Summary: mouse_ie.js null error, with possible patch

Initial Comment:
Background: 
Two objects on page (among others, but these seem to 
be the "offenders."
1) A single DynLayer with a single assigned 
eventListener for mouseover/mouseout, and using the 
glideTo method. Used to scroll a navigation menu up and 
down at top of page. 
2) A form button, disabled by default, with a "title" 
attribute set. No onmouseover trap defined for this 
button.

Symptom:
   On rapid mouseover over the button, javacript error in 
line 71 of mouse_ie.js. "null is not an object."
   Interesting that this only happened when the mouse 
was moving quickly. Never happened with slow mouse 
movement.

Lines 70-74 in mouse_ie.js --
----------------------------------
if (e.type=="mouseout" || e.type=="mouseover") {
  if (r && (r==src||src.isParentOf(r))) return; //fix for 
#15 (ie only)
  //if (r&&(r==src.parent||r.isChildOf(src.parent))) 
me.bubble=false;
  if (r&&(r==src.parent||r.isChildOf(src.parent))) 
me.bubble=false;
}
---------------------------------

I eliminated the problem, with no affect on correct 
functionality, by changing to this:

Lines 70-76 in mouse_ie.js --
---------------------------------
if (e.type=="mouseout" || e.type=="mouseover") {
  if (src != null) {	// error handler if src is null
    if (r && (r==src||src.isParentOf(r))) return; //fix for 
#15 (ie only)
    //if (r&&(r==src.parent||r.isChildOf(src.parent))) 
me.bubble=false;
    if (r&&(r==src.parent||r.isChildOf(src.parent))) 
me.bubble=false;
  }
}
--------------------------------

May not be the best fix, but it worked for this strange 
error. I searched and searched, and never could find 
WHY this error was occurring with a form button that is 
in no way using the DynAPI.

I was experiencing a bug in IE 6 where simply moving the
mouse around would random generate the above error in teh
same code.

This error occurs even when the full extent of you code is
to load the libraries (I.E. no layers created, no event
handlers added.. just load the api and library)

Adding the above mentions fix (checking for src!=null b4
doing stuff to src) fixes this and breaks nothing else as
far as i can tell.

I tested in IE 6 with the mouse event and drag event examples

Could someone please add this fix and post to the cvs.

2 years is long enough for this one imho.

cheers

[Andrew G. <an...@ph...>]

I've closed this bug. The patch was actually applied by Raymond quite a 
long time ago.
His CVS comment was:
 revision 1.7
 date: 2003/09/14 14:36:00;  author: xwisdom;  state: Exp;  lines: +2 -3
 Patch for dynapi.api.MouseEvent bug
 submitted by Peter Romianowski updated by Raymond

I guess there are probably other items in the bug list that should be 
closed.

Thanks Doug for raising this one.
If you find any more like this, please let us know :-)


Andrew.

Re: [Dynapi-Dev] [ dynapi-Bugs-840767 ] mouse_ie.js null error, with possible patch

[Leif W <war...@us...>]

Thanks Doug for pinging this.  If there are any other things you're 
wondering why no one responded to for 2-3 years, feel free to ping them 
too.  One at a time we can get them all.  Thanks for looking into this 
one too, Andrew.  You beat me to it.  :p  I too was looking at this.  I 
did pull a fresh CVS but did not look at the previous commit messages. 
I still want to test it just to make sure I understand it and verify 
that it's still fixed.

On a related note, since pushing this message through to the Dev list, I 
was thinking again.  Should I let all these tracker notifications flood 
the dev list or make a new list?  Well I decided to make a new list for 
that, so I have been setting up a list specifically to receive all the 
tracker messages from now on.  That should be read-only, whereas this 
dev list is where any subsequent discussions can take place.  I believe 
I mentioned something about this way back on the admin list, no replies. 
:p  Anyways it's how MinGW is doing it, and that seems to work well 
enough.

BTW: If anyone wants to ping in a real-time chat setting, pop on to IRC 
/server irc.freenode.net and /join #dynapi .  I leave myself idling in 
there.  Sometimes I am away and my system might crash (or someone else 
powers off), and I may or may not see a message in the logs when I next 
connect.  But generally I am on there and check the window a few times 
an hour.  If I disconnect without responding, there's the chance I miss 
a message, so you can leave a system message if it's critical.  So far 
no one but me has ever been there when I was there, so whoever is first 
will get a +v.  :p  Gaim is a nifty multi-IM (including IRC) and 
multi-OS client (including Linux & Windows), if you need a simple IRC 
client, otherwise mIRC is available for free usage in Windows.

Re: [Dynapi-Dev] [ dynapi-Bugs-840767 ] mouse_ie.js null error, with possible patch

[<do...@cr...>]

Hrm.. well the bug still exists in the production code.
This is not a small bug either, as it very consistant in producing said error
on ie 6 no matter what you are coding.

Can we publish a new production version then? maybe we can do a small push to
varify the current cvs version for publishing?

Hi Doug,

I was planning to look at it with IE6 today.  I spent yesterday setting 
up the new list, fiddling with the mailing list and trackers.

But, I'm unsure how to produce the bug?  Is it a specific library that 
causes the problem?  I can of course load them all and comment out one 
at a time, but it'd save time if I knew exactly what to load.  ;-) 
Also, it really occurs just with "the" library loaded and zipping the 
mouse arround quickly?  Do I need to test any other conditions?  DynAPI 
documents, layers, event handlers or html forms and so on?

