I have made further progress.
To me it looks like jstl issue rather than display tag.
Some how I can not use ${variablename} in display tag.
cout works. but i can not c out inside title.
so following code works - but i am not able to get title. I have hardcoded
title as a. Any help is apprecited
<display:table uid="item" name="items">
<c:forEach var="cl" items="${item.innerBeans }" varStatus="index1">
<display:column title="a"><c:out value="${item.innerBeans [
index1.index].currYearExpenditure}"/></display:column>
</c:forEach>
</display:table>

Thanks Ed for the response.
This assumtion is correct - that all
your bean2 objects have the same number of bean1 beans in their Lists
and they are present in the same order.
I tried your example exactly and it does not work for me.
But I do not get value and in title i get innerBeans[${index}].title
display.
I tried index.index, c.title every thing. But it displays the text as put
in title and property is blank.
The progress i made from my code is it adds three columns, as outerbean as
three elements of inner bean.
