Scenario:

1. I am creating an instance of a class.
2. I am asking the user to select the model element.
3. I am asking the user under which feature this element should be set.

To do step 3:
I am creating a Dialog box where I am showing some radio buttons. I want to get the value selected by the user and based on the selected value I will set the selected model element under that feature.

Question:
1. I am trying to retrieve the value of the radio button selected by the user under begin operation under OK button. The variable "newValue" is not accessible there.
2. Alternatively, I am setting the model element under the begin operation under radio button. But this does not work.

Any pointers? What I am doing wrong here?

I tried this: https://www.eclipse.org/sirius/doc/specifier/properties/Properties_View_Description.html#radio_group

But, the "newValue" is not accessible under OK button. Compilation error Unrecognized variable: (newValue)

Hi,

The variable "newValue" will not be accessible in the OK button. It is accessible in the editExpression of the Radio widget.
You should store it somewhere if you want to retrieve it later on when the user will click on OK (you can store it thanks to a model element, a Java service, etc).

Hi Stephane,

Thank you for your reply.

How can I create the expression variable and store this variable. There is no option to create expression variable and I do not want to use the Java Service because, the begin under radio is excuted everytime the selection changes and I do not want to call java service again and again.

Alternatively, I was trying to create a Switch under "Radio" and based on the radio button selected by the user trying to set the property under the instance of Class. But, it does not work.
