editExpression for Custom Widget [message #1792306]

Hi all,
I am trying to make ColorPicker example work with my models.
I have managed to set valueExpression so that ColorPicker displays the color from the model features.

However I am unable to set editExpression value. Could you please help with value of the editExpression for ColorPicker widget. References to documentation is also welcome.

Regards.

Hi,

I will answer shortly but please can you keep your answers in this thread and not create a new thread each time when it is on the same subject?

Hi,
Sorry about the similar post.
I checked the links but still not sure what is the correct aql expression to set model properties. If I use a text widget and supple name as feature name property then the value entered to the text box is reflected on the model. In order to achieve the same effect what is the aql edit expression I should use in m custom widget?

Hi,

Sorry for the delay.

Normally, you have two ways.
But because of a bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=537135 you only have one.

In your CustomExpression, you need to use a JAVA service that will do the model modification: aql:self.myService().
See documentation https://www.eclipse.org/sirius/doc/specifier/general/Writing_Queries.html#service_methods
