Vaadin - Lazy Query Container

Question

I'm doing my project in Vaadin 7. I need to implement a Lazy Query Container for a Treetable. I will get data for the Treetable from a web service.

Could someone please show how to use a Lazy Query Container with a web service as my data source?

Please let me know the steps required to implement this or show sample code to get me started.

Answer 1

There is good documentation for LQC here: https://vaadin.com/wiki/-/wiki/Main/Lazy%20Query%20Container

The examples in documentation are implementing MovieQuery using javax.persistence API, but it might be easier to use the simple MockQuery example as basis and replace the actual data fetching with webservice calls.
