grails - vaadin sends a post request for every action taken -

i'm evaluating vaadin plugin grails , 1 of many concers performance.

i developed trivial application having tree set , every time click on item form filled in, fields manually edited , when force save button alter persisted. although impressed speed managed implement such application have concern regarding performances future real application. in particular can see every action take (clicking on item, collapsing tree, etc.) post sent:

is there way avoid this? tried apply setimmediate(false) every component don't see change. snappy right way go?

ideally want accomplish have finish model running on client site , have communication server either when strictly necessary (eg. retrieve info not available when application loaded) or when "save" button pushed. realistic?

thanks attention.

this negative aspect of vaadin, not have things under control. gave vaadin , went pure gwt. http://www.outsourced.sk/1872/building-scalable-cloud-app-using-gwt-jboss-mongodb-on-openshift-part-2-vaadin/
