Hi,
Yes, they are getters.
I now solved the problem by marking the metrics as <derived> which means that they
do not get saved. This was needed in any case. But, still the error that we got in Fuel
might still be around.
Cheers,
Doru

Hi,
Interesting observation. Perhaps, the problem could come from the following situation:
We now introduced meta-described properties for MooseEntities that compute the values
lazily.
I forgto to say something. I don't understand why while traversing the graph we could
trigger that lazy computation. Are they getters? can you imagen a why that we execute them
(even without wanting) while traversing the graph?
Furthermore, the values are not stored in instance variables, but in a dictionary in
MooseEntityState.
Indeed, that sounds related to the problem. I really never touch a line in the Fuel
extension for Fuel nor to the Moose model, so I can be asking non-sense. Anyway, we have
this method:
shouldIgnore: attribute withAll: values
"Copied from FMRepositoryVisitor>>ignoreProperty:withAll:"
^ values isEmpty or: [
attribute isDerived or: [
attribute type == FM3MetaDescription boolean and: [
values size == 1 and: [
values first == false ]]]]
or
attributes
^attributes ifNil: [ attributes := (repository metamodel descriptionOf: theClass)
allAttributes reject: [ :anAttribute | anAttribute isDerived ] ].
and things like that... so may question is , maybe there are some new
attributes/properties which should be considered as derived for example?
cheers
I am not sure how exactly you are traversing the object graph and what you are
serializing. I thought that you go exclusively through the meta-description. In this case,
you should not have this issue at all. But, if you get to the object level, things can
change.
Cheers,

Yes, I couldn't invest many time to the fix
it. I will continue during the week.

Hi,
Any news related to this topic?
Both Martin and I could reproduce the problem but we couldn't fix it. We are a little
bit busy because we are finishing the paper... If course Fuel can serialize Float, so the
problem is in another place.
So far we think that there is some instVar than changes while we are serializing the
graph. Like if at the beginning it was 0.0 but then something different. So it looks like
a instVar which is a float and changes while we are serializing it. That's all we can
get for the moment.
