Trying to use StateObjectFactory...

Hello everyone,

I am using Tapestry 4.0.2.

I want to use an ASO with some security information in it. The
information should be obtained from HttpRequest on the ASO's creation. I
decided to use a StateObjectFactory to create such an ASO and configured
it like this:

<contribution configuration-id="tapestry.state.ApplicationObjects">
	<state-object name="security" scope="session">
		<invoke-factory
object="com.test.util.SecurityBeanFactory"/>
	</state-object>
</contribution>

Then I am trying to obtain the ASO in the page's code like this:

@InjectState("security")
public abstract SecurityBean getSecurity();

The code for the factory was more sensible, but to find a problem I left
just this:

public class SecureBeanFactory implements StateObjectFactory {

	public Object createStateObject() {
		SecurityBean sb = new SecurityBean(new TestUser(), new
TestApplication());
		return sb;
	}
}

However, I am getting an exception:

org.apache.hivemind.ApplicationRuntimeException 

Unable to construct configuration tapestry.state.ApplicationObjects:
Error: Object provider selector 'com.test.util.SecurityBeanFactory' is
not properly formatted. 

What can be wrong here?

Thanks,

Alexander

Hi Alexander,

You need to define a service that you then reference in the invoke-factory:

<service-point id="SecurityBeanFactory" 
interface="org.apache.tapestry.engine.state.StateObjectFactory">
  <invoke-factory>
    <construct class="com.test.util.SecurityBeanFactory">
      <!-- Any config you need here... -->
    </construct>
  </invoke-factory>
</service-point>

<contribution configuration-id="tapestry.state.ApplicationObjects">
  <state-object name="security" scope="session".
    <invoke-factory object="service:SecurityBeanFactory" />
  </state-object>
</contribution>

Cheers

Richard

Hi Alexander,

The way I have done this is to make the factory a service as well.

<contribution configuration-id="tapestry.state.ApplicationObjects">
	<state-object name="security" scope="session">
		<invoke-factory object="service:MyFactory"/>
	</state-object>
</contribution>

<service-point id="MyFactory"
interface="org.apache.tapestry.engine.state.StateObjectFactory">
	<invoke-factory>
		<construct class="com.test.util.SecurityBeanFactory" />
	</invoke-factory>
</service-point>

HTH

Ben
