How can I build a Web App with Component Combination

I learned OpenUI 5 for a while, since it's open source version release. It's really a great web front-end framework!

Now I'm working on a little web app. I design it start from a root module. And I wanna make any other view modules as a stand-alone package. (e.g. Something like Widgets can be make as a Component, and I can instance it anywhere I want). From learning of OpenUI, I think Component should be a good choice for my web app module.

But there is some trouble. When I make two Component with a parent-child relationship.Once the child Compont's router execute navTo method, the hash will be replace but not append. And the parent Component will be changed too.

The question is : how to design the route pattern can make the parent-child Components works both fine? Andreas Kunz
