I think that the first things you need to understand are that: 1. SIGNAL ON ERROR and SIGNAL ON FAILURE apply to non-zero host command return codes ONLY. 2. SIGNAL ON SYNTAX can be used to trap invalid REXX statements not caught by the interpreter/compiler scan. This includes things like division by zero, invalid BIF args (e.g. word(x, y) where y < 0), and invalid interpret targets.
Note that these two error sets are mutually exclusive, except if SIGNAL ERROR (e.g.) is executed explicitly. I haven't used ooDialog, so I can't answer your specific question, but I'm fairly sure that it does not use host commands. Therefore you should not even consider SIGNAL ON ERROR or SIGNAL ON FAILURE to trap ooDialog errors. I hope this helps.
