  • Error when using scaffolded ApplicationRequestFactory with IE

    I get an error when I am using IE7/IE8 (firefox works fine) when I create a new GWT module which uses the ApplicationRequestFactory

    I have done the following
    1. created a Roo project from the shell (much like expenses.roo in roo/samples)
    2. imported the project into STS
    3. created a new gwt module which calls the backend (using the ApplicationRequestFactory). The module inherits from ApplicationCommon. When I call the backend I get the error listed below.

    I have tried coping the code from the scaffold class, but I still get an error in IE7/IE8 (not in firefox)

    Any help?, what I am doing wrong?

    Roo: 1.1.0M3
    Java: 1.6.0_20
    STS: Version: 2.5.0.M3
