There may be a problem with the encoding of the single quotes in the connectionName and startFolderPath parameters of the task flow binding. I had the same problem when I copied and pasted the values from the pdf version of the tutorial.
Try this:
Select the "Bindings" tab of "MyPage.jspx".
Double click on "taskFlow - doclibdocumentLibrary1"
Replace the single quotes in the values by re-typing them.
The tutorial uses these values:
${’MyTutorialContent’}
${'/Manuals'}
