@channel : isMounted is deprecated. Instead, make sure to clean up subscriptions and pending requests in componentWillUnmount to prevent memory leaks. I’m getting the following warnings in my front end application. Any suggestions to eliminate this ?

I’m using a mixin with (init , did-mount, will-update, will-unMount)

this is caused by depending on another library that imports a new version of react than the one rum ships with. So it's not your code, rum needs to be updated sometime
