>             Project: Tapestry 5
>          Issue Type: Bug
>          Components: tapestry-core
>    Affects Versions: 5.4
>            Reporter: Jochen Kemnade
>            Assignee: Howard M. Lewis Ship
>              Labels: error-feedback, patch, test

> I just got the confusing error message:
> No object of type org.apache.tapestry5.services.Heartbeat is available from the Environment.
> Available values:
>  * org.apache.tapestry5.services.Heartbeat
> ..
> That happened because Heartbeat had been pushed and popped during the render cycle. The
problem is, that Heartbeat is still a key in the map of available objects, but the list/stack
of associated objects is empty.
> The patch removes entries removes those keys from the AvailableValues values list.
