Whoops. Of course, I meant:
setlistener(f ~ "/serviceable", failure[f], 0, 0);
The meaning of the first optional argument is:
0 ... just attach (default)
1 ... attach and run initially
and that of the second is:
0 ... trigger on change only
1 ... trigger on writing -- independent of value (default)
2 ... trigger on writing to node or children, as well
as addition and removal of children
BTW: We might decide at some point that we only want to dialog-apply
if values changed, but this needs more consideration, and one broken
dialog isn't enough reason to convince me. ;-)
BTW2: dialog-{apply,update} should handle an arbitrary number
of <object-name>, not just one.
