JavaScript-Error inTreeViewMenu

sorry, if this is the wrong place for this:

I'm using a TreeViewMenu in a Skin, like this:

<dnn:TREEVIEW runat="server" id="dnnTREEVIEWxxxxx" HeaderText="xxxxx" BodyCssClass="stpNormal" CssClass="TreeViewMenu" headerCssClass="TreeViewMenu_Header" headerTextCssClass="xxHead" NodeOverCssClass="TreeViewLinkOVer" NodeSelectedCssClass="TreeViewLink" NodeChildCssClass="TreeViewLink" NodeCssClass="TreeViewLink" nowrap="false" treeIndentWidth="8" />

this tree is shown properly and works fine. the only problem is that on every page a JavaScript-Error is shown in the status bar.

the error message is:

Error ``oCtl has no properties'' [xs] in file ``http://localhost/PortalName/js/dnn.controls.dnntree.js'', line 7, character 0.

The line contains the following:
dnn.controls.controls[oCtl.id] = new dnn.controls.DNNTree(oCtl);
and is part of the tree initialization:
dnn_control.prototype.initTree = function (oCtl)
{
   //oCtl.innerHTML = '';//temp
-->   dnn.controls.controls[oCtl.id] = new dnn.controls.DNNTree(oCtl);
   dnn.controls.controls[oCtl.id].generateTreeHTML();
   return dnn.controls.controls[oCtl.id];
}
the oCtl is NULL. Therefore the error when acessing it

Does anyone have an idea how to solve this? why oCtl is null? I'm using DNN 3.2.2

Thanks

Re: JavaScript-Error inTreeViewMenu

oCtl is the object reference to the control that represents the tree. If you look at your page source, you will see the call to initTree. The param passed to this ends up being oCtl.

What browser are you using? Any chance you can put the page in a public place and provide me with a url?

Re: JavaScript-Error inTreeViewMenu

Problem solved.
I have multiple trees in a navigation bar. some of the trees are only visible when some conditions are true. this was decided when the pre-render handler of the corresponding tree is called the tree set to (in)visible. This caused the Nul-error in the js init method of the tree.
I put the trees in one table and I'm now setting the cells of the table containing the trees to visible(invisible) instead of the tree self and this solved the problem.
