Yes.
 ------------------------------------------
 Step1 - Create Class
 ------------------------------------------
 Create Class with these values:
 >Web: Try7
>Class: Try7Faq 
 ------------------------------------------
 Step1b - Complete Edit Save of Class
 ------------------------------------------
 Add Title:
 >'Try7 Class Title' 
 Leave Default Parent - but Change defaultweb:
 >>#set($defaultparent = 'XWiki.${class}Class') 
This is the mistake, you didn't update the class name correclty. Should be:
#set($defaultparent = 'Try7.${class}Class')
The template assumes that classes are created in the XWiki space, a
practice that was recommended in the early years, but doesn't stand
anymore.
 
>#set($defaultweb = 'Try7') 
 ------------------------------------------
 Step2 - Edit Class Add Properties
 ------------------------------------------
 Added two TextArea properties: TestA and TestB - default options
 ------------------------------------------
 Step3 - Click Create Document Sheet
 ------------------------------------------
 Add Title:
 > Try7 Document Sheet Title 
 Change Velocity template text:
 >#set($class =
$doc.getObject('Try7.Try7Faq').xWikiClass) 
 ------------------------------------------
 Step4 - Click Create Document Template
 ------------------------------------------
 Add Title:
 >Try7 Document Template Title 
 Change Velocity template text:
 >#includeForm('Try7.Try7FaqClassSheet')
 ------------------------------------------
 Step5 - Click Create Document Template
 ------------------------------------------
 Click on ObjectsTab -- 'Add Object from this Class' dropdown:
 >Added Try7.Try7FaqClass to ObjectsTab of
Document Template. 
 **NOTE: The two textareas show up fine - OK...
 Save and Exit...
 ------------------------------------------
 TEST - Create Instance Of Object/Document
 ------------------------------------------
 Click on the create document button....
 > Only the document title shows --
properties/textareas that were 
 added do not show ? I'm not sure why....
 Attached is an error stack (maybe unrelated) that I'm getting but not
 consistently when going through the above steps....
 Thanks
