Servoy 4.1.0 rc 2

Classic Servoy
4

RC2 seems to have damaged a solution method I have which works in rc1 (I’ve had to revert to rc1 to continue to work). It is a global startup method which, among other things does:

function startup_method()
{
globals.g_my_username = security.getUserName()
etc.
etc.
}

When I start my solution in rc2, I get no value for globals.g_my_username despite logging in successfully as normal. Is this an issue on my end or something that has changed in Servoy 4.1?

Thanks
