MessageProbes

[Russell Standish]

Hi everyone,
        I wanted to do a message probe on a message that returns a
simple type (like an integer or floating point.) Unfortunately, when I
do that, Swarm core dumps with a not particularly helpful error
message. The only examples of message probes I can find (in heatbugs)
actually specify setHideResult. I haven't tried this, but I suspect
that setProbedSelector expects that selector returns an id. However,
what is one supposed to do when you want to return a numerical value
to be displayed (the whole point of a Probe). The documentation on the
MessageProbe class seems obscure on this point. Any ideas?

                        Yours in perplexity.
