Hello ,
I’m trying to add some extensions in the future to my bpmn modeler like “implementation” , when testing the example 1 , in the browser when i select the start event the magic property doesn’t appear and i got the error : “children.js:90 Uncaught (in promise) TypeError: Cannot add property __, object is not extensible” and searched for some issues like this in the forum i found this 2 but i didn’t understand how it will be solved , some other solutions where to do the whole work using preact . I don’t know if there is a solution with react .
And thank you in advance for help .
