V-everything - important note about naming stuff in Vaadin
There seems to be a lot of misconceptions about naming conventions in Vaadin applications and add-ons, so I thought I’d better attempt to clear things up right away.
I’ll make sure the following is stated clearly in the upcoming Vaadin 7 tutorials and such, but it applies to v6 too, and is IMHO an important enough point to bring it up right away.
There is a convention that some things (css classnames, client side widgets) in Vaadin are prefixed with the letter “v”. This convention is apparently often copied into add-ons and projects using Vaadin, but:
Please do not prefix your things with “v”, it is a scoping prefix intended for the Vaadin core.
