Hi,
that's an interesting decision. When looking at the Vaadin online-demos,
they subjectively appear to be much slower in response than Ext-GWT or
pure GWT online demos. My first thought would be that with Vaadin, all
event handling is done on the server, while with GWT most of it is done
in the browser (except for raw data retrieval, of course).
For example, with Vaadin *any custom click-listener has to be executed
on the server*, right?
That likely means a lot more requests will be sent during typical
interaction, and so performance depends highly on the network
connection. Even given a good network connection, there always is a
latency of a couple of milliseconds, which will always prevent a Vaadin
UI from reaching the subjective "snappiness" of a GWT UI.
Personally I find this a disappointing outlook, after having worked a
fair bit with GWT in Magnolia 4.3, and with absolutely great results.
Yes I have seen
http://wiki.magnolia-cms.com/display/MAGNOLIA5/Architecture+-+Decision+Table,
and yes there is a lot more factors than performance. But think for a
second how compelling /from a user's perspective/ the performance of a
GWT interface is, when comparing it to competitors' UIs. IMHO, GWT would
give Magnolia an absolutely great competitive edge.
With Google having bought Instantiations' GWTDesigner (as somebody on
this list already noted), IDE support is likely to become just great for
free as well.
Regards,
Jörg

After some controversial discussion the team has finally decided to go
with Vaadin. More details will follow - no later than at the
conference ;-)
Exited and looking forward ;-)
