Thanks a lot.
Another question... You are using pageValidate to set up thisPerson
property. I'm still little bit confused about page initialization.
What are pageBeginRender, pageValidate and prepareForRender for? Where
to initialize e.g. thisPerson from passed personId parameter? I've
used pageBeginRender, lazy initialization, but which method is
specially designed for this purpose?
