I need a tree drag n drop component...but this component does not appear in gwt samples...
I do not understand if Vaadin, under LGPL licence mean that I will need to pay for my 'commercial' application ?
Can I develop my own drag n drop tree component in GWT (is it complex) ?

In GWT 2.4 there will be drag and drop support I think. With this new feature you can add drag and drop support to almost every widget. Right now 2.4 is in bèta. At Google I/O there was a sessions about GWT and drag and drop. You can watch it here: http://www.youtube.com/watch?v=KEkR1ox_K10
