i suppose to prevent task failure in 
case of duplicate record insert( I need to pursue when this occurs instead 
of having a brutal STOP and a dead task).
