[GitHub] [royale-asjs] raudjcholo opened a new issue #843: Binding problem with currentState using Crux

[GitBox]

raudjcholo opened a new issue #843:
URL: https://github.com/apache/royale-asjs/issues/843


   I think there is a bug when we bind currentState with a model variable using 
Crux.
   
   Example:
   
   View:
   
   ```
   <?xml version="1.0" encoding="utf-8"?>
   <j:ApplicationResponsiveView xmlns:fx="http://ns.adobe.com/mxml/2009";
           xmlns:j="library://ns.apache.org/royale/jewel"
           xmlns:js="library://ns.apache.org/royale/basic"
           currentState="{securityModel.state}"
       >
       <fx:Script>
           <![CDATA[
   
               import com.iest.winplusweb.events.SecurityEvent;
               import com.iest.winplusweb.models.SecurityModel;
   
               [Bindable]
               [Inject(source="securityModel", required="true")]
               public var securityModel:SecurityModel;
   
               public function getTest():void
               {
                   var testEvent:SecurityEvent = new 
SecurityEvent(SecurityEvent.TEST_CURRENT_STATE);
                   dispatchEvent(testEvent);
               }
               ]]>
       </fx:Script>
   
        <j:states>
           <js:State name="start" />
           <js:State name="update" />
       </j:states>
   
       <j:beads>
           <js:SimpleStatesImpl/>
           <js:ViewDataBinding/>
       </j:beads>
   
      <j:VGroup width="400" gap="10">
               <j:HGroup>
                   <j:Button localId="btlanzar" text="Action"

                   <j:TextInput localId="TDebug" width="100"

               </j:HGroup>
           </j:VGroup>
   
   </j:ApplicationResponsiveView>
   ```
   
   Model:
   
   ```
   [Bindable]
       public class SecurityModel extends Model
       {
   
          public var state:String = "start";
   
           private static var _instance:SecurityModel;
           public static function get instance():SecurityModel{
               return _instance || (_instance = new SecurityModel());
           }
           
               
           /**

               super();
               if (_instance) {
                   trace('SecurityModel error');
                   throw new Error("singleton");
               }
               _instance = this;
           }        
      }
   ```
   
   Controller:
   ```
   public class SecurityController extends Controller {
   
           public function get model():SecurityModel {
               return _model as SecurityModel;
           }
   
           [Inject]
           public function setModel(value:SecurityModel):void {
               _model = value;
           }
   
           /**

           override public function set strand(value:IStrand):void {
               super.strand = value;
           }
   
             [EventHandler(event = "SecurityEvent.TEST_CURRENT_STATE", 
scope="global")]
           public function testCurrentState():void{
               model.state = "update";
           }
      }
   ```
