I can´t create Relationship edge [message #1785825] Fri, 20 April 2018 06:20 Go to next message
Eclipse UserFriend
Hi,

First, I'm sorry for my bad English. I need to create relationship edges between elements but I can't do this. When I click over the element origin, the console shows this:

This message appears ever when i click over the element origin for create the relationship and
when I want to link to the target element.

Some solution?

Thanks :)

Hi,

The screenshot shows the mapping definition. The problem is probably in the tool definition. Could you provide us more details about this tool and the Sirius version?
Your target finder expression should be "[target/]". We recommend to use AQL expression instead of Acceleo3 expression (see https://www.eclipse.org/sirius/doc/specifier/general/Writing_Queries.html#aql)

Regards,

Florian

Hi Florian,

Thanks for answer. I provide the metamodel(metamodel.png) and the definition edge(EdgeDefinition.png) and definition tool for the creation edge between figures in this post(edgedefinitiontool1.png and edgedefinitiontool2.png). My problem, is that i can't link the figure1 to figure2. Howewer, the tool allows the link (problem.png).

I dont understand the problem.

Thank you so much,

Cristian.

Hi Cristian,

In your metamodel, the relation is based on an element of type "Connection" (a Message or an Association). I guess "Secuence" inherit from Connection ?
From what I see on your screenshots, your edge creation tool does not create any instance of type "Connection". As your edge is an "Element based edge", it is the responsibility of the edge creation tool to create a new Instance of this element. And next you set the "origin" and "target" values of the new "Connection" intance.

Regards,

Florian

Hi Florian,

Thanks for your fast answer. I changed my edge creation tool and i added the create instance operation(createConnectionInstance.png). However, I have a problem when i write "object" in the Reference name box :
"Invalid feature 'object' for the following types: proyectoBPMN::Connection" (description error.png)
In my metamodel, Secuence inherit from Connection and Connection inherit from ObJect. Then Lane is composed of Object (metamodel.png).

Thank you so much,

Regards,

Cristian

The problem is the context. You change the context with "var:source". The reference "object" Is on the type "Lane". You have to retrieve to right context. If the context is the parent of the source figure, you will have aql:source.eContainer().

Hi Florian,

Thanks for the answer. Obeo doesnt show me more problems in the "Problems" tab when i put "source.eContainer()" in the Browse Expression, However, I cant create the element "Connection" for link two elements "Figure".For example, I clicked the Secuence tool and I choose the first elemen Figure for represent the origin element but when i clicked in the second element Figure (target) for link with the origin, the IDE doesnt create the element Connection,
He shows me for console:

Im very desperate with this problem. I want only a Secuence,Message or Association element for link two Figures (You can see the Metamodel.png).

Thanks for all,

Cristian.

Hi Cristian,

After an exchange with Florian, we think that the change context must be, Browse Expression: var:source and not source.eContainer().
