Tapestry 4 beta 5: Persistent property problem on home page
Platform: Tapestry 4 beta 5
Problem Description:
Persistent properties on a page declared as the home-page are not persisted on the first set, but revert back to their initial values.
On subsequent sets the properties are persisted.
If the page is not declared as home, the first persistent property set works as expected.
Sample code is available; questions, comments, solutions are welcomed.

Re: Tapestry 4 beta 5: Persistent property problem on home page
Posted by Joey Solis <ta...@formos.com>.
I found out the cause of the persistence issue. In my code I refer to my home page with its actual page name -- getPage("Simple"), which seems to create a new instance of the page and re-initialize the property. If I get the page using getPage("Home"), it works fine as there is no re-initialization.
Is there a work around to be able to refer to the "Home" page with its actual page name? Otherwise, I could keep on referring to it as Home or rename it Home.
Thanks,
Joey
Here's my CODE:
/** Simple / Home page **/
public abstract class Simple extends BaseSimplePage implements PageBeginRenderListener{
@Persist
public abstract String getUserName();
public abstract void setUserName(String s);
public void loadAnotherPage(){
System.out.println("Load another page...");
IPage page = getRequestCycle().getPage("AnotherPage");
getRequestCycle().activate(page);
}
public void pageBeginRender(PageEvent arg0) {
System.out.println("Home.pageBeginRender before set: " + getUserName());
setUserName("New");
System.out.println("Home.pageBeginRender after set: " + getUserName());
}
public void finishLoad(IRequestCycle arg0, IPageLoader arg1, IComponentSpecification arg2) {
System.out.println("Home.finishLoad");
setUserName("Initial");
super.finishLoad(arg0, arg1, arg2);
}
}
/** AnotherPage **/
public abstract class AnotherPage extends BaseSimplePage{
private static final Logger LOG = Logger.getLogger(AnotherPage.class);
public void loadHome(){
System.out.println("AnotherPage, loading Home page...");
// Simple page is the "Home" page.
// If it is referred to as "Simple", a new instance is created and the property is re-initialized.
Simple page = (Simple)getRequestCycle().getPage("Simple");
// This does not create a new instance of the Simple page.
// Simple page = (Simple)getRequestCycle().getPage("Home");
getRequestCycle().activate(page);
// Is there a way to set up a "Home" page not named Home.* and be accessed with cycle.getPage("NotHomeName")?
// (without having its property reinitialized)
}
}
CONSOLE OUTPUT:
Home.finishLoad
Home.pageBeginRender before set: Initial
Home.pageBeginRender after set: New
Load another page...
AnotherPage, loading Home page...
Home.finishLoad
Home.pageBeginRender before set: Initial
Home.pageBeginRender after set: New
