Thanks Philip!
While testing the workflow example, I recognized that two validation features do not work anymore for the Workflow example:

The label edit validation should prompt Name should be unique while typing. Currently, this only works for the Push node, as here the name and label text value are identical. In general, the name and label text values differ for most task nodes in the example workflow model.
As I could observe, the label edit changes the label's text and the validator checks the name of a task node instead. Could we align the behavior to get the correct label edit validation?

Thanks for the update Philip! The label edit validation works now as expected! 🎉

Unfortunately I didn't elaborate my comment enough.
The validation in the WorkflowModelValidator (if a task name starts with an upper case letter) is also broken, because there is no dedicated compartment in the taskNode anymore (see validateTaskNode_labelStartsUpperCase ).

Could you have another look? Thanks!

Thanks for the great catch! I fixed the workflow validator in 453b347.

Great, thank you Philip for the quick fix! Looks great! 👍

I would have one final minor request, I just realized the file headers should be updated to -2022. Thanks!

Thanks, I updated the headers.
