Hi Telerik.
I have a strange error while working on a page which has a few telerik components including a splitter.
Sometimes it happens that I get an error
Microsoft JScript runtime error: 'this.get_splitter()' is null or not an object
and while debugging, Visual Studio breaks on the following code (in bold)
Telerik.Web.UI.SplitterPaneBase.callBaseMethod(this,"initialize");
if(this.get_splitter().isVertical()){
this.getVarSize=this.get_width;
this.setVarSize=this.set_width;
Unfortunately this problem happens rarely and without any particular sequence, hence difficult to reproduce :(
Can someone please guide me on the different possible causes?
Thanks

We get the same error on slower clients. We are not able to reproduce the error on our development environment.

Hi guys,
We have been contacted with this problem in the following thread:
http://www.telerik.com/community/forums/aspnet/splitter/splitter-behavior-differ-for-ie6-vs-ie7.aspx
However, this is a very specific case, the issue is reproduced only in specific technical configuration on the machine and with the treeview of Component One when there are many nodes and I am not sure that this is also your case. However, we never got a reproduction demo on which to investigate the problem (it seems that for some reason the RadPane's client object is created before the RadSplitter's one but the source code avoids this and we cannot find in what case this happens) and we never encountered it on our side.
This being said, we want to kindly ask you to provide a sample, fully runnable reproduction demo or at least a live url where we can observe the issue. Even if the problem occurs randomly, we will research further and do our best to solve it but in order to be able to do this we should have the reproduction setup and detailed reproduction steps.
Greetings,

We are able to reproduce this error on our website on a laptop. The error does not occur every time, but very frequently, i.e., over 50% of the time. Using the development tools shipped with IE8, I have found out, that method set_splitter is called too early.
Javascript stack trace when method set_splitter is called too early:
Javascript stack trace when method set_splitter is called correctly:
Somehow the Sys$Component$_setReferences is already called during $create of the first radpane. This seems to be too early. I hope this information helps you in finding a solution, because this bug makes our websites unworkable.

Hello Henk,
One of our customers has sent us a working project with which we can reproduce the problem locally (indeed it does not happen every time, but it is enough for us to start work on it) and we will do our best to fix it for the next update of the suite.
Best wishes,

Q3 2009 Release Code does not resolve the problem. For me, no splitter object used on the webform but the clientside code is reaised to deal with such an object!

Hi Paul,
The Q3 2009 version of the suite fixed the problem that is discussed in this thread.
I noticed that you have opened a support ticket with the same question and the simplicity of the code you have provided in it, leads me to believe that the problem you have is different from the one that is described in this thread. I already answered your support ticket and as I will need a running project in order to help you, let us continue this discussion in the support ticket.
Sincerely yours,
Tsvetie

We are no longer eligible to download newer versions of the controls, the latest we can get is the Q3 2009 beta(2009.3.1016.35). According to the release notes, this issue was fixed in Q3 2009(2009.3.1103). Is it possible to get a hotfix for this or do we have to pay for the full version in order to get it? We have one customer with many users that access our site using Sprint PCS cards and they are getting this error quite frequently due to having a slower connection.
