Hi. I am new in Vaadin.
I am just reading and fallowing what is in book of vaadin 7.
I made an example in page 82 (4.3.4. Differentiaing Between Event Sources).
It works fine, but I can not get the concept of setComposition method.
What is the exactly setComposition() do?
I already read docs, but it does not helped for me.
Thanks for your kind answer in advanced
Have a good day!
