The problem is that you end up having two identically named methods that return
different types. How is the compiler supposed to know which one to use? I had this
same problem myself for a while, because you are right that is what seems to follow
JavaBean specs. But your solution is exactly what you should do, you are still
following spec because you do have a getter method with the correct name. You just
also have an additional getter method to return one within the List. I think this
answers your question.

First, sorry for the long posting - it shorter than a few, but not many :).
I've read a number of very good postings on the list on how to handle
indexed properties using the "having a bit of a problem determining what the
corresponding getter/setter
names should be.
The problem is naming of the getter for my list of line items. At first I
had the following signatures
// First to get and set the entire list
public List getCurrLineItems() ...
public void setCurrLineItems(List lineItems) ...
// Next to get and set individual indexed items in the list
public LineItem getCurrLineItems(int liDex) ...
public void setCurrLineItems(int liDex, LineItem lineItem) ...
With the indexed getter/setters as above, it does not work. However, if I
name them differently from the List getter/setters they work (for example
names then getCurrentLineItems and setCurrentLineItems instead of
getCurrLineItems and setCurrLineItems). This appears to be contrary to all
of the examples I can find and the JavaBeans spec. Before proceeding I want
to clear this up.
With the matching names for indexed properties I could not get my JSP page
to see the line items. I tried the "logic:iterate", "nested:iterate" and
"logic-el:iterate" variations of the Struts iterate tag. I also tried using
a JSTL "
Existing Line Items

key="formLineItemsForm.status"/>

property="currLineItems" indexId="mpDex">
property="deleteXMP[${mpDex}]" value="true" title="Check to delete and press

property="name" size="24" maxlength="24" indexed="true"/>
indexed="true">
labelProperty="name"/>
size="1" maxlength="2" indexed="true" />
value="1" indexed="true"/> property="status_id" value="2" indexed="true"/>
