I'm assuming you mean in the Containing Page? I tried switching it to
onActivate instead of beginRender and in this case the afterRender
method throws a NoSuchElementException when trying to pop the Object
from the Environment, code as below:
//@BeginRender
public void onActivate(){
debug("Loaded ViewProductTab and SubPageId = " + this.id);
env.push(PageId.class, id);
}
@AfterRender
public void popPageId(){
this.id = env.pop(PageId.class);
}
After considering Robert's suggestions with onPrepareForSubmit, I was
able to hack a solution, at least it feels hackish. I found out that
when trying to push the @Environmental PageId in the SubPage back into
the Environment, it is already lost. However, the onPrepare method it
still exists, so I can assign it to a @Persist field in the page and
then push that back into the environment at onPrepareForSubmit method.
This seems a bit cheap to me, but its simple and it works.
Honestly, this is confusing because documentation says that
onPrepareForSubmit gets fired before onPrepare does? Id is available in
onPrepare but not onPrepareForSubmit after a form submission. Code below:
@Environmental
private PageId id;
@Persist
private PageId heldId;
@Inject
private Environment env;
public void onPrepare(){
prod = (Product) pdao.read(id.getId());
heldId = id;
debug("In onPrepare of DetailsTab in partner package. Loaded
Product ::"+prod+":: from DB");
}
void onPrepareForSubmit(){
debug("\n\n\n In onPrepareForSubmit \n\n\n");
env.push(PageId.class, heldId); //push back
debug("\n\n\n pushed PageId onto env \n\n\n");
}

Spoke a little too soon. One minor thing remains in some of the
sub-subPages related to the Environmental stuff. Passing the PageId
Object from the containing page to the sub-page through the
environment works out okay, but when I submit forms on any of the
sub-pages I get an exception stating the PageId object isn't in the
environment.
Have you tried adding the pageId to the Environment on onActivate()
instead of beginRender()?
