Description Gary Xue CLA 2008-04-23 17:05:26 EDT 
This is a request to allow BIRT Report Designer's report preview to use data set data cached locally, to avoid having to issue data set query every time a report is previewed. This is useful when a data set query  takes a long time to return its result, or when such query consumes valuable external resource. 

FEATURE REQUIREMENTS:
(1) BIRT Engine API changes to allow a run task to create/use local data set cache. Introduce new task/API to clear/invalidate data set cache.
(2) Viewer preference setting to enable caching for preview. Add an action in viewer to clear cache.
