Hi Sylvain,

In particular, the feature the O.P. asked about — the ability to
address widgets as properties instead of by using lookupWidget() —

sure).
It's available in v1 using form.getModel() which I personally
strongly dislike as it provides a value-only view of the widget
hierarchy and forbids all but accessing the values.
I agree. It seems like we've discussed this before. I remember us
talking also about how the "model" terminology there is bad, because
the term "model" should be reserved for "model" in the MVC sense (in
the context of CForms, that's via the binding framework), instead of a
nickname for the CForms-implementation-specific term "FormModel".
But v2 also has other, more essential features that v1 currently lacks.
Please elaborate on these features.
The one I can think of off the top of my head is the ability to set
handlers as properties. So for instance, a function assigned to the
onValidate property would typically (virtually always) be nested
within the flowscript function that created the form, and as such it
has visibility to other local variables declared directly within that
outer function.
Rhino gives us some nice features to implement interfaces or extend
classes in JavaScript [1] meaning you should normally not need anything
special. However, while writing this I tested this in flowscript and,
strangely enough it doesn't work in flowscript whereas it does from the
command line. I'll investigate this further.
I seem to remember that there's at least one other v2-specific feature
that I rely on... but I can't recall what it is, I've been using v2
only for so long now.
You'll have to use V1 if you want to use the nifty Ajax features :-)
