I want to provide user a jpa entity grid component, which will provide
its own griddatasource and hide it to end user; user instead will
provide an ejbql for the entity grid and the component will execute
the ejbql, generate griddatasource, show results in grid. It's a good
example of simplifying/enhancing an existing component.
My approach would be a GridDataSource implementation that took an EJB-QL
query in its constructor. The advantage is the fact that you can use the
Grid component unchanged. ;)
