[jboss-jira] [JBoss JIRA] (DROOLS-31) RowAdapter should not throw Exception when Object not found

RowAdapter should not throw Exception when Object not found ----------------------------------------------------------- Key: DROOLS-31 URL: https://issues.jboss.org/browse/DROOLS-31 Project: Drools Issue Type: Enhancement Security Level: Public(Everyone can see) Affects Versions: 5.5.0.Final Reporter: Ryan Nideffer Assignee: Mario Fusco RowAdapter throws an undocumented, unchecked exception if an identifier passed to get() does not exist as a row in the returned query. This pattern is not ideal, and instead should simply return null, thereby allowing clients to easily skip non-existent objects much more cleanly and more lightweight than exception handling. Additionally, the ViewChangedEventListener interface does not provide a way to know which query was invoked for the callback. It is cumbersome to create per-query ViewChangedEventListener objects which allows you to avoid querying identifiers that you know exist in the query result callback.
