Get Value of the TextArea [message #1781379]

Hi,

I would like to know how to get value of the Widget/TextArea which comes in a Dialog when a tool is used. Basically, I want to print out that value in console with System.out.println(value) where I call it from a custom Service when "OK" button is pressed.

All I want to do is this;
index.php/fa/32017/0/

Hi
Generally to save any value of any widget we have to give a Eattribute in Ecore and then give that attribute name to the value expression and feature name in set of the widget
Steps
1.Create a Eattribute in Ecore
2.Do generate all and run
3.Go to design go to particular widget open the properties window
4.Give the Eattribute name in the Value Expression field(Example feature:Eattribute name)
5.Right click on the change context under new operation u will find set select that(ignore if Set action is already present)
6.Give the Eattribite's name as the feature name and give var:newValue for value expression of set

To print the value give system.out.println(getEattributes Name())
the get method of the variable will be present impl class

Hi,

The documentation for Text Area is available here https://www.eclipse.org/sirius/doc/specifier/properties/Properties_View_Description.html#text

You have the variable "newValue" available in your model expression.

To do what you want you can add a change context with an aql expression calling a service with newValue as parameter: aql:self.myService(newValue)
