Basic Dialog Example? Where? Set the name of a created object. [message #1829261]

I'm trying to find a very basic example of using a dialog. I have a node creation tool, and I'd like to pop a dialog up to allow the user to edit the name of the node before creating it.

I found an 11 second video on youtube for Sirius 5.0 that appears to do exactly this with the Family tutorial. I got very excited. Alas, there was no documentation and it just has a link to https://www.eclipse.org/sirius/ and I can't find any docs on dialogs other than two very brief paragraphs that mention "let" for setting a variable.

I can't find an example of a dialog in the Family tutorial that matches the video. The current family tutorial "cheats" and calculates the name for you without an intervention dialog.

I just need a basic example of figuring out how to get the value of a text field and use that variable/value in a set command on my model.

Seems easy, but I can't seem to get it right.

An easy example -> What's the "weird" thing I have to type in the set command to access a text field in my dialog?

Hello

You have many ways to achieve what you want:
* under your creation tool, add a changeContext operation that will call your own java service. This service will pop up a dialog and return the value entered by the user.
* you can also use the "Open dialog" [1] operation that will help you build the dialog without java code

Then add a "Set" operation [2] to change the name

Thank you for trying to help Laurent.

It's the "Set" operation to change the name that I'm having issues figuring out. I'm sure it seems very simple. And after I see it once for the first time, I'm sure we'll all have a laugh that it was mysterious at all.

On creation of a Man Node using the tutorial example, I want to set the name feature of a Man when I hit OK on the dialog. When the user hits OK, I believe that's when I need to execute the create instance operation. When I create that instance, I want to use data from text fields from the dialog I am within.

The dialog has a textfield with the label name.

How do I get the value of the text field in order to set name = value of (name text field)?

When I set name, I want the Value Expression of the set operation to be = "the value of the NameTextField" - but I can't figure out how to express that? What do I type in the Value Expression field to obtain the value of the NameFieldField Text object of the dialog I have created?

I put var: and try to auto-complete and it doesn't suggest anything to do with the dialog I'm within.

I don't think the Text field itself is the entity responsible for setting the name. I think the OK operation should do the setting. Have I got that wrong/

Hello Brandon,

You must use a Create Instance and add a dialog in the Create Instance operation and not the inverse.
I put screenshots to explain you how to do what do you want to do.
To answer your question you must use the variable newValue corresponding to text set by the user in the dialog.
Don't hésitate if you have any questions.

Regards,
