PHP Fatal error

[SaylorZhu]

PHP Fatal error: Class PHPMentors\Workflower\Process\WorkItemContext contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (PHPMentors\Workflower\Process\WorkItemContextInterface::getWorkItemId)

[ateodorescu]

The WorkItemContextInterface class needs to be refactored. The Workflow base classes have been recently changed.
