Cairngorm 3 Module and Parsley Context initialization problem.

Question

Hi,
   I am using parsley 2.2, cairngorm 3 module library. When the module is loaded the parsley context is not getting initialized at that time and returing null for the objects managed by the parsley container.
<fx:Script>
<![CDATA[
import mx.events.FlexEvent;
import org.spicefactory.parsley.flex.modules.FlexModuleSupport;
import org.spicefactory.parsley.flex.tag.builder.ContextBuilderTag;
[Bindable][Inject]public var faultMgtContainerPM:NMSFaultMgtContainerPM;
public function get contextBuilder() : ContextBuilderTag
return contextBuilderTag;
]]>
</fx:Script>
<fx:Declarations>
<spicefactory:ContextBuilder id="contextBuilderTag" config="{ NMSFaultMgtModuleContext }" />
<spicefactory:Configure />
<s:Consumer id="notification" destination="sessionlog-notification-bus"
fault="faultMgtContainerPM.notification_faultHandler(event)"
message="faultMgtContainerPM.notification_messageHandler(event)"/>
</fx:Declarations>
In the above code the Inject of NMSFaultMgtContainerPM class doesn't work and returing null when accessed in the creationComplete event of the app.
By the way the context file contains the NMSFaultMgtContainerPM class entry.
Please let me know if I am missing any thing.

Hi,
Please have a look at the [Init] metadata from the Parsley configuration : http://www.spicefactory.org/parsley/docs/2.1/manual/lifecycle.php#methods
If you want the Parsley Container to invoke methods on your object when it is created or when it is destroyed,
you can add the [Init] or [Destroy] metadata tags to the corresponding methods:
[Init]
public function init () : void
[Destroy]
public function dispose () : void
The methods marked with [Init] get invoked after the object has been instantiated and
all injections have been processed.
The methods marked with [Destroy] get invoked after the Context instance they belong to has been
destroyed with Context.destroy() or when the object was removed from the Context.
See 6.3 Object Lifecycle Methods for details.
For Flex Components declared in regular MXML files and wired to the Context as described in 7 Dynamic View Wiring
the lifecycle is different: For those objects the methods get invoked whenever the object is added to or removed from the
stage respectively. Of course the [Destroy] method additionally gets invoked if the Context the object
was wired to was destroyed.
Let me know if this works for you
