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

             Summary: Can't use YAML dsl expressions for config of 
HttpRequestSensor inside brooklyn.initializers
                 Key: BROOKLYN-330
                 URL: https://issues.apache.org/jira/browse/BROOKLYN-330
             Project: Brooklyn
          Issue Type: Bug
            Reporter: Aled Sage


With 0.10.0-SNAPSHOT...

It seems that, when using {{HttpRequestSensor}} inside a 
{{brooklyn.initializers}}, it does not resolve the config.

For example, if I use {{$brooklyn:config(...)}} to set URI of the 
HttpRequestSensor, then it fails with the error:

{noformat}
Failed to create instance of class 
org.apache.brooklyn.core.sensor.http.HttpRequestSensor: Cannot coerce type 
org.apache.brooklyn.camp.brooklyn.spi.dsl.methods.DslComponent.DslConfigSupplier
 to java.lang.String (config("server.username")): no adapter known
{noformat}

I have reproduced that in the simple test case below (which I'll add to 
{{HttpRequestSensorYamlTest}}):

{noformat}
    @Test(groups="Broken")
    public void testHttpSensorWithDeferredSuppliers() throws Exception {
        Entity app = createAndStartApplication(
            "services:",
            "- type: " + TestEntity.class.getName(),
            "  brooklyn.config:",
            "    server.username: myusername",
            "    server.password: mypassword",
            "  brooklyn.initializers:",
            "  - type: "+HttpRequestSensor.class.getName(),
            "    brooklyn.config:",
            "      "+HttpRequestSensor.SENSOR_PERIOD.getName()+": 100ms",
            "      "+HttpRequestSensor.SENSOR_NAME.getName()+": " + 
SENSOR_STRING.getName(),
            "      "+HttpRequestSensor.SENSOR_TYPE.getName()+": " + TARGET_TYPE,
            "      "+HttpRequestSensor.JSON_PATH.getName()+": " + "$.myKey",
            "      "+HttpRequestSensor.USERNAME.getName()+": 
$brooklyn:config(\"server.username\")",
            "      "+HttpRequestSensor.PASSWORD.getName()+": 
$brooklyn:config(\"server.password\")",
            "      "+HttpRequestSensor.SENSOR_URI.getName()+":",
            "          $brooklyn:formatString:",
            "            - \"%s/myKey/myValue\"",
            "            - $brooklyn:attributeWhenReady(\"main.uri\")");

        waitForApplicationTasks(app);
        Entity entity = Iterables.getOnlyElement(app.getChildren());
        entity.sensors().set(Attributes.MAIN_URI, URI.create(serverUrl));
        entity.sensors().set(Attributes.SERVICE_UP, true);

        EntityAsserts.assertAttributeEqualsEventually(entity, SENSOR_STRING, 
"myValue");
    }
{noformat}
