Job Chains view refreshes too frequently to allow a user to perform any operation

Current Situation

• When an order is running, and you view it the Job Chains view, it continually resets/refreshes such that a user cannot correctly select an action from the "Action Menu" for any job or job node.
• This behavior occurs if either a number of orders are running in parallel for job chains that are visible with the Job Chains view and/or if orders move quickly between job nodes.

Desired Situation

• At the point in time when the user hits the "Action Menu" then all refresh operations should be delayed. Incoming events during the period when the "Action Menu" is open are queued. After the "Action Menu" is closed the queued events are processed and a refresh occurs.
• This behavior could cause errors: if a user e.g. tries to "suspend" a running ad hoc order but requires more time to find/hit the "suspend" action menu item than the order needs to complete, then the "suspend" operation might not be successful for the completed ad hoc order. In this situation the user should be presented the respective error message.
