The setter is the default behavior. It can be possible to use reflection,
but you do not always have an instance variable for a property. Every
MooseEntity has an EntityState that offers a dictionary. This dictionary
can be extended by meta-model extensions, and you can end up with
properties that are actually stored in this dictionary.
For the future we should rework this part and use the slots available in
Pharo 3 instead of the dictionary. For that we need to have the slots be
extensible by external packages, which is not yet happening. This will
simplify the Moose code.
Cheers,
Doru

Hi,
You get the error because you do not have a setter to set the value of the
isFlag property when importing the model.
Why do you need a setter? We can you reflection.

How is this an indication of a problem?

"Every thing has its own flow"
I tried to reproduce it through various ways but
couldn't, may be it was
my image. I'll try to be more vigilant next time. In the meantime, I tried
to reproduce the anomaly with this script, may be we can create a test
(with a dummy class?)?
|model propertyName|
propertyName := 'isFlag'.
FAMIXMethod addInstVarNamed: propertyName.
FAMIXMethod compile: propertyName,
'<MSEProperty: #', propertyName,' type: #Boolean>
<MSEComment: ''A test flag''>
^', propertyName.
MooseModel resetMeta.
model := MooseModel new.
MoosePharoImporterTask new
importerClass: SmalltalkImporter;
doNotRunCandidateOperator;
importingContext: (MooseImportingContext new importClass; importMethod;
importPackage; yourself);
model: model;
addFromPackageNamed: #'Moose-TestResources-LAN';
run;
yourself.
model allMethods do: [ :each | each instVarNamed: propertyName put: true
].
model exportToMSEStream:(StandardFileStream forceNewFileNamed:
'aTestFile.mse').
MooseModel new importFromMSEStream:(StandardFileStream readOnlyFileNamed:
'aTestFile.mse') "should give an error because the propertyName: selector
is absent"

I believe there is some sort of cache that is
maintained somewhere
because it works for me in the new image but if a property is added after
exporting a model to a MSE file, it doesn't work.
Tx André for looking into it.

It worked for me Usman, no problem.
As a test do:
isFlag
<MSEProperty: #isFlag type: #Boolean>
<MSEComment: 'my flag'>
^ true
Then, MooseModel resetMeta.
It will export ok:
=======
(FAMIX.Method (id: 147)
(name 'clearReplacements')
(cyclomaticComplexity 1)
(isFlag true)
(modifiers 'public')
(numberOfComments true)
(numberOfConditionals 0)
=======
Most probably your #isFlag property is nil, then it is not exported in
the MSE file
