Using Boolean as context variable throws fatal exception

[tradel]

I'm using WizarDroid 1.1.1 via Maven repo. I have declared a boolean as a context variable:

    @ContextVariable
    private Boolean isUsingSSL;

When I click Next, the program dies with a fatal exception:

EDIT: same thing happens with an Integer. Seems like only Strings are working for me.

Sorry, I swear I had tried both boolean and Boolean. It works now with the primitive type.
