Add tests for capabilities which have been updated to work
when only a model (and not whole objects) are cached; that
change was introduced to prevent misbehavior of the Remove
action in Edit mode, WTD-473.
Utilize model cache, permitting object models in edit mode to
be reused across multiple distinct instances with unique
contexts (unique contexts are necessary to avoid ambiguity in
the Remove action, WTD-473).
To avoid infinite digest cycles as a consequence of this,
refactor context/composition capability wrappers such that the
former is idempotent (since idempotence is no longer ensured
by the EditableDomainObjectCache) to avoid infinite digest
errors in Edit mode.
Fix a defect in the Save/Cancel buttons in Edit mode
that was causing the first click to be missed; this
was due to Angular's inability to detect when a
native promise (as opposed to one from ) had been
resolved.
Since the Editor capability is introduced indirectly
and is a few degrees of separation removed from
the declared extension layer (where we would be able
to get a reference to ), and all we need to do is
make something look Promise-like, a convenience
function to do this is added.
Part of ongoing transition of common user interface
elements, WTD-574.
