Retaining route handler state during routing. #175

Closed kansi closed 8 years ago

kansi commented 8 years ago

I have the following router

<Locations  hash >
<Location path="/" handler={SideBarMainList1} />
<Location path="/group_list" handler={SideBarGroupList} />
</Location>

I visit /group_list and change the state of a dropdown list in this route and then go back to /. Now when i come back again to /group_list i cannot see the pervious state being retained.

It seems that with each route change the corresponding component is re-rendered. How can i just un-mount the component and then remount it keeping its state intact ?

Make your state external to the component... like in Flux's Stores. The component's state will be lost on unmount. That's React, not the router.

Agreed, this is not an RRC issue, this is the way React works and you will run into it with any component that conditionally renders another component.
