> "Since we don't cache this, a particular backing bean might be called hundreds or thousands of times during rendering of a datatable, if a value binding has to be evaluated for each row. If the backing bean is a Seam component, injection of dependencies will occur for every call, involving potentially thousands of map lookups."
> There is a discussion thread with a bit more data: http://www.seamframework.org/Community/SeamPerformanceOptimization
> The issue is also recognized at the seamframework.org site itself: http://www.seamframework.org/Documentation/TuningTheSeamWebsite#H-IterationDatatableRepeatInTheUIWithValueBindingsThatRunThroughInterceptors
> Since the issue it known, this JIRA report is created for better traceability.
