In header.jsp there is the following code for splitting nav parameters:
<logic:iterate id="n" name="kkEng" property="nav" type="java.lang.String">
<%if (n!=null && n.split(";").length==2){%>
» <html:link page="<%=n.split(";")[1]%>"><%=n.split(";")[0]%></html:link>
<%}else{%>
» <bean:write name="n" filter="false"/>
<%}%>
</logic:iterate>
Using a semi colon as the split identifier can cause problems if you have HTML code in the string --for example, I use the HTML code for an apostrophe (#39;) in my name field and since HTML codes end with a semi colon, a false split occurs.. I think its risky to assume the nav string will never contain an intentional semi-colon.
