Hi
We have the usual EO -> VO -> af:table set up.
In or VO we have a list of values which sets its own attribute and a secondary attribute (AttribNr) which doesn't need to be persisted.
AttribNr value is used in several other backing bean methods.
The value is set as a secondary return value from a list of values.
In the VO AttribNr is marked as "Calculated AttribNr'
When running our application AttribNr is set correctly but as soon as a filter is applied to the af:table AttribNr becomes null.
We have tried to create a transient EO attribute but the same problem occurs.
The only way to prevent AttribNr from being set to null after a filter is applied to the af:table is to mark the EO attribute as persistant, but then the auto generated EO insert/update query contains AttribNr in the field list but as AttribNr doesn't exist in the database table the query fails. (which is understandable)
How can we create a transient/calculated VO attribute which doesn't become null after a filter.
Thanks in advance
Paul
