From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.8.1+) Gecko/20010323 BuildID: Mozilla 0.8.1+ autocomplete nightly First the page rendrs as meant to on NS6.1 but on this build and all of the nightlyies for the past three weeks the following occurs. Aniamted gifs dont render correctly and dont animate. The flash movie doesnt load and the javascript doesnt active. IN IE5+ and NS6.1 this page works correctly Reproducible: Always Steps to Reproduce: 1. View the url with NS6 or IE5+ 2. Then view it with this build or any of the recent nightlies. 3. Actual Results: As the description explains Expected Results: Rendered the page correctly and the DHTML should be working.

1) Mozilla does not come with flash 2) Animated gifs are a known problem being worked on. 3) Could you go into a bit more detail about what's wrong with the Jsvascript?

I have the flash plugin installed in mozilla and do not have a problem accesing other pages which have flash on them. I cannot be more specific with the javascript problems becuase the page just sits there and doesnt throw errors. Id very much like to be more specific about this, but really cant pnpoint a cuase of the problem. In NS6 and IE5+ the page runs just fine and is coded by W3C standards as much as possible. eg theres some corss-browser sniffing for browser width and height etc, but apart from those sorts of issues the page should theroetically render and display correctly.

1) The flash movie loads fine for me 2) Known issue 3) I get errors in the console : * else if (line1Lyr.left = (x_array[index]/x_array[x_array.length-1]*pageWidth)) { it should be "==" and not "=". * Line 164 : Can't convert timer2 to an integer The relevant code is probably this : timer2= setInterval("showIt()", delay1); * Error: uncaught exception: [Exception... "Parameter is not a number" code: "1005" nsresult: "0x805303ed (NS_ERROR_DOM_NOT_NUMBER_ERR)" location: "file:///C:/Documents%20and%20Settings/fabian/Mozilla/testcases/dhtmlnirvana1.htm Line: 164"] Apart from that, everything seems fine. Could you tell us what was working on NS6 and not in Mozilla? I don't have access to another browser than Moz right now. Thanks.

Ok I retried this and I can still load the flash plugin without a problem. The animated gifs are still broken, but that's known. As for the javascript, could you please tell us what exactly doesn't work? When mousing over "News", I get "Recoded to be w3c compliant" even though clicking on it does nothing so far (neither on IE nor on Mozilla). When mousing over "Jim Dandy", I get "IE-only". Please be more specific as to which part of the site doesn't work, thanks for helping us debugging it! (because obviously the author is making a lot of effort to support us)

Ok im the actual author of that page and yes I am attempting to support mozilla via both my web sites and through some upcoming articles at webreference.com So lets go through the bugs again. Ok on the aniamted gifs, glad you guys are on to it. After a bit more testing this is what I found to be happening with the flash movie loading. If I go directly to http://dhtmlnirvana.com/ then the flash movie loads fine, but if i go to http://dhtmlnirvana.com/oneproject/ first (the flash movie loads here and mozilla doesnt have a problem with this page) and then go to http://dhtmlnirvana.com/ then the flash movie doesnt load at all. Posibbly a cache issue of some form? On the js issue I get a stalled page at dhtmlnirvana.com. For example if you view it in IE5+ or NS6 the lines move, but in mozilla the lines stay static (thats the issue I am struggling with in that it works fine in NS6 but not on mozilla). In other words none of the animation routines trigger with recent mozilla builds. Does this help any? Would my system specs help any further? Let me know

On Linux: Going straight to http://dhtmlnirvana.com/ loads the flash for me, as does /oneproject/ - however going from /oneproject/ to / causes the background on / to continually flash in different colours and not load the flash presentation. On / I don't see any lines moving at all.

not mine, desale?

