Doubts on Handling of events in Presenter

[Qrunk]

Hi Thomas,

As you asked, I went through the link(http://www.google.com/events/io/2010/sessions/gwt-continuous-build-testing.html)
but there it was a bit difficult for me to understand the basic reason as to why 

1. we shouldn't use view.getSaveButton().addClickHandler().... i.e to say why we should not have getter in our Display interface?? . What I understood from the video is that it is not a good practice to maintain views state information within the presentation, but sorry to say I didn't understood how is that gonna help us. ? 

2. In that video its also mentioned that we should use setListeners() rather than addListeners(), that is to avoid more than one listener in the interface. 

3. He says he is diverging from Rays understanding of MVP, with respect to not using HasClickHandlers() , please explain why ?   


One of the reason why I couldnt understand the point could be that in that video there is lot of  Google Wave specific code, It would had been easier for me to understand had he used a more generic and a more simpler code to make us understand his point. 

Please pardon me if I have offended any one.


Thanks
