I don't need to assign the external dispatcher, because it is already
available as _strand inside model, is that what you mean? I missed seeing
the wood for the trees there.
I guess I was looking at it from the outside-in via the controller which
seemed to be first to start adding listeners to the model, and not thinking
about the model as having the 'external dispatcher' (_strand) reference
already, so that's a good thing to have my eyes opened about :). Thanks!
In terms of IEventDispatcher-ness, what I was trying to do here was to make
something that worked within what I understood to be the 'current
conventions'. In order to do that I actually wanted the API surface to be
the same, because I assumed that those conventions were 'how we do things
around here' (the existing code is all I have to determine this, and I did
not follow the rules the first time, so I was trying to both 'follow the
rules' and make improvements). I think a lot of existing code which
involves adding listeners to the model should continue to work with the
type of approach I used (making allowance for the change from
'selectedIndexChanged' to 'selectionChanged' etc) .
But changing the events in the model all to something like
_strand.dispatchEvent('selectionChange') definitely could work too, and the
model need not be an IEventDispatcher at all, as I mentioned previously - I
had just considered that approach as 'too radical' when I thought about
what appeared to be the current conventions. It's clearer now to me that
you are not afraid to change those :).
That will require scouring all the code that currently adds listeners to
the model and finding ways to ensure it explicitly listens to the top level
component (the one that is being supported for binding) instead, and making
sure that the current strand which represents that does not change inside
the model if the model gets shared (as it does for example in combobox).
Probably the first strand assigned could be considered the dispatcher, and
kept as a reference I guess. But I won't have more time to spend on this
probably for a couple of weeks now. I think what I did so far is an
improvement for now at least, and a partial transition towards what you
suggest (within Jewel, anyway). Hopefully when Piotr can test what he is
using it for, it will help with the issues he was seeing.
fwiw I haven't seen binding event loops or any issues like that yet either.