OK here's my opinion on this. We should split the flash bug into another one, that would go to Plugins. We'll concentrate in this bug on the DOM problems. Unfortunately I'll not be able to write any testcase for it anytime soon :( Could use some help. psych3@primus.com.au (for lack of a better name), could you please split up the flash bug? Thanks alot. For the DOM part of this bug: The way the DOM is handled has been vastly rewritten last week. Could you please re-test again? Using build 2001051308 the lines in the graphic in the middle of the page animate exactly as in IE5. Thanks again.

Yes I can split up the flash bug give me a few days as I have found quiet a number of other bugs in recent nightlies and .9 milestone. Im just waiting for a good windows build and then download and recheck everything in case its all well now. Anyway I will do the flash bug split. BTW my name is Eddie Traversa.

Marking NEW then.

OK let's carry on as Fabian suggests, making this a DOM bug by updating summary. You say it worked in Netscape 6... regression keyword, plus mozilla0.9.2 nomination. This needs further triage... Edie: can you examine Fabian's comments about the possible JavaScript error, and see if that fixes the issue, and report back ASAP, thanks.

Ok Ive rechecked the page with both NS6 and mozilla build 2001052104 In NS6 the lines animate identical to IE, with mozilla however they do not animate they are stuck. Ive checked the javascript console in both NS6 and mozilla for any potential scripting errors at my end and I get a clean bill of health here. On a brighter note, I am working of a cleaner js code base for another site and mozilla runs fine here except for some rendering problems on gifs in external html files http://dhtmlnirvana.com/jazz/ Ill check through the bug base and see if this has allready been filed if not ill post another bug. Eddie Traversa thats a considerable improvement over last months builds as this site crashed mozilla outright so I think you are headed in the right direction here.

There's just no way I can dig into this code any time soon, if someone creates a minimized testcase and tells me what the problem is I might get to this sooner.

But thats the problem, if you create standalone examples then the examples run fine. Its when you integrate everything into a complex DHTML page that mozilla falters. For example, a lot of the opacity stuff works (with a workaround) as standalone examples, but when you integrate it into a full dhtml page then mozilla / NS6 has some serious performance issues that make for an unpleasant experience for people browsing that page.

Is this purely a performance problem then?

it may well be, i just tried opening the JS debug console and when that opens the lines move a little, which suggests its something other than js issues does it not?

Is the updates on the page based on JS timers? If so, could you try increasing the delay's in the code to see if that makes things work better?

Ok ater some testing heres whats happening, I can slow down the timers but they have to be slowed considerably the lines will move in Mozilla. I can also unhook another animation sequence that is in an endless loop and that also sees the lines animating. The same animation techniques, ie, the path animations are used at http://dhtmlnirvana.com/oneproject/ where the circles animate based on a path animation. The differnce here is that everything at One Project is based on timers, and the delay between one animation starting and commencing is considerable compared to http://dhtmlnirvana.com/ The above suggests to me that it is not a DOM related or JS related issue but rather a performance issue.

Hyatt, this page might be interesting to quantify if you start looking at style code performance on DHTML pages.

Updating QA contact to Shivakiran Tummala.

Mozilla 0.9.1 doesn't show my page as intended either: http://clickworkers.arc.nasa.gov/training/crater-marking.html shows animations (starbursty points, red circles drawing themselves) in 0.7 (2001010816) but not 0.9.1 (2001060712). The animated GIF by itself works fine: http://clickworkers.arc.nasa.gov/graphics/new-circle.gif But when it's inline in a page, set by JavaScript, it's not animating. (This isn't an ideal test case, since by design the last frame of new-circle.gif looks just like the still image it replaces it with, old-circle.gif).

Re my last comment: I've decided that the bug I discovered is most likely separate from this one, so I've posted a new bug report, Bug #86572, with a test case attached.

Bugs targeted at mozilla1.0 without the mozilla1.0 keyword moved to mozilla1.0.1 (you can query for this string to delete spam or retrieve the list of bugs I've moved)

Marking as dup of bug 21762, as this bug doesn't demonstrate any specific problem. Please see my post in npm.dom for more information. *** This bug has been marked as a duplicate of 21762 ***
