Cons related to Vaadin?

Question

Hi I am evaluating Vaadin framework for one of our project. I went through blogs, sites and found many pros of using this framework, but couldn't find much about concerns related to this framework. I am looking for any cons you found using this framework or any issue you faced during the development of your application using Vaadin, its area of improvement. Any information will be helpful.

Thanks...

Answer 1

• Vaadin is fast,and stable
  
• there is not much documents tutorials and articles about it, "book of vaadin" is your friend
  
• Vaadin has a great eclipse plugin wich saves you a lot of time and work.
  
• Vaadin should use the powerful eclipse rcp tools(equinox,birt...), what eclipse rap already did, this is the step that we wait for.
  
• Vaadin is compatible with all browsers, most frameworks are slow, or doesn't work at all in internet explorer 6(widely used web browser) , this is why i moved to vaadin.
  
• Vaadin has many widgets , if you need you can use also use gwt widgets.
  
• custom widgets is hard to do(compared to eclipse rap), i wish to get a screencast for all steps of custom widgets programming.
