In that checking one of the variable is == null.
before that if statement add if (var == null) var ="";
for both variables and problem will go away.

> Nothing strange on line 80. Just a simple IF statement checking if a
string variable is equal to a particular string. I most certainly haven't
touched that code or any associated code in quite a while. Yet suddenly I
got this error. I also copied this app (as a .war) to somebody else's
machine, ran it there fine. Next day I was going to look at something on
that machine and I got the error again. I asked the owner of the machine
what had been changed but was told nothing (which I didn't believe). After
examinig the code I gave up on it because everything seemed ok. For the
heck of it, I checked the page again and it worked fine !?! (i.e. the Reload
action did it as has been reported before by others).
