Create Instance in Tree Description [message #1792305] Sun, 15 July 2018 20:29 Go to next message

Hi everyone.

I'm trying to use Sirius to make a Viewpoint with a Tree Description based on a metamodel I have created.

My metamodel has a main class "A" with Class "R" as children and these with "P" as children. In the .odesing I'm showing the current R and P instances in the viewpoint but can't find a way to create new instances of both classes on the Viewpoint. I have searched everywhere for examples of creating instances with Tree Descriptor but haven't found any. Can anyone help me with this?

I already created a Create tool on both parents and children and CreateInstance operation but it does not seem to do anything.

Thanks so much.

Hi,
If create tools are not working, it is likely because they are not defined correctly.
The tool is using the same model operation as the ones in diagrams: https://wiki.eclipse.org/Sirius/Tutorials/StarterTutorial#Add_a_Node_Creation
Can you show us your tool definition?

Hi, thanks for the answer.

I have defined a Create Tool within a Tree Item (I also tried moving it up to be its sibling) with a Create Instance operation.

index.php/fa/33411/0/

My metamodel is as follows. Rule class has a reference to Pattern class. ReferenceArchitecture is the DomainClass in the TreeDescriptor.

index.php/fa/33410/0/

Create Tool has these properties

index.php/fa/33409/0/

And Create instance has these properties

index.php/fa/33408/0/

Hope this helps and thank you again.

Hi,

The Reference Name must point at the reference where the new instance will be added.
So in your example, this will be the "rules" reference of "ReferenceArchitecture".

But first you must set the context right. Your tool should be at the RuleModel level.
I guess RuleModel has as Domain Class "ReferenceArchitecture".

in this case, in your tool, first add a "change context" operation with var:element as expression. So your context is now the "ReferenceArchitecture" instance.
Then your "create instance" operation that uses "rules" as reference name.

This should work.

Also to define Type I recommend to use this syntax Rules::Rule
