    Unable to load module entry point class

    SmartGWT 2.2
    browsers = IE7, Chrome 6.0

    I am reproducing on my PC the excellent demo at http://uptick.com.au/content/getting-started-smartgwt
    which I imagine is known to many other users

    All was going well up to when I inserted the menu layout (http://uptick.com.au/content/build-user-interface)

    The instruction
    Code:
    // add the Application Menu to the nested layout container 
vLayout.addMember(new ApplicationMenu());
    in the entry point method causes
    Code:
    mainLayout.draw() ;
    the last instruction in the entry point method to generate an error (see below).

    If I comment out
    Code:
    // add the Application Menu to the nested layout container 
vLayout.addMember(new ApplicationMenu());
    no error is generated (but of course the menu is not shown).

    JavaScript error in IE7

    from the error logs, it looks like the menu length is not set
