[jboss-dev-forums] [Design the new POJO MicroContainer] - setting managed property of type List

[alex.loubyansky@jboss.com]

I couldn't find a test for it? The only test I found for ManagedProperty.setValue() is org.jboss.test.managed.mock.MockTest but it sets only Strings.

I have a property of type java.util.List and when I set it I get

java.lang.reflect.UndeclaredThrowableException

The code looks like
ManagedObjectFactory mof = ManagedObjectFactoryBuilder.create();
  | ManagedConnectionFactoryDeploymentMetaData mcf = new XADataSourceDeploymentMetaData();
  | ManagedObject cfMO = mof.initManagedObject(mcf, "DataSource", "XA");
  | ManagedProperty dsProp = cfMO.getProperty("xa-datasource-properties");
  | dsProp.setValue(arrayList);
  | 
  | 
  | @ManagementObject(componentType=@ManagementComponent(type="DataSource",subtype="XA"))
  | public class XADataSourceDeploymentMetaData extends DataSourceDeploymentMetaData
  | {
  | ....
  |    @ManagementProperty(name="xa-datasource-properties", description="The DataSource properties", managed=true)
  |    public List<XAConnectionPropertyMetaData> getXADataSourceProperties()
  |    {
  |       return this.xaDataSourceProperties;
  |    }

You can see the real testcase in the stacktrace.
