Description

Main application:

<js:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:js="library://ns.apache.org/flexjs/basic"
xmlns:local="*">
<js:valuesImpl>
<js:SimpleCSSValuesImpl/>
</js:valuesImpl>
<js:initialView>
<local:ViewSubclass/>
</js:initialView>
</js:Application>

ViewSubclass.mxml

<js:View xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:js="library://ns.apache.org/flexjs/basic">
<js:Label text="Hello World"/>
</js:View>

The following error is thrown

"TypeError: Cannot read property 'apply' of undefined\n at ViewSubclass.get (file:///Users/joshtynjala/Development/NextGenAS/examples/FlexJSBasics/bin/js-debug/ViewSubclass.js:54:65)\n at ViewSubclass.org.apache.flex.core.ContainerBase.addedToParent (file:///Users/joshtynjala/Development/NextGenAS/examples/FlexJSBasics/bin/js-debug/org/apache/flex/core/ContainerBase.js:173:99)\n at FlexJSBasics.org.apache.flex.core.Application.addElement (file:///Users/joshtynjala/Development/NextGenAS/examples/FlexJSBasics/bin/js-debug/org/apache/flex/core/Application.js:115:5)\n at FlexJSBasics.org.apache.flex.core.Application.initialize (file:///Users/joshtynjala/Development/NextGenAS/examples/FlexJSBasics/bin/js-debug/org/apache/flex/core/Application.js:265:8)\n at FlexJSBasics.org.apache.flex.core.Application.start (file:///Users/joshtynjala/Development/NextGenAS/examples/FlexJSBasics/bin/js-debug/org/apache/flex/core/Application.js:236:10)\n at file:///Users/joshtynjala/Development/NextGenAS/examples/FlexJSBasics/bin/js-debug/index.html:89:22"

The error happens at the following line in the generated ViewSubclass.js:

var arr = ViewSubclass.superClass_.get__MXMLDescriptor.apply(this);

Perhaps the superClass_ doesn't have the getter, and it's further up the inheritance chain?
