The anchor parameter in the url tag does not evaluate OGNL expression.

Suppose you have this:

<s:url var="showEmployee" action="ShowEmployee" anchor="%

{employee.lastName}">
<s:param name="id" value="employee.id"/>
</s:url>

Struts2 generates:

ShowEmployee.action?id=1234#%{employee.lastName}

The OGNL expression in the anchor attribute is rendered literally.
