Getting NullPointerException when trying to edit JSP pages: [message #141091]

I am using the eclipse 3.1 + WTP 0.7 bundle.

I have added a <%@ taglib uri="" prefix="" %> statement to a JSP page,
then when I edit the page one of two things happen:

(and I know this sounds funny!)
1. If I type in the JSP, the characters are added *backwards*. E.G.
"<html" is rendered as "<lmth" in the editor.
2. If I try and delete/paste otherwise edit any text, a
NullPointerException is thrown and in the logs I find the following
stack trace:

"!ENTRY org.eclipse.ui 4 4 2005-09-28 15:21:17.695
!MESSAGE "Delete" did not complete normally. Please see the log for
more information.

Any ideas?

What backwards? How can that happen?
I didn't believe it myself until I saw it, in previous posts/bugzilla's.=

I has been fixed in 0.7.1, officially released just today,
See
http://download.eclipse.org/webtools/downloads/drops/M-0.7.1 -20050927072=
0/

I'm not sure about your other problem.
