Hi, I'm trying to use Acceleo tool to transform model to text. I need to have possibility to support incremental changes(user can modify some generated code freely).
I've made small test and found that all my changes overwritten by generated code each time.

[template public generatePackage(anEPackage : EPackage)]
[comment @main/]
[file('classifiers.txt', false)]
[comment [anEPackage.eClassifiers.name/]
[anEPackage.name /]
[anEPackage.eClassifiers.generateElement()/]
[/file]
[/template]

[template public generateElement( c : EClassifier)]
[if (c.oclIsKindOf(EClass))]
[c.oclAsType(EClass).genElement()/]
--[protected('Test')]
--TODO:should be implemented
--[/protected]
[/if]
[/template]

Alexander,

Protected areas have to be unique within each file. What you are doing here means that you're generating one protected area for each classifier of your model, each with the same id ('Test'). Make sure to generate a distinct (but constant for every generation) identifier for your areas. For example :

Quote:

--[protected(c.name)]
--TODO:should be implemented
--[/protected]

Please also note that there should be nothing "after" the identifier, on the same line. Make sure you do not have extra whitespaces after the closing bracket (']') of the first line.
