I agree that this scenario would a nice feature to support because
this is smart for simple language suchs as FSM family languages
however:
1/ I would be interrested to see how to create Sirius animation
layer for language similar to Activity diagram (TTC15 -
https://github.com/gemoc/activitydiagram). IE. that requires
additional metaclasses as support for the representation. For
example, in activity diagram it adds the class "Token";
2/ note that currently not only the trace save/restore of the
multibranch timeline rely on on this RTD definition via the "aspect"
annotation in the ecore file; other feature also depends on it :
- the variable view will not be feed correctly too (without
annotation, it is empty)
- the multidimentional timeline will not have any dimension
- with the java engine, the step back will work but will have
no visible effect on data, only the callstack will change
=> the api/service approach should be more than just a helper for
sirius, it should provide an adaptater that provide a
"traceable"/"storable" model of the RTD and its declaration;
both using a generic/standard format so every implied component
could read/write it.
The ecore part with annotation is doing that role in current version
...
I'm not aware of any concrete code/implementation going that
direction yet (from Fabien and/or Erwan)...

I actually implemented an Helper to
retrieve the RTD for animation in Sirius (see the models
tutorial updated a minute ago, that works in pure K3/dsl file)
I think we should neither add the RTD in the ecore manually or
use melange for this purpose and the API is the good solution
(an Helper may be sufficient)
I'll work on it as soon as I can

Actually, when using Melange, Melange is used to produce

be added
manually as if it was produced by Melange. This must
include the annotation named "aspect" that is used to
drive the variable view and the trace storage.
BTW, this annotation name: "aspect" is a legacy and has
probably a wrong name since this is not the fact that is
comes from an aspect (ie. produced thanks to Melange)
that is important but the fact that it represents
runtime data /dynamic information not matter Melange was
used or not to produce it.
We should have a discussion about a better name for it
and open an issue about it
2/ reminder (if needed), the possibility to set back the
full state works only for the concurrent engine which
doesn't rely on the java stack and thus is really able
to reset its full state. The sequential java engine
relies on the java stack, when going backward we reset
the model state but not the java stack state, so we
cannot really run-again it we simply reset the model
state, when reaching the last really executed step, the
engine continue normally

Hi,
the multibranch timeline is able to store/restore
states of the model to explore different futures.
It was working ok when used with melange or when the
RTD are directly defined in the ecore file since it
was based on EMFcompare.
Now, we are using pure K3 and the DSL file so that the
timeline save/restore mechanism is broken. Is there
already a piece of code that save/restore the RTD
defined in the K3 aspects ?
thanks
