WebViewer javascript error

[John Swenson]

I got this Javascript error in my WebViewer (roughly translated in english):
"unable to get the value of 'rows' property: object not set to instance (null)"

Then Visual Studio 2010 stops in the following js function:

ReportViewer.prototype.get_Height = function ()
{
    var reportTable = document.getElementById(this.reportTableId);
    var lastRow = reportTable.rows[reportTable.rows.length - 1];
    var oldDisplay = lastRow.style.display;
    lastRow.style.display = "none";

    var viewer = document.getElementById(this.clientID);
    var clientHeight = viewer.clientHeight;
    lastRow.style.display = oldDisplay;
    return clientHeight;
}

the extact line that fires the error is:

var lastRow = reportTable.rows[reportTable.rows.length - 1];

I'm using Q2 2011 SP1.
Thank you.

Hi John,

Thank you for bringing this to our attention. However we have not been contacted with such a problem so far and we have not been able to reproduce it with the latest official Q2 2011 SP1 release on any of the latest browsers (IE 9, Firefox 7.0.1, Chrome 14.0.835.202 m and Opera 11.51). Can you please provide us with the exact browser and version (if not the latest please upgrade and try again).

If the problem persists/happens with the latest version of Telerik Reporting and the latest browser version, we would appreciate if you prepare a sample runnable project that exhibits the problem. Once we review it, we would be able to provide more information on the culprit.

Best wishes,
Steve

I get the error on IE9, FF 7.0.1 and Chrome 14.0.835.202 m Windows.
I forgot to tell that as a result of the error, the "Print" and "Refresh" seems to be disabled or anyway they do nothing and the "NavigateBack" button.... prints the report!
I'll see if I can make a project to reproduce the problem.

Regards.

I've just submitted a support ticket for this problem, togheter with a sample application to reproduce the problem
Actually, with the sample application you can reproduce two problems I'm having: this one and one other discussed here:

http://www.telerik.com/community/forums/aspnet-ajax/ajax/error-when-trying-to-update-ajaxified-textbox-through-a-button.aspx

The support ticket number is #473284
I'm sorry for having mixed the two problems but I'm in a hurry, really.

Best regards.
