Hi,
I just found out that jx:set does not quite behave like I expected. Please consider
the following JXTemplate snippets:
<!-- 1 -->
<element attr="${request.getAttribute('foo')}"/>
<!-- 2 -->
<jx:set var="foo" value="${request.getAttribute('foo')}"/>
<element attr="${foo}"/>
1 and 2 should be equivalent, shouldn't they? Everything is fine as long as the
request attribute 'foo' is available. However, if this is not the case (i.e.
request.getAttribute('foo') evaluates to null) then the first snippet is transformed
into
<element attr="" />
while the latter is transformed into
<element attr="[Lorg.w3c.dom.Node;@6e3dee" />
Am I doing something wrong? Or is this a bug? I couldn't find anything about it in the
mail archives.
I could imagine that the JXTemplateGenerator uses an empty DOM-Node as some kind of
NullObject-Pattern. This would work inside xml element nodes (i.e.
<element>${foo}</element> works fine in the second example), but would fail inside
attributes.
Any ideas?
Regards,
Jan Harms
P.S. I use cocoon 2.1.4.
