Vaadin/GWT and processing of some events on the client.

I welcome!

Whether probably - to define the output agents of events involved on the party of the client without the reference to the server? In certain cases it happens reasonable, for example, at validation the data entered by the user.

For example, a special case - validation the data before form sending on the server if i need to check up some fields as, for example, here -

But without sending of the data on the server that such checks occurred on the party of the client.
Probably it, or all anyway we have interaction with the server? In this case the concept accepted in
how much strongly differs?


I don’t fully understand your question but the
CSValidation add-on
might be what you need.


I welcome you, Henri Kerola!

You perfectly have understood me, and this add- on just that is necessary for me.
