Subject Re: [FlexJS] TextInput/Form validation
Date Tue, 20 Sep 2016 15:08:43 GMT
Yes, beads would be a good thing, but IMO, it is only necessary for the
COMPILE::SWF code, since it is the SWF code that doesn't have built-in
functionality to rely on.  Because we have a regular
org.apache.flex.html.TextInput that can serve as the baseline for folks
who don't need these form fields, it is reasonable to think of
org.apache.flex.html5.TextInput as an aggregation on top of
org.apache.flex.html.TextInput so it can get away with baking a few more
things in.

If you look through existing components like Container, you'll see more
beads and support components on the COMPILE::SWF version implementing
non-built-in things in Flash like scrollbars and clipping.

On the other hand, something like the PromptBead is a bead on both JS and
SWF because it can be re-used in more than one component.

So, there isn't one right solution, you have to factor in re-usability of
code vs the overhead of encapsulating it.

Thanks,
