Question

Problem using LazyModuleLoadPolicy

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 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.
Thanks

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!!
