I have a web grid inside of a web pane. When a user clicks on a row a Web Dialog box is opened a more information is displayes regarding the item. The user can edit the information. When the Dialog box is closed, in the OnClosed event I call a client side refresh of the Web Grid. It processes for a second or two and then the whole browser is closed with an Unhandled Exception in iexplorer process.

/*
Returns the Site Grid object
*/
function GetGrid(gridName)
{
    var grid = ISGetObject(gridName);
    return (grid);
}

/*
Refreshes the grid data and UI
*/
function RefreshGrid(grid)
{
    grid.ClearSelectedObject();
    grid.RootTable.UpdateUI();
    grid.RefreshAll();
}

/*
Load the request editor dialog
*/
function LoadWorkScheduleEditorControl(editType, taskID, jobType)
{
    if (_jobDialog == null)
    {
        _jobDialog = ISGetObject("DialogTaskEditor");
    }

    var contentUrl = "Windows/Dialogs/" + jobType + "/WorkSchedule.aspx?method=" + editType + "&task=" + taskID;
    _jobDialog.ReuseIFrame = true;
    _jobDialog.SetContentURL(contentUrl);
    _jobDialog.ClientSideEvents.OnClosed = TaskEditor_OnClosed;
    _jobDialog.ShowDialog();
}

/*
Event handler for closing request editor dialog
*/
function TaskEditor_OnClosed(id, dialogResult) 
{
    try 
    {
        _jobDialog.SetContentURL(_inactiveDialogURL);
//this is where it fails and closes the browser
        RefreshGrid(GetGrid("WebGridTaskList"));
    }
    catch (e) 
    {
        alert(e.Message);
    }
}
 
Any ideas?
