  • I have checked that this bug appears on Chrome
  • I have specified the version: latest
  • I have specified my environment: All
  • my computer: Windows

Steps to reproduce

  • Have a tool/widget with three operations A, B and C with B child of A and C following sibling of A. By default, the self is a model element foo. A changes the context from foo to bar. B sets a value of bar. C sets a value of foo.
  • Create a model based on the initial metamodel and a representation and execute the tool/widget.

Expected behavior

The correct attributes of foo and bar have been modified.

Actual behavior

Only bar has a modified attribute. If the attribute the language designer wants to modify for bar is also present in foo, the attribute of foo is modified instead of the bar attribute.
The changeContext doesn't introduce a new context where the value of self is only modified for its children. This has side effects on the next siblings.
