Hello everyone,
i have problems with the creation of a node and the set-function. I have a project with sirius and Xtext(DSL). The diagramm represents instances of objecttypes. I like to create a Node-Creation wich sets the name and the objecttype automatically. But the problem is, that the name can be set, but not the objecttype. If i try to set the objecttype like this:
index.php/fa/28348/0/

i can't create a new node.
When i create a new node without the set type function, it creates a new node. I can select the type from a list like this:
index.php/fa/28347/0/

Do you have any ideas, what the problem might be?

Thanks,
Tobias
P.S. Sorry for my bad english

Hi,

The expression in the first screenshot (for the set Type operation) seems to be a simple String. This does not allow Sirius to retrieve the corresponding EObject in the semantic model. You have to write an expression [1] to browse your semantic model to retrieve the corresponding EObject.

Regards,

Laurent
