Re: [WDSCI-L] WebFacing and dying IE sessions






Hi all!

Seems as if we fixed our problem with dying IE sessions. Problem was home
made.

At least two years ago (before my time here) a developer added a tiny
JavaScript to a lot of DSPFs that was supposed to call a user defined
JavaScript function on mouseover events (a fancy tooltip). Unfortunately
this feature wasn't well received by our clients for some reason and so
the calling code was commented out in the DSPFs and the exectution script
was totally removed.

What noone noticed for 2 years was the fact that the DDS parser *IGNORES*
comments in certain DDS extensions. So the calling code was still active
while the actual JavaScript function was no longer available - hence a
object not found error was fired every time you hoovered your mouse over
given fields.

People who heavily used their mouse angried IE the longer they unknowingly
genereted scripting errors ("show scripting errors" is disabled by
default).

My IE naturally shows scripting errors but unfortunately I rarely use the
mouse in a Webfacing session so you maybe can imagine how long it took me
to nailed that problem down.

Mit freundlichen Grüßen
