  • Error: ‘google’ is undefined in IE8

    While using the Google Api forOrg chart generation I came across the error “‘google’ is undefined” when i was testing it in IE 8 browser. The same code was working fine in Mozilla FireFox . Google the error was not able to find solution.  After lots of searching fixed it by doing a small one character change in the URL. Can you guys guess what would be that?

    <script type=”text/javascript” src=”http://www.google.com/jsapi”></script>

    with

    <script type=”text/javascript” src=”https://www.google.com/jsapi”></script>

    Its really frustrating. Dont know this is the solution for this or not. But it worked for me!!

  • Salesforce: SF:INVALID_SESSION_ID

    I was constantly getting exception when I tried to use the “/soap/ajax/15.0/connection.js” in the VF Page.
    JavaScript throws following exception:-

    Invalid SessionID

    {faultcode:'sf:INVALID_SESSION_ID', faultstring:'INVALID_SESSION_ID: Invalid Session ID found in SessionHeader: Illegal Session', detail:{UnexpectedErrorFault:{exceptionCode:'INVALID_SESSION_ID', exceptionMessage:'Invalid Session ID found in SessionHeader: Illegal Session', }, }, }

    The exception was resolved when I added following statement before using the “sforce.connection” object in the JavaScript.

    sforce.connection.sessionId = “{!$Api.Session_ID}
