Question

I just tried to upgrade to Twiki 4.2 - everything seems to be OK so far - but...

I had inserted:

%INCLUDE{"%SYSTEMWEB%.HierarchicalNavigation" section="all"}%

into my sidebar. Now the structured list does not seem to work any longer. I always get:

 IF{ "" else="" then=" * [[TWiki.][]]" }: Empty expression

    * WebHome 

instead of the child topic list.

Does anybody know why this might happen?

Answer

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

Did you edit this with RAW or wysiwyg. 4.2 switches to the wysiwyg editor by default. Did you try re-editing in raw?

Yes - I tried it both ways. I even did a clean Install in a virtual machine and then only inserted the above line with raw edit. It happened again. I thought I might have made a mistake because HierarchichalNavigation in the personal sidebar is such a nice feature I think and so more people should face the same problem... But I really cannot find anything I might have done wrong during installation - and - btw. everything else works fine. Any help would be very much appreciated.

I can confirm the bug. Tracked in Bugs:Item5405. And fixed.

If you want to use this before the next update of TWiki, copy these lines to the topic (replace existing STARTSECTION..ENDSECTIONs):

%STARTSECTION{name="all"}%<div class="twikiHierarchicalNavigation">
<ul>
%SEARCH{
"parent"
type="query"
topic="%BASETOPIC%"
web="%BASEWEB%"
nonoise="on"
format="<li class='twikiParentTopic'><img src='%ICONURL{parent_gray}%' width='16' height='16' alt='' border='0' /> [[$web.$parent][$parent]]</li>"
}%
<li class='twikiCurrentTopic' style='font-weight:bold;'><nop>%BASETOPIC%</li>%INCLUDE{"%TOPIC%" section="childlist"}%
</ul>
</div><!--/twikiHierarchicalNavigation-->%ENDSECTION{name="all"}%

%STARTSECTION{name="children"}%<div class="twikiHierarchicalNavigation">
<ul>%INCLUDE{"%TOPIC%" section="childlist"}%</ul>
</div><!--/twikiHierarchicalNavigation-->%ENDSECTION{name="children"}%</div>%ENDSECTION{name="children"}%

%STARTSECTION{name="childlist"}%%SEARCH{
"parent.name='%BASETOPIC%'"
web="%BASEWEB%"
type="query"
nonoise="on"
format="<li class='childTopic'><img src='%ICONURL{line_ur_gray}%' width='16' height='16' alt='' border='0' /> [[$web.$topic][$topic]]</li>"
}%%ENDSECTION{name="childlist"}%

I have used 2 new graphics, added to this topic. You can attach these to your TWiki.TWikiDocGraphics topic.
