Hi,
What I want :
- one tool in the palette
- multiple choice when I click on the diagram with the creation tool selected
The multiple choice creates element of the same Class but with different "profile",
they are initialized differently.
How I do that :
- one top node for each "profile" with different "feature seq initializer"
Issues :
- It works great only for the first top node.
For the others, the element is created in the model but not display.
It can be displayed only if we done some actions... (trigger the display of the pop-up menu for instance)
So my questions :
- is that a bug or a normal behaviour?
- how can I do otherwise to do what I want? (cf at the beginning)

seems related with this bug : https://bugs.eclipse.org/bugs/show_bug.cgi?id=193116
doesn't it?

Works fine with constraints.
Thx Alex

doesn't work so fine finally...
The problem is that featureA after being initialized can switch from value1 to value2... Or I have the constraint for
the top node, so it disappears...
In addition, I want to have multiple initializers so, multiple values and so a lot of duplicate code. (if it was only
generated code which was duplicated it wouldn't be so annoying but I customise display with another XXXeditPartProvider)
So is there another way to propose different initialization to the user?
Adding a menu item directly in the pop-up menu of creation?
other...

I tried to add a menu item in the pop-up menu of creation...
Some difficulties : the Palette Factory is hardcoded so we can't use extension points :
"org.eclipse.gmf.runtime.diagram.ui.paletteProviders"
I can modify XXXPaletteFactory to add entries (in createXXXCreationTool adding an IElementType to the List types)
But where can I modify the behaviour of the creation for each entries?
How can I distinguish entries with the same IElementType? In NoteToolEntry.createTool, properties are set; can I use
them for that?
