Alex Heneveld commented on BROOKLYN-329:
----------------------------------------
a few related things for reference:
4) immediate evaluation in general is wonky
5) the ConfigMap.findKeys method never looked at the keys declared on the
container; I'm tidying that in order to test the above
6) if a yaml subtype reclares a supertype's parameter (from yaml) or config key
(from java) only partially, the results are not merged as one would expect, but
instead all parts of the super's declaration are lost
(working on these together with 1/2)
> $brooklyn:config hangs, rather than getting default brooklyn.parameter value

> 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(

> " type: "+TestEntity.class.getName(),
> " brooklyn.parameters:",
> " - name: my.param.key",
> " type: string",
> " default: myDefaultVal",
> " brooklyn.config:",
