on the off chance that not only igor is patient with this thread....
i noticed that there is an inconsistency (in my view) in how input is handled:
there's Component.getInput()
then FormComponent.inputAsStringArray()
which is used to set
convertedInput - by convert()
and
rawInput - by inputChanged()
which are used all over the place. for example, getValue returns the rawInput
if it was set and getModelValue otherwise (which, btw, uses the converter
directly, rather than calling convert()). this may cause surprises.
for convertedInput, i think it should be considered a caching value. the method
getConvertedInput() should check it, if it is null, it does the conversion and
sets it. it then returns it. calling 'convert' explicitely from other places is
not needed. whoever needs a converted input should call getConvertedInput.
i don't know about rawInput, and why it is used, so i can't comment much, but i
also think it should be used as cached value. it seems odd though, that
getInput is not 'raw' enough.
of course inputChanged should just invalidate the caches.

you mean the sum of correct pieces is not always correct itself?!?
you can create a validator that performs the same aggregation and
checks that i suppose.
also, there's a convert() method in Component, what if i want it to
be employed also?
if you want the whole form workflow to be employed then go about
this differently. instead of overriding updatemodel() override
getInput(), aggregate all the raw inputs from all the children and
use that to feed the aggregator. that way you get the whole workflow.
yep, and also inputAsStringArray
oops, cannot do that. it is final. maybe i can override getRequest...
no, getRequest is also final.
thank you for your patience
