How to receive result from Selection Wizard
I try to use Sirius for creation of the diagramme of objects UML. As a prototype I use UMLDesigner. As a practical example diagramm Maven POMs for product. In the elementary kind about such:


Peculiarity consists that at creation of a new element it is necessary to choose base element from among existing (class for instance or attribute of class fo Slot). Thus, by the time of creation slots, the attribute of a class should be already chosen (see an illustration from specification UML).


I have thought what to solve this problem (a choice of a class for a instance and a choice of attribute of this class for slot) it is possible with use Sirius Selection Wizard. But it has not turned out!
Has begun with the simple: Selection Wizard InstanceSpecification:


Fig.4 (limit Files Per Message!)

Method for testing of result of work Selection Wizard:


Display of the wizard:


After a select, the method was not started (a tests line is not printed!). Diagnostics about errors is not presented!
Note, I have cleaned the second argument (result of a choice). The method was started!
I cannot accuse Selection Wizard! I do something incorrectly! What?
In Manual о способе получении результата работы Selection Wizard и обо всем, что находится под операцией Begin, нет упоминания вообще.
Friends! Help!

From a quick look at the wizard configuration (in Fig3.png), I think the issue is in your "Browse Expression": it expects the elements selected by the user to be available in a variable named "classes", but the wizard is configured to use the name "element". In your "Selection Wizard" definition, the first child "Element Select Variable" is set to "element": this is the name of the variable where Sirius will place the element(s) selected by the user. You can either change it to "classes", or simply use "element" in your expression, but the two names must match.

Try using "service:getClassesForInstanceSpec(element)" instead (or rename the "Element Select Variable" above to "classes").

That's impressive! Good luck!
