Problem using LazyModuleLoadPolicy

RedBall23 Jun 6, 2011 12:46 AM

Hi,

I have problem using the LazyModuleLoadPolicy and ModuleMessageInterceptor.

In the context file I defined:

<module:LazyModuleLoadPolicyTag objectId="lazyLoadPolicy" type="{SendContactEvent}"/>
<module:ModuleMessageInterceptor type="{SendContactEvent}"/>

I am using a view stack with auto creation policy.

I dispatch SendContactEvent from module A and in module B I handle the event.

If I don't use the lazy loading everything works fine.

I'm getting the following exceptions:

Dispatch message '[Event type="none" bubbles=false cancelable=false eventPhase=2]' with 3 receiver(s)
Message Target threw Error

Hi guys,

As mentionned in another thread it would really help if one of you could open a jira ticket with a sample application on our bug tracker:

https://bugs.adobe.com/jira/browse/CGM

I'll do what I can to have a look at it this week.

Thx

Hi Nicolas,

I'm writing again because I still can't upload a sample application because I don't have permission to log in.
Can you help me?

Thanks,

HI Assaf,

We're having a look at the Jira issue, in the meantime please post the sample and description here and I'll create the bug myself.

RedBall23 Jun 23, 2011 6:08 AM (in response to Nicolas Yuen)

Hi Nicolas,

Below is my code without using the LazyModuleLoadPolicy, can you tell me what I need to change/add in order to set the lazy loading?

The main application have two buttons, each one navigates to a different module.

Is there any reason to use the LazyModuleLoadPolicy at all?

Using a view stack with automatic creation policy and basic loading policy will have the same effect..

Thanks!!
