In Chapter 33. Extending Classes, example 33.8:
<canvas height="50">
<class name="htmlText">
<attribute name="text" type="html"/>
<text resize="true" text="${parent.text}"/>
</class>
<simplelayout/>
<htmlText>
<b>bold</b> text declared here with
<a href="http://www.openlaszlo.org"><i>anchor</i></a>
</htmlText>
<htmlText text="<b>bold</b> text set here"/>
</canvas>
to which the compiler says:
class-inheritance-$12.lzx:9:13: The tag 'b' cannot be used as a child
of htmlText
class-inheritance-$12.lzx:9:13: The tag 'a' cannot be used as a child
of htmlText
I can't tell what's going on here, since the example seems to work.
