Camunda Modeler version: 2.2.0
Camunda Engine version: 7.0.4-ee

In the modeler when I set the “Called Element” property it adds the following XML to the call activity…

… camunda:calledElement="CallActivity">

During deployment of this BPMN.xml I get the error below…. Removing the “camunda:” prefix from the “calledElement” resolves the problem…

Caused by: org.camunda.bpm.engine.ProcessEngineException: Missing attribute 'calledElement' | CallActivityParent.bpmn | line 8 | column 92
