Re-order task error in firefox

Gantt
#1

Hi,

I encountered an error in firefox while reordering tasks.
Error in this part of code (codebase).
As i reorder task, i get this error : “TypeError: t is null”
But this is working in chrome.
Please advise.

Code Snippet :
gantt.locate = function(t) {
var e = gantt._get_target_node(t);
if (“gantt_task_cell” == e.className) return null;
for (var n = arguments[1] || this.config.task_attribute; e;) {
if (e.getAttribute) {
var i = e.getAttribute(n);
if (i) return i
}
e = e.parentNode
}
return null
}, gantt._get_target_node = function(t) {
var e;
return t.tagName ? e = t : (t = t || window.event, e = t.target || t.srcElement), e
},

Hi,
I’ve done a quick check on this sample and haven’t reproduce the issue. Can you give an instructions or required settings to reproduce the error?

Hi,

Is there an blockable event before saving the new order?
I will revert positions when conditions were not met.

Thanks,

Hi,
currently there is no blockable event. We’ll consider adding it in a future versions

Hi,

I made this work by using the movetask gantt function.
I saved the previous level and parent. If conditions were not met after drag end, I will revert the task to its original position.
