----------------------------------

             Summary: NPE using yaml DSL in entity's "provisioning.properties"
                 Key: BROOKLYN-349
                 URL: https://issues.apache.org/jira/browse/BROOKLYN-349
             Project: Brooklyn
          Issue Type: Bug
            Reporter: Aled Sage


Using Brooklyn 0.10.0-SNAPSHOT...

Some usage of the brooklyn DSL within an entity's "provisioning.properties" 
config fails. This is because it fails to find the entity in context.

Therefore a config value like {{$brooklyn:config(\"password\")}} will fail (but 
yaml like {{$brooklyn:external(\"creds\", \"test-identity\")}} should be ok, 
because that does not need to resolve the entity).

As an example, add the following catalog item and then deploy the given app:

{noformat}
brooklyn.catalog:
  id: example-entity
  version: "0.1.2"
  itemType: entity
  item:",
    brooklyn.parameters:
    - name: password
      default: myYamlPassword
    type: org.apache.brooklyn.entity.software.base.EmptySoftwareProcess


location:
  jclouds:softlayer:
    waitForSshable: false
    useJcloudsSshInit: false
services:\n"+
- type: example-entity
  brooklyn.config:
    onbox.base.dir.skipResolution: true
    sshMonitoring.enabled: false
    provisioning.properties:
      password: $brooklyn:config("password")
#      password: $brooklyn:external("creds", "test-password")
{noformat}

This fails with an NPE:

{noformat}

In {{JcloudsLocation.obtain}}, we've created a {{ResolvingConfigBag}}. Then in 
{{getComputeService}} we create a new {{ResolvingConfigBag}} from that. The act 
of copying it calls {{ResolvingConfigBag.getAllConfig}}, which applies the 
transform when the map is iterated over. This causes the values to be resolved.

We don't want that to happen. We want the copy to *not* resolve the values. We 
can rely on the new {{ResolvingConfigBag}} to do the resolution later.
