[jira] Resolved: (BEEHIVE-1102) implement partial data set support
in the netui data grid
[ http://issues.apache.org/jira/browse/BEEHIVE-1102?page=all ]
Eddie O'Neil resolved BEEHIVE-1102.
-----------------------------------
Fix Version/s: v.next
Resolution: Fixed
SVN 431515 implements this feature and adds a "partialDataSet" flag to the configurePager tag; currently, this only supports rendering a data set of "page size" each time the data grid renders. This could certainly be enhanced to support rendering a page from a partial data set containing 2+ pages of data -- just haven't gotten there yet.
The tests committed with the change provide examples of how this works.

> The NetUI data grid supports rendering complete data sets, but it would be quite useful if the grid supported rendering partial / incomplete data sets. This would allow webapp controller logic to fetch a smaller amount of data from a database or via an ORM framework like Hibernate or OpenJPA.
> There are some changes needed in the data grid to support this -- specifically, the data grid needs to support:
> - a partialDataSet attribute that forces the grid to start rendering data from the beginning of a data set rather than the middle
> - support from the PagerModel to render the "current" item of data based on the value from a URL rather than from the location in the data set
> - support from the data grid for finding the absolute "current" index in a data set rather than the relative "current" index in a partial data set. This would allow updates to work correctly when a data grid or row is updating an item in a data set.
