Ordered list [message #1794847]

Hi!

So I developed a representation of a DSL with Sirius. The idea is to relate nodes on a behavior tree-style in ordered sets. When working with Xtext is easy to realize the order of the items (obviously) but I have no way of realizing it with the graphical syntax. I'm wondering if there's a way of getting the index of each list item and display it in its label. I'm attaching a screenshot to help you understand my idea.

Tell me if you need more info from me.

Best,
Sergio

Hi Sergio,

I suggest you to create a Java service that will retrieve the index of the element and to call it from your label expression in the odesign. You will find a sample here : org.eclipse.sirius.sample.ecore.design

Florian

OK, thanks. The link doesn't work, but I guess you mean something like: https://wiki.eclipse.org/Sirius/Tutorials/AdvancedTutorial#Java_Services

I'll try it and come back with the outcome :)
