#2

You have an error in this xml –

Predecessor task (694000000412019) position error. Reduce duration of predecessor task (694000000412019) or increase EST of child task (694000000412043)

You should fix it before you load. It says that a child task starts before the parent.

#3

you are getting that error because your this.hoursInDay must have been set to 8.
My this.hoursInDay = 24. Please load my xml with this.hoursInDay = 24 , you will definitely get the "Unresponsive script " message (please note that a part of the chart is loaded before I get this message). I repeat that chart for the xml I gave you is loading fine in Google Chrome , but I get the issue in MOZILLA and INTERNET EXPLORER ( this shows that there is no error in my xml). I have been evaluating dhtmlxGantt and Im interested in purchasing it in the immediate future , but this issue is proving to be a big hindrance. So please look into this issue and get back to me as soon as possible.

This is the exact error message Im getting:-

A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.
Script: file:///home/badrinathr/dhtmlxGantt/codebase/dhtmlxgantt.js:3961

#4

Agree, FF is really slow. It does load your XML on my PC, but it takes around 4 sec. Chrome is instant in this case. I will try to workaround this and let you know.

#5

Yes, it seems Firefox is really slow on rendering your nodes. IE9 and Chrome are really fast.
I have tried to remove parent DIV from DOM during rendering and then add it back after all, but it does not help - Firefox is still slow to render them. No solution for Firefox yet. it’s not slow JavaScript, it’s slow rendering mechanism.

#6

Thanks for the prompt reply. Many of my clients use FIREFOX and it is absolutely essential for me to get this problem fixed. dhtmlxGantt is a really superb product and Im ready to purchase the Commercial license immediately after you get this fixed. So please give me a time frame of when you can get this fixed.

#7

That is a Firefox browser issue to slowly render HTML content. We will try to find some workaround, but for the moment it seems impossible.

#8

I got your point and it would be great if you find me a work around. But for the time being i want to know if removing any part of your code which constructs HTML content in a for loop render the chart faster in MOZILLA. For example :-

  1. I can do without the div with className = “taskPanel” (i mean the background grid of the chart). I see that the height and width of the grid is increased in a for loop. Will removing this DIV help?
    2 . I do not use the tag (i use only the tag). So will removing code related to child tasks help?
    or Can you suggest any other part of the HTML , which when removed will render the chart perfectly in FIREFOX.
#9

Please give it a try, (but I do not think it would significantly improve FF rendering.)
Currently we have other tasks in development.
