1. $obj.accessCounter is not the property value, but is a shorthand for
$doc.display().
2. In order to make the changes persistent, you must also save the document.
#set($obj = $doc.getObject("Space.MyClass"))
#set($v = $obj.getProperty("accessCounter").value)
## if this is not a number property, you must also parse it
## #set($v = $util.parseInt($v))
#set($v = $v + 1)
$obj.set("accessCounter", $v)
$doc.save()
