Answer 1

The javadocs for UIComponent.setId():
# Must not be a zero-length String.
# First character must be a letter or an underscore ('_').
# Subsequent characters must be a letter, a digit, an underscore ('_'), or a dash ('-').
and you've specified: id="addLegalProfessional and legal organizations"
