Select Model Element Variable [message #1706960]

Hi!

When creating a new line in a table I am using the 'Select Model Element Variable' to pick existing elements of a certain type.

However, the candidate expression returning the collection of EObject
is fetching elements from other packages too (...eContainer().oclAsType(Package).getModelDependencies().eAllContents()...). As a result I am getting elements from different packages with the same type and name, which makes it oblivious for me from which package they come just by looking at the resulting list.

Is there a way to show the package from which a candidate element for selection comes?

Cheers

You can configure your 'Select Model Element Variable' to display a tree
by enabling the 'Tree' attribute.

Then the 'Root expression' allows you to choose the elements you want to
see as roots of the tree. And recursively on each root and then each
tree element, the 'Children expression' will be evaluated to compute the
element to display as children.

Note that all the root and children elements must be in the result
collection of 'Candidates expression' to be displayed.

You might find more information in the documentation, see [1] (and [2]).

My question is related to this one.

I have written the "Root Expression" that returns the collection of EObjects (say Containers). Now, In the "Children Expression" I want to iterate on all the containers returned in the Root Expression and return the candidate elements within them. How can I do that?

Regards,
Yash
