@elitastic I think by “optional” parameters you are actually referring to unconfigured parameters. Those parameters will be put to query string ultimately. And by changing the value of querystring, you cannot trigger a transition, because there are no changes in the configured part of parameters.

However, I have revisited your earlier [thread](https://discourse.aurelia.io/t/router-lite-navigate-to-optional-param-within-same-route/5115) and it seems that my PR not yet fully supports the Au1 use-case. Let me find a solution for that.

In the mean time, here is an working workaround: [routing within same route v2 (forked) - StackBlitz](https://stackblitz.com/edit/au2-conventions-ksibj3?file=src%2Fmy-app.ts)
