[ATL] How to execute many rules in the same atl file [message #538459]

I intend to execute many rules which applied to one input model and one output model. Each rule will transform each different element ( The destination model has many elements needed to be transformed ) . I intend to use helper but every helper must return a value while a rule doesn't return anything. Could you recommend me a solution please.

I do not understand where is the problem.
Each ATL rule applies on the elements matching this rule "from" section.
You can have as many rules as you like (unitl their "from" sections do
overlap).

Actually I'm dealing with the problem of hierachial elements in the target model. To be more specific, I'll illustrate by an example to see if you can help me solve this.
I have 2 metamodel :

And

http://i854.photobucket.com/albums/ab109/capint/BMetaModel.jpg

I want to transform all information from model A.xmi which conforms to A.ecore :

http://i854.photobucket.com/albums/ab109/capint/AModel.jpg

to model B.xmi which conforms to B.ecore.

I tried by this atl file :

http://i854.photobucket.com/albums/ab109/capint/A2BRule.jpg

And the result is :

http://i854.photobucket.com/albums/ab109/capint/BModel.jpg

which is not what I want.

Could you recommend me a solution ? It will be appreciated.

This is a meta-model related problem, not an ATL one, modify your EReferences in B.ecore so set containment to true.
