justinmclean opened a new issue #73: Accidentally adding bead to style causes null pointer exception when compiling 
URL: https://github.com/apache/royale-asjs/issues/73
 
 
   Someone may run into this issue and documenting it may help them.
   
   Example code:
   ```
   <?xml version="1.0" encoding="utf-8"?>
   <js:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
                  xmlns:js="library://ns.apache.org/royale/basic">
      <js:valuesImpl>
          <js:SimpleCSSValuesImpl/>
      </js:valuesImpl>
   
      <js:initialView>
          <js:View width="200" height="200">
              <js:Container>
                  <js:style>
                      <js:VerticalLayout />
                      <js:SimpleCSSStyles padding="20" margin="50" backgroundColor="red" />
                  </js:style>
                  <js:Label text="Hello" />
                  <js:Label text="World" />
              </js:Container>
          </js:View>
      </js:initialView>
   </js:Application>
   ```
   
   May not be unreasonable to think that VerticalLayout is a style rather than a bead and make this error.
   
   Will on compilation give the rather unhelpful error below with no stack trace or other information.
   ```
   Error: Unexpected exception 'java.lang.NullPointerException'.
   Unexpected exception 'java.lang.NullPointerException'.
   ```
