Indexdb supporting

[AnutharshaSelvarasa]

Is it support IndexedDB in smart gwt ?

You can used IndexedDB, or other client-side storage systems, via DataSource.dataProtocol:"clientCustom". There is not currently a way to simply turn on use of this storage system by setting a single property; you need to implement the 4 CRUD operations yourself.

So I have to implement javascript methods (JSNI) to use IndexedDB.

Or find a 3rd party GWT wrapper for it, yes. Or there's also Feature Sponsorship if you don't feel up to writing JSNI.