Re: [Dynapi-Dev] [ dynapi-Bugs-840767 ] mouse_ie.js null error, with possible patch

[<do...@cr...>]

dynapi.library.setPath('/dynapi/');
dynapi.library.include('dynapi.library');
dynapi.library.include('dynapi.api');

That's it that's all.. you don't even have to instantiate any layers.

just move the mouse around a bunch fast, slow, medium whatever and you will
get the error. The only common denominator is that the mouse has to be moving
to produce the error.

Ahh, ok, I was looking at the CVS version, and it really is fixed.

In the production, you can even omit the 'dynapi.library' include.
All it takes is the 'dynapi.api' include to reproduce.

Yeah, please try the CVS.  Maybe we can make a beta2 release from 
current CVS and test that?  Would that be helpful?  I realize that any 
mention of CVS may deter some people from attempting to install CVS 
software and pull down a copy.  In Windows with TortoiseCVS it has been 
fairly painless for me.

Anyways, there's still stuff that may be broken, but I personally don't 
know them all.  So if anyone has a bug that has sat in the database and 
isn't fixed in CVS or the bug report is still open, then please ping us 
again.  Even just a message to the dev list with the bug numbers and a 
note to check it is helpful.  There's so many old ones, it's hard to 
know what should get priority at this point.  One at a time we can close 
them and hopefully get back to a mostly-closed state and make a new 
production release.

Re: [Dynapi-Dev] [ dynapi-Bugs-840767 ] mouse_ie.js null error, with possible patch

[Andrew G. <an...@ph...>]

I think that a beta2 release would be an excellent move.

Doug, I didn't realize that you where using beta1. I thought that since 
it was fixed in CVS that was all that mattered. Sorry.

The beta1 examples are online at 
http://dynapi.sourceforge.net/releases/dynapi-3.0.0-beta1/docs/docs/examples.html. 
Could you take a look and see if any of them cause the problem?  I've 
gone through a number of them with IE6 but I haven't been able to 
generate that particular error.  I did see quite a few other errors 
though. :-(

Re: [Dynapi-Dev] [ dynapi-Bugs-840767 ] mouse_ie.js null error, with possible patch

[<do...@cr...>]

I always use the production version downloadable from the front page as tis is
what any client will be evaluating.

Ug.. more bugs you say? I've been working in vbscript and VB and sql for so
long that i think it will be a nice break to dive into some js again.

I am working 9-5, however, I will put asside an hour or so of my gaming time
in the evenings to test and bughunt.

I would like to get the current cvs packed up and delivered as the current
production version on the front page soonest, like say, Aug 7th? (for some
reason i've started hating deadlines far less than I used to..)

To the lurkers: Please let us know you are out there.. even if you do not have
time to help with the current beta push, It would make me feel better knowing
that you guys ares till out there to help if we get in a bad bind with a
particular bug :-)

cheers

Summary: mouse_ie.js null error, with possible patch

Initial Comment:
Background: 
Two objects on page (among others, but these seem to 
be the "offenders."
1) A single DynLayer with a single assigned 
eventListener for mouseover/mouseout, and using the 
glideTo method. Used to scroll a navigation menu up and 
down at top of page. 
2) A form button, disabled by default, with a "title" 
attribute set. No onmouseover trap defined for this 
button.

Symptom:
   On rapid mouseover over the button, javacript error in 
line 71 of mouse_ie.js. "null is not an object."
   Interesting that this only happened when the mouse 
was moving quickly. Never happened with slow mouse 
movement.

Lines 70-74 in mouse_ie.js --
----------------------------------
if (e.type=="mouseout" || e.type=="mouseover") {
  if (r && (r==src||src.isParentOf(r))) return; //fix for 
#15 (ie only)
  //if (r&&(r==src.parent||r.isChildOf(src.parent))) 
me.bubble=false;
  if (r&&(r==src.parent||r.isChildOf(src.parent))) 
me.bubble=false;
}
---------------------------------

I eliminated the problem, with no affect on correct 
functionality, by changing to this:

Lines 70-76 in mouse_ie.js --
---------------------------------
if (e.type=="mouseout" || e.type=="mouseover") {
  if (src != null) {	// error handler if src is null
    if (r && (r==src||src.isParentOf(r))) return; //fix for 
#15 (ie only)
    //if (r&&(r==src.parent||r.isChildOf(src.parent))) 
me.bubble=false;
    if (r&&(r==src.parent||r.isChildOf(src.parent))) 
me.bubble=false;
  }
}
--------------------------------

May not be the best fix, but it worked for this strange 
error. I searched and searched, and never could find 
WHY this error was occurring with a form button that is 
in no way using the DynAPI.

The bug has been verified and a fix for the bug has been 
implemented.  The fix should be available in CVS as well as the 
next official release of the DynAPI.

I was experiencing a bug in IE 6 where simply moving the
mouse around would random generate the above error in teh
same code.

This error occurs even when the full extent of you code is
to load the libraries (I.E. no layers created, no event
handlers added.. just load the api and library)

Adding the above mentions fix (checking for src!=null b4
doing stuff to src) fixes this and breaks nothing else as
far as i can tell.

I tested in IE 6 with the mouse event and drag event examples

Could someone please add this fix and post to the cvs.

2 years is long enough for this one imho.

cheers
