I am developing a M2T generator in Acceleo. The model is basically a UML model with SysML profile created in Papyrus. It includes Blocks and FlowPorts. I have to access these stereotypes but it seems that I cannot retrieve any SysML object even though they appear in list (code suggestion). Actually I have to access 'Direction' property of FlowPort associated with Port. I have already tried suggestions and answers from various forums (including this) but in vain.

The code is given below. I have created java services as suggested by this but port.hasStereotype('FlowPort') always return false. I have also tried 'SysML::PortAndFlows::FlowPort' instead of 'FlowPort'. I use Acceleo 3.6.2 on Eclipse Mars.

...
[template public generateElement(model : Model)]
[comment @main/]

[file ('created.txt', false, 'UTF-8')]
[for(port: Port | model.eAllContents(Port))]
	[if(port.hasStereotype('FlowPort'))]
		OK
	[else]
		NOT OK
	[/if]
[/for]
[/file]
[/template]


I include following metamodels in the Module at the time of creating the module:

http://www.eclipse.org/uml2/5.0.0/UML
http://www.eclipse.org/papyrus/0.7.0/SysML
http://www.eclipse.org/papyrus/0.7.0/SysML/Blocks
http://www.eclipse.org/papyrus/0.7.0/SysML/Constraints
http://www.eclipse.org/papyrus/0.7.0/SysML/PortAndFlows
http://www.eclipse.org/emf/2002/Ecore

Also I do register required packages including following as suggested by https://www.eclipse.org/forums/index.php?t=msg&th=1060450&goto=1693765& in registerPackages() of Generate.java

        // UML2 profiles
        URI uri = URI.createURI("platform:/plugin/org.eclipse.uml2.uml.resources");
        uriMap.put(URI.createURI(UMLResource.LIBRARIES_PATHMAP), uri.appendSegment("libraries").appendSegment(""));
        uriMap.put(URI.createURI(UMLResource.METAMODELS_PATHMAP), uri.appendSegment("metamodels").appendSegment(""));
        uriMap.put(URI.createURI(UMLResource.PROFILES_PATHMAP), uri.appendSegment("profiles").appendSegment(""));  
        
        // SysML profiles
        uri = URI.createURI("platform:/plugin/org.eclipse.papyrus.sysml");
        uriMap.put(URI.createURI(SysmlResource.LIBRARIES_PATHMAP), uri.appendSegment("librairies").appendSegment(""));
        uriMap.put(URI.createURI("pathmap://SysML_PROFILES/"), uri.appendSegment("SysML.profile.uml").appendSegment("")); 
        uriMap.put(URI.createURI("pathmap://SysML_PROFILES/"), uri.appendSegment("model").appendSegment(""));


Any sort of help is appreciated.

Hi

I am sorry that Ihave not used UML with Acceleo so my advice is limited
however...

Provision of the UML registrations was always a pain and got worse after
the upgrade to UML 2.4 and then 2.5 support. A UMLResourcesUtil.init()
helper method was therefore provided. Any failure to use this method is
likely to encounter significant difficulties.

However Acceleo has unfortunately created unique challenges by trying to
fudge an equivalence between edit-time and run-time URIs and so what I
recommend may not be helpful. You need to check whether your style of
UML URI exposition is compatible with the fudge. When I was using
Acceleo for OCL, I needed to override some of the start up methods to
bypass the fudge.

[The "librairies" typo in:

uriMap.put(URI.createURI(SysmlResource.LIBRARIES_PATHMAP),
uri.appendSegment("librairies").appendSegment(""));

probably does not help. There should be a SysMLResourcesUtil.init() to
avoid such typos. Raise a Bugzilla.]

Regards

Ed Willink
