Yea I already have a scenario like where it works, but I have List Object,
which contains a List of Data Objects
di3List is a List in the request scope, which is holding Lists of Data. If
di3List is returning a List of Lists, how do I get access to the Data
Objects
<logic:iterate id="list" name="di3List" scope="request" >
HOT
<logic:iterate id="data" collection="<%=list%>"
type="sandbox.struts.iteratelist.Dictionary">
<li><bean:write name="data" property="word"/> - <bean:write
name="data" property="definition"/></li>
</logic:iterate>
</logic:iterate>
The code above is giving the following error. I understand why I am getting
this error, but how do I access the Data Objects in the inner list?
