Hello, smartGwt looks very appealing and very rich in features, but it is very slow. This is due to the fact that it is a JSNI wrapper around the Smart Client framework. This means loosing all the benefits of having a pure GWT implementation (I will not go into details on this).
I think a comparison with GXT (also known as GWT Ext, at this address http://extjs.com/products/gxt/) does not make any sense as GXT is a pure GWT feature implementation and it is lightining fast once compiled. The only appropriate comparison would be with gwt-ext (http:// code.google.com/p/gwt-ext/) which is JSNI wrapper around the ExtJS javascript framework (developed by the same company that developed GXT), much like smartGwt is a JSNI wrapper around the Smart Client framework. This forum is full of people complaining about how slow and cumbersome gwt-ext is, and I think exactly the same problems will be encountered with smartGwt.On the other hand GXT is not affected by any of these issues. True, GXT at the moment is not as rich in features at the moment, but they are getting there. I do not work for the ExtJS company, I only talk from experience. I used the JavaSciprt ExtJS framework for a big project for a full year and I understand exactly when people say the documentation is poor and performance slow. Having embranced GWT to progress and to make my life easier, I would never want to to have the same problems again with Js frameworks, even less with GWT frameworks with embed the same old Js issues, like gwt-ext or smartGWT. GXT is a completely different matter and I think it is a top framework. I have been using it for a few months now and never gave me any major issues. It is a pure GWT implementation, no javaScriptObject or JSNI. Period. Huge credit to Sanjiv for his work on smartGWT, but personally I think this is the wrong approach to any GWT framework. JSNI is very useful if used to integrate the odd js function here and there, not as a foundation to a framework itself.
