Lightning:Navigation with page reference issue

Hi all

I am using <lightning:navigation>component and page reference to navigate the user from one component to another component. Basically I am displaying a list of items in first component and the detail in second component. Now if I click on first item, it navigates to second component and displays the details. It works fine for the first time. When the user clicks the another item the second time, the detail of first item is displayed as the second component's INIT METHOD NOT EXECUTED. 

Did anyone has faced similar issue? Please let me know if you have any solution.

Thanks

Above is the code.

The solution in the link did not help as I am using Lighning:Navigation component to achieve this functionality

Hey Hitendar,

I'm having the same issue - a second navigation to a Lightnign Component doesn't re-initialise it. Did you find a solution to this issue?

With thanks,
Andy

Actually - I think I found a work around.
