Help with passing data back to the backing bean using Seam's

[tonylmai]

Hello all,

Can someone help me to look through this piece of code in which I can't seem to pass a data back to the backing bean using Seam's EL. Perhaps the error is in my data model for the DataModelSelection.

I have a page that display quotes that belong to an account which belongs to a customer. A customer however may have many accounts.

Customer 1----* Account 1----*Quote

On my page, I have

<c:forEach var="acct" items="#{acctQuotes}">
 <rich:dataTable value="#{acct.quotes}" var="quote">
 <rich:column>
 <s:link value="ABC" action="#{wcQuotesMgr.viewNews(quote)}" />

wcQuotesMgr is

@Name("wcQuotesMgr")
public class QuotesManagerBean implements QuotesManager {
 @DataModel("acctQuotes")
 private List<PortfolioQuote> acctQuotes;

 @DataModelSelection("acctQuotes")
 @Out(required = false)
 private PortfolioQuote portfolioQuote;

 public String viewNews(Quote quote) {
 // quote is not passed correctly. It is always null here
 }

And finally PortfolioQuote is as followed:

public class PortfolioQuote implements Serializable {
 private static final long serialVersionUID = 1L;
 private Account account = null;

 @DataModel("quotes")
 private List<Quote> quotes = null;

 @DataModelSelection("quotes")
 @Out(required = false)
 private Quote quote;
...
}

Everytime the user clicked on the link to view news, wcQuotesMgr.viewNews is invoked with null passed in for parameter quote. How do I model this DataModel and/or DataModelSelection so that quote is passed accordingly?

Thanks for your help

Use page parameters instead of extended EL (extended el can work oddly inside iterative components)
