How to access the LightstreamerEngine object from a Push-page

[Mone]

Sometimes the "link" between the LightstreamerEngine and a Push-page is lost (eg. if the Push-page is a pop-up and the opener page - that contains the LightstreamerEngine - gets closed)
Lightstreamer web client detects such cases and notifies the PushPage object.
You should just remember to delete the stored reference when you get an onEngineLost call:

p.onEngineLost = function() { e = null; }
