[Acceleo] Cannot access a class's package attribute [message #494425]

Dear all,

Can anyone explain what is wrong with this template?

[module syntaxerr('http://www.eclipse.org/uml2/2.1.0/UML')/]

[template public syntaxerr(c : Class)]
	
	[comment @main /]
	[c.package/]
	
[/template]

I get a syntax error in the MTL editor, and the message:

Quote:

token 'package' is invalid

I paused after typing 'c.' and selected 'package' from the drop-down list. If I use 'namespace' instead of 'package', it works fine.

I am using the Galileo modeling SR1 release (Linux x86_64) with Acceleo 2.6.0 installed from the Acceleo update site.

Thanks for any help,
Peter.

P.S. In case anyone is wondering what use a template like this is, I would really like to use [c.package.name/] , but need to get past this error first.

Hi Peter,

That's a collision between OCL keywords and UML choice of feature names.
To access UML's "package" attribute, you need to use "_package" in OCL.
The same will be true for most collisions such as this one.

Hi Laurent,

I had been looking at the OCL standard, but hadn't spotted the collisions with the keywords...

Merci!
Peter.
