Glad you found the solution. As you're obviously a good code hacker here's a tip...
It's always best to put code fragments in < raw>...< /raw> tags (under the "More v" button) so you can see the source and not have graphics and certain other code interpreted.
Nabble offer something better still in this support forum. Use this form of opening tag:
< raw class='xml' name='code'>
(Note: Throughout the text above, I have added a space after the opening < in tags in order to make them appear within the message.)
then your code appears like this:
<n.if.current_node.is_app>
<else><img src="/images/thread.png" width="20" height="18"/></else>
</n.if.current_node.is_app>
The line numbers and syntax highlighting make it far easier to describe the important features of your code to others and, if you use the "Plain text" link you'll find that, in most browsers, the code appears in a new window where it is easy to select, copy and paste.
