Error: 'Object reference not set to an instance of an object' in HTML export using Visio 2010

Ref: JB201104121316 
Last Edited: 22nd August, 2011
Development Ref: 84 
Fixed in PN 11.1
An error is reported when exporting to HTML using Visio 2010.
08/04/2011 09:01:35
"C:\Users\PN User\Documents\Process Navigator\Intranet\pn - map 10.map page-1_files\data.xml" could not be amended.
Hyperlinks in the associated HTML files may not work correctly.
Object reference not set to an instance of an object.
The cause is still under investigation, but is thought to be related to content in the HTML export of Visio 2003 and Visio 2007 that isn't in that of Visio 2010. Process Navigator amends the hyperlink information in the data.xml file, but the line of the following type isn't in the Visio 2010 export.
<HLURL:AbsoluteURL>file://C:/Users/PN User/My Documents/Process Navigator/Intranet/Drill-down Test/pn - map 10a.activity 1.html</HLURL:AbsoluteURL> 
Upgrade to Process Navigator 11.1, to be released on September the 1st.
Applies to:
  • Process Navigator
  • Visio 2010
