Cannot set property 'top' of undefined jqxscrollbar.js:852

Hi,

We have a grid and it is sometimes throwing the following error:

Uncaught TypeError: Cannot set property ‘top’ of undefined jqxscrollbar.js:852
$.extend._setElementTopPosition jqxscrollbar.js:852
$.extend._positionelements jqxscrollbar.js:1179
$.extend.setPosition jqxscrollbar.js:1084
$.extend._addHandlers.addHandler.self.buttonDownCapture jqxscrollbar.js:439
jQuery.event.dispatch jquery.js:4692
jQuery.event.add.elemData.handle jquery.js:4376

This line of code is: element[0].style.top = y + ‘px’;

We are using an embedded version of Chrome. This only happens on two machines so far and is inconsistent. Both machines are XP (we have a mix of XP and Win7).

This doesn’t make sense to me at all. It appears as if the ‘style’ property of the underlying DOM element is not set. What makes it more weird is that this element is accessed further down the stacktrace successfully (in _positionelements method).

Is this an issue that anyone has come across before? Any idea how I can get around it?

Thanks,
Niall.

Hi Niall,

We have never encountered such issue. Please, provide an example which demonstrates it and make sure that you use jQWidgets 3.2.2 and jQuery 1.7+

Hi,

We are using jQWidgets 3.2.2 and JQuery 2.0.2, so that’s not an issue.

Unfortunately it only happens inside our embedded Chromium container, it doesn’t happen when using Chrome directly, so I can’t forward you a sample that recreates the issue.

Thanks,

Hi crosbyn,

Unfortunately, since we cannot reproduce it, we would not be able to help without a sample which demonstrates the reported behavior.
