Re: SDK - meta_data in SAP UI5 component

I don't have a full component, I've tried only with an skeleton and debuging Javascript, I can't see a meta_data object like in other custom components.

My code:

Contribution.ztl

class com.sap.sample.ui5.Sample extends Component {  String getSelectedValue(){*  return this.selectedValue;  *}
}

Contribution.xml

<?xml version="1.0" encoding="UTF-8"?><sdkExtension  xmlns="http://www.sap.com/bi/zen/sdk"  id="com.sap.sample.ui5"  title="Design Studio SDK Extension Sample SAPUI5"  version="1.0"  vendor="SAP">  <group  id="sapui5"  title="SAP UI5 Custom Components"/>  <component  id="sample"  title="Sample"  icon="res/icon.png"  handlerType="sapui5"  databound="true"  group="sapui5">  <jsInclude>res/js/components.js</jsInclude>  <property  id="selectedValue"  title="selectedValue"  type="String"  visible="false"/>  <property  id="onChange"  title="On Change"  type="ScriptText"  group="Events"/>  <initialization>  <defaultValue property="WIDTH">300</defaultValue>  <defaultValue property="HEIGHT">30</defaultValue>  </initialization>  </component></sdkExtension>

Component.js

sap.ui.commons.Sample.extend("com.sap.sample.ui5.ComboBox", {  metadata : {        properties : {            "metadata": null,            "selectedValue" : null      }  },  setSelectedValue : function(value) {       this.selectedValue = value;  },  getSelectedValue : function() {       return this.selectedValue;  },  setMetadata : function(value) {       this.metadata = value;  },  getMetadata : function() {       return this.metadata;  },  renderer : {  },  initDesignStudio: function() {  try {       var that = this;       // access to metadata???       this.attachChange(function() {       that.setSelectedValue('Hello');       that.fireDesignStudioPropertiesChanged( [ "selectedValue" ]);       that.fireDesignStudioEvent("onchange");  });  }  catch (e) {  // TODO: handle exception  }  },  renderer: {}
});

Thanks!
