Note that 'late resolve' returns 'null' value in normal execution time and
the assignment using it as its left side value is not executed this time
but
only at deferred time.
Also, only assignments are tracked back during deferred execution so you
may use the result of 'late resolve' calls only in assignments to a
property.
If you need to access some properties on it you have to use normal
'resolve'
and gain control over the correct ordering by multiple passes.
Difficult to say what happens in your particular case.
In case you would not find a way to solve that, do not hesitate to come up
with you QVT code, so we can figure out.

Hi, Radek,
I begun the transformation using different passes, one for the main tree
(containment tree) and one for each type of reference, in a very
deterministic approach. But then, I don't remember well why -maybe by
laziness- , I decided to use late resolve with the last type of
reference. As I did not remember this detail, it took me almost two
hours to realize the problem, because looking at the generated target
model, all references were there ;-)
Besides, just to check, I removed the 'late' from the resolves, but it
broke the transformation from the beginning, so I can't see other way
out, other than using the multiple-pass approach to the end. Or am I
missing something?

The 'late resolve' is always to be executed in the end of the
transformation,
just after the body of main() has finished its job.
If you do not want to wait until that time, you can use the available
variants of
normal 'resolve'. In this case, you always get the objects instantly
available
in traces.
As you have mentioned, this requires a bit of specific knowledge of the
transformation writer, in order to know whether neccessary traces have
already been created
based on the execution flow.
Though, I'm not sure, I completely got your problem.
Regard,

Hi,
At some specific parts of my transformation I decided to use late
resolve
:-(. But now I realize that I need some objects halfway through my
transformation - and not at the end, when 'late resolve' resolves the
references.
So, I'd like to know if there is a way of forcing pending references
(to be
used, at my own risk, at some point when I know that all objects from
the
first part of the transformation should already be created).
Thank you in advance,
