--------------------------------------------------------------------
Adding another useful case:
{noformat}
$brooklyn:entity(attributeWhenReady("cluster.member.first")).attributeWhenReady("main.uri")
{noformat}
This will allow for chaining attributeWhenReady when the intermediate values
are entities.

> Project: Brooklyn
> Issue Type: Improvement
> Affects Versions: 0.9.0
> Reporter: Aled Sage
>
> When using the yaml DSL to look up values on other entities, it would be
> useful to be able to make this more dynamic by getting the entity id from the
> DSL (e.g. from another attribute).
> For example, a slightly simplified example below - note the DSL for "url", to
> retrieve the URL from an entity whose id is set dynamically on the
> {{TestHttpCall}} entity:
> {noformat}
> services:
> - type: org.apache.brooklyn.entity.nosql.riak.RiakCluster
> id: target-app
> ...
> - type: loop-test-case
> name: "Value replicated on all Riak nodes"
> brooklyn.config:
> target: $brooklyn:component("target-app")
> testSpec:
> $brooklyn:entitySpec:
> type: test-http-status-200
> brooklyn.config:
> url:
> $brooklyn:entity(config("targetId")).attributeWhenReady("main.uri")
> {noformat}
