StreamLink for Browsers - Known Issues

The following are known issues with StreamLink for Browsers at the time of release:

• It is not currently possible to open two or more windows within a single instance of a browser (e.g. by using the CTRL-N shortcut) containing SL4B enabled pages that connect to the same Liberator when a JavaScript RTTP provider is used. This is due to a standard configuration option within the browser (both in Microsoft Internet Explorer and Mozilla Firefox), which restricts the browser to only being able to open two concurrent connections to the same server.
• Large data requests made in a single go can result in an error being generated when requesting the data in Mozilla Firefox with the web page loaded from a different web server to the Liberator. This problem only occurs if the JavaScript RTTP provider is used. A possible work around is to break requests up into smaller parts (e.g. request 300 objects in 10 requests of 30 objects per request, instead of all in one go).
• The JavaScript RTTP provider does not work if the SL4B-enabled page is served up over http, whilst the Liberator connection is over https, or vice versa.
• RTTP page objects are currently unsupported by the JavaScript RTTP provider.
• Throttle messages are unsupported by the JavaScript RTTP provider, attempts to invoke the setThrottleObject(), setThrottleObjects() and setGlobalThrottle() methods will result in exceptions being thrown.
• The multiupdates configuration option causes errors on a SL4B enabled page that has requested directory object(s) from the Liberator if an Applet RTTP provider is used.
• The multiupdates configuration option causes a Java/JavaScript security exception in Mozilla Firefox if an Applet RTTP provider is used and the SL4B-enabled page is loaded from a different web server to the Liberator.
• When using the JavaScript RTTP provider, the object creation and deletion methods return undefined, rather than true or false to indicate whether the action was successful or not.
• If you subscribe to a directory, then at a later point use another subscriber to subscribe to the same directory, the second subscriber will receive two copies of the entries within that directory.
• Spaces within object names is not fully supported currently. These spaces may be treated as pluses (+) in some instances. This will not cause the library to fail, however it may result in a "Not Found" response being returned from Liberator as "FIRST+EXAMPLE" is not equivalent to "FIRST EXAMPLE".
• A script error occurs if the master frame is specifically reloaded whilst a slave frame is still open. This results in the slave frame being detached from the master, and it will cease to receive updates.
• The about:blank debugwindowtype attribute is not always reliable for launching a debug console in IE. Sometimes the console displays the error message "DebugWindow Error: Exception occurred whilst processing window.onload ([object Error])". This is due to a timing issue with the document.domain property being set. Refreshing the browser page typically resolves this.
• From SL4B version 4.3, it is not possible for SL4B to request a token from a version 4.2, or earlier, KeyMaster. Please update your KeyMaster to the latest version accordingly.
