revert/undo commit SHA-1: c2922e24fd26d813e73a89d76409b4c79962a703 * remove superfluous return statement; actions should return their own return code as they MAY fail (runWithParams):
actions don't return true/false but throw exceptions instead when they don't agree with what's handed to them.
fix #3589 using the proposed tactic. (Aside: Note that the CJSON::decode() is not so sophisticated that it checks the legality of the Unicode characters in the Unicode strings in the input: some illegal stuff *may* slip through that way.)
