Master-Detail Navigation Behavior Problem

Hello,

I am having problem in navigating from Master to Detail.

Scenaio:

Master1 ---> Master2 ---> Detail

Problem and Requirement

I navigate to Master2 from Master1 properly.

When I click list item of Master2 and navigate to Detail, my master page automatically navigates to Master1.

There is no error or such. Detail page gets loaded perfectly but navigation from Master2 ---> Master1 is not required which is happening automatically.

I am using this.oRouter.navTo() method.

Any idea how to deal with this?

Kind regards,

Rauf
