Open the tool pane link from web part in MOSS 2010

In our project our web parts which were not configured yet render simple description and link to open web part properties in following format:

string.Format(@"<a href=\"#\" onclick=\"javascript:MSOTlPn_ShowToolPane2('Edit','{0}');\">open the tool pane</a>", webPart.ID)

It worked fine for MOSS 2007 but in MOSS 2010 when page is not in edit mode such link threw a javascript error.

Thanks to http://kvdlinden.blogspot.com/2010/04/open-tool-pane-javascript-error-in.html issue has been fixed. All you need is to add following control to the master page:

<SharePoint:ScriptLink language="javascript" name="ie55up.js" OnDemand="false" runat="server" />
