WHAT I WANT TO DO
I want to define a helper function isVisible() based on allInstances().
PROBLEM
allInstances() and allInstancesFrom('modelname') do not return the
expected results, they return empty sets instead.
Or to be more specific: When I use the debugger to step to this
particular point in the ATL file, the watch variables are empty.
ADDITIONAL INFO
I tried both allInstances() and allInstancesFrom('modelname').
The models referenced by settingsIn, componentIn and scm are NOT empty
and DO contain instances of Setting, Component and SettingComponentMapping.
With other rules in the ATL file, the contents of the component model
are copied as expected (see rule "component"). So it look like the
settings in the launch config and filenames etc. are correct.
I assume that I made some simple mistake, but can't spot the problem.
Maybe is there some special behaviour of allInstances() that I have to
take into account?
Thanks for any hints,
Goetz

Hi Goetz,
You have to do
SETTINGSMETA!Setting.allInstancesFrom('settingsIn')
instead of
SETTINGSMETA!Setting -> allInstancesFrom('settingsIn')

I am now using -> again.
However, I still have a problem: To use the latest version of ATL
(including potential bug fixes) I switched to the latest version from CVS.
Now executing the ATL transformation (See [1] below) fails with the
error message "could not find operation From on MOF!EClass having
supertypes: [MOF!EClassifier, OclType, OclAny]". However, the ATL
transformation does not contain a reference to From(). Could this be
caused by the implementation of allInstances()?
(see [2] for a full stack trace).
ADDITIONAL INFO
- COMPONENTMETA and SETTINGSMETA are independent ecore meta-models,
where SCMMETA is referencing the other two meta-models.
- Also switching on "Allow intermodel references" did not solve the problem.
Thanks for any hints,
Goetz

You cannot use "->" because it is only for collections:
- "COMPONENTMETA!Component" is not a collection, it is a single
element which represents the COMPONENTMETA!Component type
- allInstances & allInstancesFrom are not operations on collections
You must write:
COMPONENTMETA!Component.allInstances()
COMPONENTMETA!Component.allInstancesFrom('InputModelName')

Are you using the standard VM or the new EMF VM?

D'oh! Yes of course. Fixed that. However, that does not solve the problem.

I assume you are referring to the run dialog setting
ATL Virtual Machine = (Regular VM | EMF specific VM)
I tried both. Does not solve the problem.
In both cases I get something like
An internal error occurred during: "Launching generateComponentModel".
operation not found: COMPONENTMETA!Component.From
Any hints?
Would it help if I attach some files from my project?
Thanks for your help,

Hello,
There was a bug in the debugger: contents of OrderedSet was not shown.
It is now corrected on branch R2_1_0_dev.
This problem does not impact normal execution though.
Note that you can also get the value of the OrderedSet using debug:
SETTINGSMETA!Setting.allInstancesFrom('settingsIn').debug('R esult of
allInstancesFrom')
This will display the value in the console during the execution.
Regards,
Frédéric Jouault

Now the bug has also been corrected on HEAD, so it will be fixed for

I updated org.eclipse.m2m.atl.* from CVS.
The debugger now works as expected.
Thanks for the quick response,
