The snippet looks cool but it's quite hard to understand what it does.
I've documented:
http://code.xwiki.org/xwiki/bin/view/Snippets/GenericXMLApiSnippet
Here is the corrupted class:
http://patternlanguagenetwork.myxwiki.org/xwiki/bin/view/Cases/CaseClass
I've never seen that :) Something is indeed deeply broken since the
rendering is failing to display but I don't know why.
This is very bad for me, because I can't access that class in any way. All I
need is to rename ".unused" back to "unused", or roll back one
version, but
anyway I try to reach that, I get the same error. I think is might require
low-level access to fix.
The problem started when I renamed a property to ".unused". I thought I
could then add something like:
#if (!"$propertyName.startsWith("."))
to hide unused properties.
I think what happened is this:
The class definition is stored (or processed) in XML, and having a property
name starting with '.' confuses the parser.
For example,
http://patternlanguagenetwork.myxwiki.org/xwiki/bin/view/api/genericXML?xpa…
provokes this:
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
reading document Cases.Woodforthetrees
Wrapped Exception: Error number 3202 in 3: Exception while reading document
Cases.CaseClass
Wrapped Exception: Error number 2002 in 2: Error parsing xml
