T5: Flash persistence strategy

[Joel Wiegman]

Greetings all,

I attempted to expand upon the T5 "FlashDemo" found here:

http://svn.apache.org/viewvc/tapestry/tapestry5/trunk/tapestry-core/src/
test/app1/WEB-INF/

I'm attempting to write a "Messages" component that can be included
anywhere and show a group of messages to a user.

But for some reason the messages are persisting past a single-page
rendering, despite using the new "flash" persistence strategy (which I'm
assuming is available in 5.0.4).  Can anyone spot the flaw?  Thanks!

"Messages" component:

@Meta("tapestry.persistence-strategy=flash")
public class Messages {

    @Persist
    private List<String> messages = new ArrayList<String>();

    @Persist
    private String currentMessage;
    
    public List<String> getMessages()
    {
        return messages;
    }
        
    public void addMessage(String message) {
        messages.add(message);
    }
    
    public String getCurrentMessage() {
        return currentMessage;
    }
    
    public void setCurrentMessage(String currentMessage) {
        this.currentMessage = currentMessage;
    }
    
}

"Messages" template:

<t:if test="messages"
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
        <ul>
                <li t:type="loop" source="messages"
value="currentMessage">
                        ${currentMessage}
                </li>
        </ul>
</t:if>
