Thanks again to everyone who contributed to this thread.
Based on the discussion here and reviewing the options in depth with Ken
Ray, I've submitted an enhancement request to the RQCC:
Extend behavior resolution to also happen before preOpenCard
<http://quality.runrev.com/qacenter/show_bug.cgi?id=8558>
Here are my notes submitted there:
Currently the engine attempts to resolve all behavior
references for all objects in a stackFile once whenever
that stack is accessed.
While useful, this can give rise to circumstances in
which this causes unnecessary failure of resolution
attempts.
For example, if you have an instance object in a
substack of a standalone which uses a behavior defined
in an external stackFile library, the engine will attempt
to resolve the behavior for the instance even before you
open that substack, and will fail since the behavior
object hasn't been loaded first.
If the engine was extended to attempt behavior resolution
just prior to preOpenCard, this failed resolution would
have no adverse effect, since a new attempt will be made
when that substack is actually opened.
Not only does this avoid unnecessary resolution errors,
it makes behavior resolution more consistent with other
uses of object references in the engine, such as image
references used in button icons and patterns.
Also:
Some time ago I'd already submitted a request noting that the
resolutionError message isn't yet implemented, and have appended that
earlier report with a suggestion for the arguments to be sent with that
message:
