What's the correct way to go about persisting a GWT Visualization API DataTable?
Should I find a way to serialize the DataTable object or should I write the table cell by cell to a relational database?
I'm trying to build a RIA using the GWT-MVP pattern described here http://blog.hivedevelopment.co.uk/2009/08/google-web-toolkit-gwt-mvp-example.html.
Edit: What about using JSON? Is there anyway I can get the DataTable as JSON?
Looks like someone else had the same question and answered it himself. gwt-visulation-api-datatable-serialization
Your basic options then are: Store cell by cell or use some ORM on the server side to map your datatable to the DB.
