Guus, 

See the thread from before I cut and pasted below.
--------------------------------------------------------------

Sure thing - I already sent it but the list refused it due to its file size.
As an alternative, I'll put it up on my personal FTP space and anyone who
wants it can download it from there! :) 
Struts.jar with Form tag modifications: http://www.enfused.com/struts.jar

Thank you for responding so quickly as I was about to hit
my head against a wall! Perhaps you could attach that
working version you mentioned I could use? In the
meantime, I'm going to obtain the rest of the software I'll
need in order to compile Struts myself -- just in case. 
Thank you so much!

Subject: Problem upgrading from struts-1.0-b1 to struts-1.0


After upgrading from struts-1.0-b1 to struts-1.0 I keep getting a servlet
error with the message "can't remove attributes from request scope". This is
especially annoying because it occurs in the login JSP of my application and
thus it blocks my progress.
I checked the installation notes several times to see if I overlooked
something, but found nothing wrong.
Does anyone have a suggestion?
(In the mean while I'll just add the Struts source to my project and debug
through it.....)

Regards
Guus
