OK. The template it's happening on is shown below. WM is reporting:

2003-04-03 02:42:48 WebMacro:servlet	WARNING	Ignition encountered an error 
while executing a template:
StreamTemplate:jndi:/localhost/ignition/WEB- 
INF/templates/system/moduleHelp.wmt: org.webmacro.PropertyException: 
Attempt to invoke method public static int 
org.webmacro.servlet.ListUtil.size(java.util.List) on object 
org.webmacro.servlet.ListUtil raised an exception: 
java.lang.NullPointerException
java.lang.NullPointerException at jndi:/localhost/ignition/WEB- 
INF/templates/system/moduleHelp.wmt:29.7

Here's the (work in progress) template... there is no call to $List.size() 
anywhere near line 29. BUT there -is-a call to it on line 29 of 
system/helpMacros.wmt - so it looks like it is the incorrect filename being 
reported.

#include as macro "system/helpMacros.wmt"
#include "includes/header.wmt"

#if (!$ignitionHelp.Module)
  #set $mod = "default module"
#else
  #set $mod = "module $ignitionHelp.Module"
#end
<h1>Ignition Help for $mod</h1>

<p>
You can view help from the other modules:
#foreach $moduleName in $ignitionHelp.ModuleNames
  #if ($moduleName != $ignitionHelp.Module)
    #set $action = $Ignition.newAction("ignitionHelp")
    #set $action.Module = $moduleName
    #set $modMenuName = $moduleName
    #if ($moduleName == "")
       #set $modMenuName = "DEFAULT"
    #end
    <a href="$Ignition.execute([$action])">$modMenuName</a>
  #end
#end
</p>

          Below is a list of the actions available from templates in the

          you can insert the following into your templates:
            #text
          <pre>
          #set $action = $Ignition.newAction( "actionNameHere")
          #set $action.ParamNameHere = "ParamValueHere"
          &lt;a href="$Ignition.execute([$action])"&gt;Link to 
action&lt;/a&gt;

The following helpers are available in your templates, for this module. 
They can be accessed
like this:
  #text
<pre>
&lt;b&gt;The value is:&lt;b&gt; $HelperNameHere.PropertyNameHere
$HelperNameHere.methodName("someParam")
</pre>
  #end

<p>
$action.Name -

#else
  There are no helpers in this module.
