Re: T5 Complex NPE in org.apache.tapestry.internal.util.Base64InputStream
I have not fixed this in my application yet. I think there is a way
to tell Acegi to use a custom redirect filter you would provide.
That's where you can intercept the request URL (that initiated the
login procedure) and modify it. So the modification would be to just
redirect to the page, stripping off the form variables and such. (Or
if you are really good, you could strip off only the variables
references that were breaking the app.)
In the interim, I think there is a way in the Acegi XML to forward
back to a single URL, like the start page, instead of redirecting you
to the original request.
That would at least keep users from thinking the app is broken. =)
If someone on the list has implemented this already, please share if you can!
I'm not sure when I'll have time to fix this issue.
