Hi Lou,
The <html> class was modified a while back and the attributes have changed. Once Henry's fix is applied, you also need to change the app to: 


<canvas >

   <include href="extensions/html.lzx"/>
<class name="browser" extends="window" resizable="true" bgcolor="silver"> 

      <edittext name="txt" text="http://openlaszlo.org/"; width="300"/>
<button x="310" onclick="parent.htmlview.setSrc(parent.txt.getText()); parent.htmlview.setAttribute('visible', true)"> 

      Load

      </button>

      <html name="htmlview"

            widthoffset="-19"

            heightoffset="74"

            xoffset="7"

            yoffset="53"/>

   </class>

   <browser width="500" height="500" x="10" y="10"/>

</canvas>
However, this example is still a bit wonky. The "real" version to use is http://localhost:8080/trunk/lps/components/extensions/test/html.lzx?lzr=dhtml. It still has issues in swf.
In Chapter 9 Introduction to Text and Fonts, Example 9.6. The <html> tag: 



<canvas >

   <include href="extensions/html.lzx"/>
<class name="browser" extends="window" resizable="true" bgcolor="silver">
<edittext name="txt" text=" http://openlaszlo.org/"; width="300"/>
<button x="310" onclick="parent.htmlview.setSrc(parent.txt.getText()); parent.htmlview.setAttribute('visible', true)"> 

      Load

      </button>

      <html name="htmlview"

            width="${parent.width - 19}"

            height="${parent.height - 74}"

            x="${parent.x + 7}"

            y="${parent.y + 53}"/>

   </class>

   <browser width="500" height="500" x="10" y="10"/>

</canvas>



The compiler complains:
extensions/html.lzx:46:56: In element 'class' attribute 'xoffset' with type 'number' is overriding parent class attribute with same name but different type: numberExpression
extensions/html.lzx:47:56: In element 'class' attribute 'yoffset' with type 'number' is overriding parent class attribute with same name but different type: numberExpression

Any ideas?



Thanks,



Lou
