Dave,
It's about more than that. You can send some amount of data - couldn't tell
you how much. The important thing is that the response has not been
committed. It sounds to me as if Pauls' response has been committed (due to
sufficient output having been sent).
Essentially, you want to check right up front if you need to do a redirect.
Paul, why did you move your redirect into a tile? If you need some pages
not to check for your userData object, why not just have a second layout?
<!-- Will output document head and such - first order of business in body is
to determine if "userData"
is present. If not, it redirects. If it is, it invokes tiles:insert for
the "page" attribute. -->
<definition name="secure.root" ....>
<put name="page" value="..." />
</definition>
<!-- This one does not have the check -->
<definition name="insecure.root" ...>
<put name="page" value="..." />
</definition>
<!-- Here we use the above. We could break the page
<definition name="secure.home" extends="secure.root">
<put name="page" value="..." />
</definition>
<definition name="insecure.login" extends="insecure.root">
<put name="page" value="..." />
</definition>
You'd be better served to use a filter to determine if a user is logged in
and send them to your login page if they aren't, but the above should help
you out, I think, if you're already heavily invested in this direction.
Regards,
Eddie

Any ideas?
Could it be because a redirect only works if no data has been sent to the
browser yet? (But I thought I saw an HTML comment before the redirect that
works, so maybe that's not the right trail to head down.)
