Kss was designed in a way to support event triggering, including the use
case you mention. To support event propagation is an important need for
complex kss application, and it is obviously needed for writing custom
event plugins and also in other use cases where some client state is
involved.
However by the time we wrote triggerEvent / continueEvent, we had only an
example (conceptual) use case to test it on. For this reason they don't
work as expected and altogether they have limitations.
In the last period, I was working on different use cases where a correct
event propagation was needed. I was also contacted by more developers
about the same problem (the need for triggering), an although I was
trying to give solutions and workarounds, the conclusion was always the
same: event triggering must be supported in a coherent way both on the
level of the kss syntax and on the programmatic (javascript) API.
My plan is, as my time permits, to provide a transitional kss plugin,
that can be used on top of existing kss. This would provide the event
triggering in the way I found most powerful and easy to use, based on the
use cases I'm working with and on the requests arrived to me. This will
enable event triggering to be carried out by using kss actions in the
stylesheet. If developers find this usable and they agree that this is
the correct solution for their various use cases, this can be integrated
to kss core at a later point which would result in a clean definition of
the kss syntax and api for event triggering. But even with the
transitional plugin you'd have access to the same functionality with the
tradeoff of a little longer syntax.
Which means you have to be patient at the moment. In case you happen to
participate the kss sprint in Washington DC, I am more then glad to give
you more information about this.
Best wishes,
