Re: Help me to understand the source of Grid

The onAction event will trigger a page-reload, as the currentpage parameter
is passed from the Grid to the Pager:
  @Component(parameters =
     { "source=dataSource", "rowsPerPage=rowsPerPage",
"currentPage=currentPage", "zone=zone" })
     private GridPager pager;


It will also be 'reflected back to the grid component' once it changes, as
the Grid component defines the parameter as 'persist':

  @Persist
     private Integer currentPage;

The next page reload will take the newly selected currentpage as starting
point.
Thanks a lot. I wasn't aware that the parameter binding is 
bi-directional. it's really cool!
