Sigma object registration is not removed after the HTML page is shut down.

Issue

Sigma object registration is not removed after the HTML page is shut down.

Environment

Sigma Server (all)

HTML

Cause

The Sigma HTML applet can not send a de-register indication when the HTML page is closed down.

Resolution

When the HTML page is closed down the registered objects are de-registered after about 5 minutes.  

The process for the HTML applet is different to a normal graphic update as it relies on the applet to poll the Sigma server.  The poll interval (ms) is determined by the applet parameter  

<PARAM NAME="refresh" VALUE="5000"> 

Once this stops then the Sigma server will time out and de-register the objects in the controller.
