 Hi all,
 I have a problem with a class sheet.  I have been working on a project for
 the past few weeks.  The class sheet has been edited many times.  But
 after doing the last edit the following happens.
 
 1.
 I can not access the class via the class editor page where all classes are
 listed, so i cant see the class sheet or the class properties page.  The
 same error is displayed when accessing any document created using this
 class.  I get this error:
 
 Detailed information:
 
 Error number 3202 in 3: Exception while reading document
 XWiki.ExpenseClass
 Wrapped Exception: Error number 2002 in 2: Error parsing xml

 SuppBusiConfTotal

 0
 SuppBusiConfTotal
 30
 
 etc... for every property in the class (150 or so).
 
 I can access the class sheet by using its URL.  Editing or changing the
 class sheet makes no difference.
 I cannot access the class property page using its URL.
 
 2.
 The bread crumb link where parent and space is displayed for documents
 created using this class shows this:
 Scheduler: ${pdoc.displayTitle}  $tdoc.displayTitle  
 
 3.
 I can not see the Expense.webhome page.
 In this page I use seachDocuments to find all documents associated with
 XWiki.ExpenseClass.
 It looks like a class property has been corrupted and any attempt to read
 any document associated with the class fails.  
 
 Error number 4001 in 4: Error while parsing velocity page Expenses.WebHome

 4.
 To get around this problem I created another class, matching the
 properties of the first class.  That worked fine for a little while, even
 after editing the class sheet many times.  This second class is now doing
 the same thing as the first class.
 Just to let you know; in the class sheet i am using searchDocuments to
 find documents created using other classes.
 
 So what am i doing wrong?   Is there any way i can fix this?
 
 
 
 

With help from Ludovic Dubost i managed to fix the class.
The XWD_CLASS_XML field in the class document has a limit of 65Kb.
Looking at the XWD_CLASS_XML field for XWiki.ExpenseClass showed a size of
65353 bytes.
Any text over 65Kb didnt seem to save properly.  The xml close class tag was
missing which caused my problems.

It would be nice if xwiki warned the user that they have exceeded the
maximum size of the XWD_CLASS_XML field.  
I noticed alot of space was used up when databaseList was used.  The query
is saved with the property.

I have tried to delete the class through code.

#set($thisDocum=$xwiki.getDocument(XWiki.ExpenseClass))
#if($thisDocum != )
 $thisDocum.fullName
 $thisDocum.delete()
#else
 could not find document
#end

The following error was shown:
org.apache.velocity.exception.MethodInvocationException: Invocation of
method 'getDocument' in  class com.xpn.xwiki.api.XWiki threw exception
com.xpn.xwiki.XWikiException: Error number 3202 in 3: Exception while

Wrapped Exception: Error number 3202 in 3: Exception while reading document
XWiki.ExpenseClass
Wrapped Exception: Error number 2002 in 2: Error parsing xml ?xml
version=1.0 encoding=UTF-8?

Does anybody know what can be done to delete this class?  Any help would be
great.
