Icefaces ace:dataTable lazy loading

Question

Is there anybody who have a little example of a lazy loading with ace:dataTable?.. I can't understand how to implement the load method of the class LazyDataModel.. and how to fetch data from a Database through this method..

thanks!

Answer 1

ace:dataTable has already a "built in" lazy loading mechanism in ICEFaces (at least for release 3.x and up).

No need to extend an AbstractList for this anymore.

All you need to do is add the lazy="true" to your tag, and make sure the "value" attribute points to a class that extends LazyDataModel... you just need to implement the abstract method there that accepts start page, page size, sorting & filtering arguments.

Also don't forget to use pagination and determine the size of the page ("rows" attribute).
