backing bean getting created/invoked twice?
I have a page which takes a request-scoped backing bean. I noticed that when
the page is loaded the backing bean gets created twice, then when the form
is submitted (using an h:commandButton with attached action) the bean gets
created twice again and the backing method gets called twice. We're using
myfaces, so we have the 1.2.0 myfaces JSF api and implementation on the
classpath (Sun's reference implementation isn't part of the war).
I'm pretty much at a loss on this, so any help would be great. Thanks.

If your navigation rules imply a <redirect/> and you don't have redirect
tracker manager enabled (part of tomahawk), you woul indeed get 2
request from browser and 2 invocation of backing beans:
Browser: submit form (request 1)
JSF: Received, apply request values (eventually create on demand request
scoped beans), validate, execut action, get navigation rule, send a
"redirect" to new location to browser
Browser, gets the redirect rule, request the new location from JSF
(request 2)
JSF: receive a get, create view, eventually create request scoped beans
on demand, render response.
