> Key: BROOKLYN-329
> URL: https://issues.apache.org/jira/browse/BROOKLYN-329
> Project: Brooklyn
> Issue Type: Bug
> Reporter: Aled Sage
> Priority: Minor
>
> Using 0.10.0-SNAPSHOT...
> I wrote a YAML entity where CouchDB was configured with an initial username/password, and another app that included CouchDB would inject it.
> In each blueprint, I defined a brooklyn.parameter with a default value for the username/password. I used the same config key name in each.
> However, when I ran my blueprint it hung. The CouchDB was waiting forever for the username/password config value.
> I recreated this behaviour in the simpler test case below (which I'll add to {{ConfigParametersYamlTest}}).
> The workaround is to use a different name for the config key in each blueprint. For example, in the outer blueprint above if youchange the name to {{my.param.key2}} then the test passes.
> Debugging it, one surprising thing I noticed is that {{scopeRoot()}} evaluates to be "entity-with-tests" rather than {{wrapper-entity}}.
> {noformat}
> public void testConfigParameterPassedFromOuterConfigParameter() throws Exception {
> addCatalogItems(
> "brooklyn.catalog:",
> " itemType: entity",
> " items:",
> " - id: entity-with-keys",
> " item:",
> " type: "+TestEntity.class.getName(),
> " brooklyn.parameters:",
> " - name: my.param.key",
> " type: string",
> " default: myDefaultVal",
> " brooklyn.config:",
> " my.other.key: $brooklyn:config(\"my.param.key\")");
> addCatalogItems(
