Which example should we run?

Flubberwurm13 commented 3 years ago

Soory. Just forgot to add: https://github.com/camunda/camunda-modeler-plugins/tree/master/bpmn-js-plugin-moddle-extension-example

nikku commented 3 years ago

I can run the example without any issue on Camunda Modeler v4.4.0 given the steps to reproduce you provided.

You understand that it is a waste of my time to open an issue like this, without pointing to your changes to lead to this bug?

To fix your issue, revise your extension, start small and see at which point it breaks.
