hi guys i have main.xml and summaryView.mxml. Iam trying to pass value from the main.xml into summaryView.mxml

main.mxml
<mx:VBox>
<mx:Script >
<![CDATA[
 import org.entity.project.ProjectSummaryDTO;	
[Bindable]
public var currentProject:ProjectSummaryDTO;

</mx:Script>
<mx:Form width="1094" height="2200">	
<mx:ViewStack id="workflowViewStack" width="100%" height="100%" borderColor="#000000" cornerRadius="4" >
<projectWork:summaryView label="Project Info"/>      --  The inner mxml,not able to pass id here
<projectWork:detailView label="{currentProject.id}"/>  -- This works fine, i am able to see the id.			 
</mx:ViewStack>			
</mx:Form>	
</mx:VBox>

Open in new window


and this is my summaryView.mxml which is my inner mxml

<mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml" 
 xmlns:projectNav="org.view.projectNav.*" creationComplete="init()"
width="100%" height="100%">
	 
<mx:Script>
<![CDATA[
import org.entity.project.ProjectSummaryDTO;	
import mx.controls.Alert;			 
[Bindable]
public var currentProject:ProjectSummaryDTO;
public function init():void {		
Alert.show(currentProject.id, "passing workflow id"); -- This does not work, i dont see the id here 			
}
]]>
</mx:Script>

Alert.show(currentProject.id, "passing workflow id"); -- This does not work, i dont see the id here                   
-- You cannot see id because you currentProject is NULL

<projectWork:summaryView label="Project Info"/>      --  The inner mxml,not able to pass id here

-- You are not passing "currentProject", how inner class should get your instance?

Here is the solution:

<projectWork:summaryView label="Project Info" currentProject="{currentProject}"/>
