T5: Page lifecycle and pageAttached()
Hi all,
I'm using 5.0.4, I have two pages, Page1 and Page2, similar to this:
Page1.html
<html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd" >
<head><title>Page 1</title></head>
<body>
<t:pagelink page="page2">Page 2</t:pagelink>
</body>
</html>
Page2.html
<html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd" >
<head><title>Page 2</title></head>
<body>
<t:pagelink page="page1">Page 1</t:pagelink>
</body>
</html>
where both pageAttached() and pageDetached() just log the call.
When Page1 is just loaded, the log is:
Page1.pageAttached
Page2.pageAttached
Page1.pageDetached
Page2.pageDetached
Why is Page2 attached to the request? If I have a menu with some pagelinks,
all of them are being attached and detached every call.
If this behavior is correct, where is the place to load database content to
show in a page? If the page has a form, onPrepare() does the work, but what
about a page with no form and no context? Is onActivate() the method I'm
looking for?
Thanks.

This behavior is correct.
Page2 is attach to the request because of the PageLink component.
The PageLink component (or rather, the LinkFactory service behind the
scenes) obtains an instance of Page2 so that it can fire the
"passivate" event on it.
