Initialize value for datetime control based on available
data, and keep up-to-date with changes from UI. Supports
clocks/timers, which use datetime as an entry field,
WTD-1221.
Don't force date-time inputs to act as if they are
required; allow them to be treated as optional, but
enforce that this only occurs when left completely
empty (as opposed to partially complete.)
Supports WTD-1221.
Set validity of selected location from locator control, to
disallow creation when no valid location is selected (which
is possible due to containment rules.) WTD-962.
Implement controller for dialog buttons sufficient to satisfy
spec; these will be used to launch dialogs to collect user input
for Image Properties et al to complete toolbar for Fixed Position
view, WTD-881.
Add a controller for composite controls; this is used
to flag contained controls as required when they have
been partially filled in (to treat entering one of two
such fields as invalid.) WTD-593.
Implement date time controls up to the point that
they validate, and information (albeit not the right
information) propagates back up to the containing
form. WTD-530.
Add remaining platform form controls; amend mct-form
and mct-control directives to better communicate state.
Begin working on problem of communicating validation
back out of the form. WTD-530.
Initial minimal working implementation where a
two-way binding between form and form user is
observable.
Notably, change ng-options to options, since
ng-options is terminal (it breaks mct-control).
WTD-530
Bring in previous work on the forms component; this includes
transitioned versions of specific form elements, and the
mct-form direction which generates these. WTD-530
