1. Create a new custom attribute for BPMN Task (type: date, format: "d.m.y")
2. Create a new BPMN 2.0 Diagram with one task and fill the new custom attribute with a value
3. Save Diagram
4. Open Explorer and change the format of your custom date attribute to "d.m.Y"
5. Reload the Editor and view the previously created task with the date value
