Subject RE: XSP bug: can get generate() to skip elements using java 'if's
Date Tue, 10 Sep 2002 14:11:38 GMT
Michael,

Thanks for the tip. However, your tip makes the problem even more
interesting.

When the 'if' statement is true, the <xsp:attribute> does appear on the
toplevel element and the XML is valid (no more array bounds exception).

But when the 'if' statement is false, the <page> element isn't the top most,
it's emitted after the <content> element. E.g. <page> is a sibling of the
<content> element and the XML has _two_ top level elements, also invalid.
