So, in looking more closely at the logs, I see that the calls that are
being being correctly processed are handled as "AS JS" (where no template
is needed), but the calls triggering the "MissingTemplate" error are being
processed "AS HTML". And yet, in each case, the call originates from the
same button on the same page! *Sometimes* they are being handled as JS and
*sometimes* as HTML.

So now I have to find out what the variable is. A browser issue?

When I find out, I will definitely report back.

This is the call that works:
