I had this same issue and fixed by downgrading angular-ui-router and ui-router-ng2 to beta.3

[yuxiaomin]

@paulparton so this issue is very likely a regression in beta.4

[rbarilani]

@paulparton fix works but we would like to use the latest version of angular-ui-router and the latest version of ui-router-ng2... @christopherthielen How do you feel about it? Can we somehow help?

[christopherthielen]

closing old issues... I'm pretty sure this is working now. please let me know if not!
