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>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:

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'

on class attribute", did you mean to use that?
text-tutorial-$6.lzx:13:35: found an unknown attribute named
"height" on element html, however there is an attribute named
"heightoffset" on class attribute", did you mean to use that?
text-tutorial-$6.lzx:13:35: found an unknown attribute named "x" on
element html, however there is an attribute named "xoffset" on class

text-tutorial-$6.lzx:13:35: found an unknown attribute named "y" on
element html, however there is an attribute named "yoffset" on class
attribute", did you mean to use that?
Any ideas?
Thanks,
Lou
