Crux - binding model between views

[Maria Jose Esteve]

Hi, let's see if someone can help me or give me some clue to follow.
In the application in which I am working there are many maintenance, mvc, whose 
management is identical. We have created a component SectionContent, 
ModuleSectionContent.as, with the idea of ​​encapsulating in it all the 
processes and / or common components (navigation between the records, detail 
view-list view, toolbars according to the edition status, ...). In this 
template, for example, we add a header (mxml component) as a "Toolbar" that, as 
you can imagine, will need a bindable reference to the "model" that is assigned 
to the component and, at this point, is WHERE I NEED HELP: I can't make the 
automatic binding of the model work, from the main view to the header. 
(Everything works perfectly if I create a set in the template and hence a call 
to the bindable set of the header subcomponent)

We use crux and all the models implement the same interface, IModelArqManager; 
currently this is the implementation:

Component “ModuleSectionContent.as” (Template)

[Bindable]
   public class ModuleSectionContent extends SectionContent
   {
…
       public var header:HeaderModule = new HeaderModule();
…
public function set isOnAddingMode(value:Boolean):void { header.isOnAddingMode 
= value; }
…

Componente “HeaderModule.mxml” (var header)

<?xml version="1.0" encoding="utf-8"?>
<j:Grid
    xmlns:fx=http://ns.adobe.com/mxml/2009
…
private var _isOnAddingMode:Boolean;
      [Bindable]
      public function get isOnAddingMode():Boolean{   return _isOnAddingMode;}
      public function set isOnAddingMode(value:Boolean):void{ _isOnAddingMode = 
value;}
…
<j:IconButton localId="tbProc" unboxed="true" emphasis="emphasized">
              <j:icon>
                     <js:FontAwesomeIcon text="{(isOnAddingMode) ? 
FontAwesome5IconType.PLUS_CIRCLE : 'edit'}"
                   relativeSize="{FontAwesomeIcon.SIZE_LG}" 
faStyle="{FontAwesomeIcon.DUOTONE}" />
            </j:icon>
      </j:IconButton >
…


Implementation, example, CustomerView.mxml:

<?xml version="1.0" encoding="utf-8"?>
<views:ModuleSectionContent
    xmlns:fx="http://ns.adobe.com/mxml/2009";
    xmlns:j="library://ns.apache.org/royale/jewel"
…
    isOnAddingMode="{customerModel.currentState == UtilConstants.STATE_ADDING}"
    >
    <fx:Script>
        <![CDATA[
…
        [Bindable]
        [Inject(source="customerModel", required="true")]
        public var customerModel:CustomerModel; //Implement IModelArqManager
…

What I am trying to do is remove the "set isOnAddingMode" function from the 
ModuleSectionContent.as template, and the setters mapped in the 
CustomerView.mxml tag (we have about 20-25 binda variables similar to 
isOnAddingMode)
Can be done?
I have had relative success injecting the customerModel as an interface but 
binding is not working for me.

Any suggestion?

Thx.
Hiedra.
