Palladio is an approach for performance evaluation and design-time performance prediction for component-based software architectures. An important part of the Palladio's tooling---the Palladio Bench---are its graphical editors. In contrast to rudimentary tree-based editors, they enable a more intuitive creation of models even for less experienced developers. However, the maintenance of the current GMF-based editors has become cumbersome, amongst others, because the requirement arose to support an increasing amount of new language features. Thus, we reimplemented the graphical editors using the Sirius editor framework. In this talk, we will present the Palladio approach, the new Sirius-based editors as well as our experiences with the Sirius framework."

Why Change a Running System?
New features should be supported
Regeneration cumbersome
Manual changes in generated code
No extensibility
GMF barely maintained
Last release in 2014
Almost no issues resolved since then
