Hi !

Thanks for answering.


I'm using Chrome, but i'm trying with Firefox with the same results.

I could detect the issue, and I solve it by commenting this string -->,t.datakey).related || <-- in the file FusionCharts.HC.js.


However, I would like to solve the issue by understanding what's wrong. And i've seen that the problem is in the event teardown. So , when i try to change the screen, this events tryies to clean or something, and then is when i get the error.



I can't give the Url becouse its a confidential site, but i'm working hard to reproduce de issue and send it to you. If I find the problem i'll post it. I'm thinking in some incompatibility between the jquery that my app loads and what FS load.


Well that's all the info i get till now.

I'm sorry for the multiple posts.


Thanks for you time :D

You'r wellcome rolleyes.gif


I've been working to get a reduced example wich I attach.


To force the error you have to :


Step 1 : load the index.php in Firefox with firebug 1.7 or higher

Step 2 : push the button to load the chart with the firebug console opened

Step 3 : pres f5 to reload the page

Step 4 : Detect the following error, t.datakey) is undefined


Line 78


The problem is the jquery Version that I'm using Version 1.3. The problem is that we are not able to change te version becouse it means spending a lot of time migrating.

In case you cannot repare the bug ( in case its a bug ) i would need to know if the the soulution I've posted before ( coment a part of code in FusionCharts.HC.js ) has any repercusion, becouse i'm afraid that if FusionCharts trigger's an event when the user is leaving the page is becouse its needed for something. So i would need to know what can happen if I coment that line.


Thank you very much, I hope the report its clear enough.
