[SOLVED] Adding specific nodes from palette [message #1786908]

Hi,

I'm a rookie with Sirius, so maybe my question is a bit stupid (I also tried to find an answer to it in the already stated questions but I couldn't). I created a palette section and some of the nodes in this palette can be dragged and dropped into the diagram, but others not. I suspect it is related to the Reference name in the instance of the node creation item.

The Node creation items that work are directly connected to the main class of my ecore (Mission) by the feature operator. However, the second group of items that inherit from the Pattern abstract class don't. Anyway, the error that I get when I try to add a new node (let's say, createVisit) is the following:

Message: execute

Hello,

In the CreateInstance of your tool, the reference name field is the reference that will contain the new element. For your "Operator" elements it works as the Mission class has a contaiment reference "operator" typed Operator. But this reference can't contain a Pattern element, however your tool is set on the same "operator" reference. Which contaiment reference in your metamodel should contain Patterns element? This is the reference that should be used in your tool.

Regards,
Steve

Thank you for your answer.

I guess that that reference should be "pattern", but I don't know how to reference it. Should I change the context? If so, how do I do it?

There is no "pattern" reference in your Mission EClass. I found one in DelegateOp though. Either it is missing in your metamodel, or the mappings in your odesign is wrong and VisitNode should be a border node of a DelegateOpNode (or DelegateOpNode should be a container mapping). By the way, you have not set the semanticCandidateExpression of your mappings, it's a good practice (improve performances etc) and it will help you understanding the structure of the element you are representing on your diagram.

I implemented VisitNode as a border node of DelegateOpNode. Then, under the Palette section, I created a new node creation whose reference name is pattern. However, I still cannot add a new Visit node, this time without any kind of errors or alarms from eclipse.

Please, see pictures attached.

In VisiteNode mapping, have you set the semantic candidate expression field to "feature:pattern"? The screenshot is cut just before displaying this field.

Yes, it is. I'm attaching the odesing file to illustrate it.

Sorry for being a bit insistent, but do you know what the problem is?

Hello,

The border node mapping VisitNode has no style, you probably forgot it when you moved the mapping.
By the way, I recommand:
- to fill the semantic candidates expressions of the other mappings, for instance for DelegateOpNode, it should be "feature:operator" (you should probably name it operators in your metamodel as it is multi-valued). If this field is not filled then Sirius will look for candidate anywhere in the current project, so you can have unexpected result, like showing an element from a different model of the project. Furthermore, it is far better in performance.
- to define mapping on abstract metaclasses when possible. It looks like some of your mappings are identical for domain classes with a common super class, like StrictOrderedVisitNode, SequenceVisitNode, PattrolingNode etc). You can define a single mapping on "MouvementPattern" or even "Pattern". If you need different display depending on the kind of "Pattern" subclass it is, you can define conditional style. It will be easier to manage your diagram description, create tools etc this way.

Regards,
Steve
