I noticed that the page gets reinstanciated on every refresh and everything gets reset, don't know if this is default behaviourThe managed bean is apparently request scoped. I think it's time to throw away the "visual editor" you're using or to switch to "source code" mode or so and start with writing code yourself. Do not do drag'n'drop, you would become code-blind and you would constantly fight with trivial and obvious problems at code/specification level.
