Unable to modify constraint date even when constraint type is set as "Start not earlier than" or "Finish not later than"
In a formal project open a sprint backlog plan. For an existing or new work item change the constraint type to SNET or FNLT. This action should set the Constraint Date editable. But instead a error is shown in the UI and the Constraint Date field does not get editable.Below is the error.
TypeError: this.getPlanModel().findAttribute(_17) is null
