Hi Ean,
Below is the modification of the example you have given as per what I
propose.
Groovy:
def user = dispatcher.runSync("getSpecialUser", [])
context.userDetails = { user };
FTL:
<table>
<#if(userDetails != null)>
<tr>
<td>
<span class="firstname">$user.firstName</span>
<span class="lastname">$user.lastName</span>
</td>
</tr>
<else>
<tr>
<td>
<span class="notperson">User doesn't exists</span>
</td>
</tr>
<#if>
</table>
