Export to PDF Tool - Empty Map

[ShaningYu]

I used David Springs' tool: Export PDF web application and GP service sample from
http://www.arcgis.com/home/item.html?id=8f16fdeef39c46b3952002b2d85ea5de.  I loaded the widget in my project and then re-compiled the code.   However, after I 'Generate PDF', I clicked 'Download Map' button, the PDF page: http://stlouis.esri.com/arcgisjobs/exportpdf/exportpdf_gpserver/j02b1cf79bae54815bc3591d57862d4a8/sc... pops out. However, it is an empty map but only with Miles ruler. I guess this might be due to the API version difference.  Has anyone used this component and is willing to provide his/her advise to debug this problem? Thanks.

Found that it is related to multiple issues.  One is the version related.  For ArcGIS 10.1, publishing a geoprocessing toolbox is different from the previous version.
