Status: RESOLVED EXPIRED

(Core :: DOM: Core & HTML, defect)

User-Agent:       Mozilla/5.0 (X11; U; Linux i586; en-US; rv:1.4.2) Gecko/20040220

I have an application that uses several frames. One frame has a kind of status
area that periodically refreshes itself, controlled by Javascript. In another
frame there's a text input area. When I write a longer text into the input field
while the other frame refreshes, input characters occasionally loose their
position and end up right of the input cursor, causing them to be scrolled right
along with entering more text.
This effect does not occur with MS IE 6.0!

Reproducible: Always
Steps to Reproduce:
1. Enetr text in one input ares while another frame refreshes itself.

Actual Results:  
Occasionally characters appear right from the input cursor.

Expected Results:  
Characters should not move along with inputting text

I'm sorry, but it seems I was wrong: The application seems to use "server push"
technology to update the frame, not a client-side Javascript timer.
Unfortunately the software is proprietary, so I cannot really provide any code
from it.
Maybe if someone has some server-push code at hand, he or she could try to
create a multi-frame document, where one frame is periodically refreshed while
theres some input in a textarea inside another frame. If nobody can do it, I
could try it myself, but I never wrote such code before.

The bug is still current, even for Firefox. As it turned out the scenario is
like follows: An application using frames and javascript is running in one tab,
and I'm entering text to some input area of another tab in the same window. Then
occasionally order of letters gets wild. usually one character is right from the
cursor and is being shifted on while more text is eneterd.
I cannot provide the source code, because it's in an embedded device, and it's
using conditional Javascript depending in the browser and Java, too. When trying
to "mirror" the server, it bails out very early.
Anyway I can tell you the following:
The pages use "<meta http-equiv="Pragma" CONTENT="no-cache"> and Javascript do
do things like this:

function status()
{
   ...
   setTimeout("status()", 500);
   ...
}

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
