Diagram element not removing correctly. [message #1783018]

Hello,

I've defined a viewpoint with Sirius.

I want that if I create an element x without a name (name = null) it'll be removed from the diagram (with a remove operation).

It should work but instead of deleting the element from the diagram a red cross appears in it...

Does anyone know what the problem is ? i can't seem to solve this.

Here is the part of the .odesign :
index.php/fa/32236/0/

Here is the diagram element :
index.php/fa/32235/0/

Regards,

Matthieu

Hi Matthieu,

The red cross on the graphical element means the semantic element behind has been removed. In automatic refresh mode (Preferences > Sirius > Automatic Refresh) the graphical element should be removed.
But more generally, create a new element and remove it in the same tool is not a good practice: you should ask for the name before creating the instance and keep it by using a Let [1] for instance. According to the value, you create the instance.

Regards,

Florian

Thank you for the quick answer Florian,

Automatic refresh was already on.

I'm using Sirius 4.1.8 because I must use Eclipse mars.2 (4.5.2) due to my work environment.

Is Let available in 4.1.8 ? I don't think so...
I've thought about something like this but I couldn't find a way to store my name variable.

I'll keep digging.

Matthieu
