UML profile and Acceleo issue [message #1759530]

I am currently testing out the DSL capabilities of Papyrus in combination with Acceleo and I am currently encountering a problem.

I created a simple relational database metamodel using UML 2 profiles with Papyrus:
index.php/fa/29039/0/

I then created a gruesome library model using the meta-model defined:
index.php/fa/29038/0/

Then I created a very very simple Acceleo template file, in which I try to print some elements' stereotypes :

[template public generateElement(p : Package)]
[comment @main/]
[file (p.name.concat('_debug.txt'), false, 'UTF-8')]
Creating file for package [p.name/]
Stereotypes: [for (st : Stereotype | p.getAppliedStereotypes()) separator(',')][st.name/][/for]
[/file]
[/template]

When I use the OCL console on my model, "getAppliedStereotypes()" works just fine. But when I run my Acceleo, there is nothing behind "Stereotypes", even though the generator terminates without any error code...

Do you have any idea what is going on ?

How did you reference your database profile from your model? I guess, you did not register this profile, i.e. you reference it as a profile stored in your workspace via a relative path. Acceleo has had problems with URI resolution in the past. Thus the problem might be related to this issue. You can try what happens if you use an existing, registered profile, e.g. the UML2 standard profile. Also look at the error logs.

Keep also in mind, that Acceleo loads a separate copy of your model and profile into its own resource set. Thus, it will work on the last saved state, not on the current model in a Papyrus editor.

I guess that makes sens considering we can only use Acceleo with registered models, though I did not think we had to do the same thing with profiles.
I can use Acceleo with any registered model, so that must be it.

Thanks a lot for your help.

Though I have now an additional question: how can I register a profile? There is no such thing as "register" in the context menu when I right-click on my UML 2 profile (ie the .uml file) like for eCore models.

There is a Papyrus specific extension point that enables you to see your profile in the list of registered profiles. Typically, your profile is part of a plugin and you also specify a pathmap (which implies that you still change the profile location later without invalidating existing models that apply the profile). The snipped below shows such an example.

 <extension point="org.eclipse.emf.ecore.uri_mapping">
	<mapping
		source="pathmap://DATABASE_PROFILE/"
		target="platform:/plugin/<your plugin name>/resources/profile/"/>
</extension>

<extension point="org.eclipse.papyrus.uml.extensionpoints.UMLProfile">
	<profile
		description="My database profile"
		iconpath="platform:/plugin/<your plugin name>/resources/icons/..."
		name="Database profile"
		path="pathmap://DATABASE_PROFILE/db.profile.uml"
		provider="..."/>
</extension>

Hi Ansgar Radermacher,

We are facing a similar problem on our project.
Let me start off by including the Papyrus profile project structure index.php/fa/29726/0/

and the extension points configuration index.php/fa/29727/0/

We then exported the plugin by the means of an Eclipse plugin
index.php/fa/29728/0/

Finally we were able to add this plugin as a dependency for the Acceleo project,however we weren't able to add the meta-model into the generation .mtl file
index.php/fa/29730/0/

Can you please clarify where we need to add this code segment in acceleo project/file??

Hi

If you pick up an old thread, you need to be much clearer. The preceding comment has no code to add. The comment preceding "Thank you very much ! It works like a charm." added extension points to plugin.xml, but I wouldn't call extension points code.

What do you want? What have you tried?

Regards

Ed Willink

Hi,

as already said, the problem is not clear. Does Acceleo work with your profile in the 2nd (debug) instance, but not when deployed? In this case, check whether the build.properties contain the profile (at least the .uml file).
