Parameters


• parameter DOMAIN = "Ensemble";
• parameter USEKEEPALIVE = 1;
Control whether we use a KeepAlive in subclasses of this page.

Properties


• property keepAliveInterval as %ZEN.Datatype.integer [ InitialExpression = $select(..#USEKEEPALIVE: ($select(%session.AppTimeout < 60: %session.AppTimeout - 2, 1: %session.AppTimeout - 30)) * 1000, 1: 0) ];
The interval in milliseconds at which keepalive events should be triggered. A value of 0 is used when USEKEEPALIVE is 0 - this indicates that no keepalive is in use. The default value is 30 seconds less than the CSP application timeout, but this is reduced to 2 seconds less than the timeout if the timeout is less than 60 seconds.

Methods


• classmethod %AddCSPShareHyperevents() as %Status
Add a modified version of cspIntHttpServerMethod to the page to force hyperevents to specify CSPSHARE in requests to the server.
• classmethod %AddEnsExceptionHandler(pIsModal As %Boolean = 0) as %Status
Add centralised error handling for standard pages and dialogue windows.
• classmethod SimpleKeepAlive(pString As %String = "") as %String [ ZenMethod ]
Simple method for the client to call.
• method addPopupSuffix(popupName) [ Language = javascript ]
Add a suffix to the popup name to avoid name collisions.
• method clientKeepAlive() [ Language = javascript ]
Simple call back to the server.
• method inResizeLoop() [ Language = javascript ]
Helper method to allow pages to detect when they are in a resize loop under IE8.
• method initPopupSuffix() [ Language = javascript ]
• method onServerMethodError(err, errObject) [ Language = javascript ]
Override onServerMethodError to funnel HyperEvent errors through the central Ensemble exception handling code. If session pollution occurs while in Studio mode, alert the user to the problem instead of reloading. The method sets zenPage._staleStudioSession to true to ensure that an alert is displayed only once and subsequent hyperevent failures will not trigger a reload of the page.
• method removePopupSuffix(popupName) [ Language = javascript ]
Strip the suffix from a popup name created by addPopupSuffix().
• method startKeepAlive() [ Language = javascript ]
Start the client keepalive.
• method stopKeepAlive() [ Language = javascript ]
Stop the client keepalive.
