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()

I am trying to do exactly that, with a very silly code, and it doesn't work,
the value of the property doesn't change. Take a look at the code:
#set($obj = $doc.getObject("Space.MyClass"))
#set($obj.accessCounter = $obj.accessCounter + 1)
~~Number of accesses: $obj.accessCounter~~
The value displyed remains the one I defined by editing the object with the
object editor, what suggests the second set is not doing what I expected.
Do you have any idea of what am I doing wrong? Having retrieved an object on a page, how can I
update some fields of
that
object and save?
Doc.save() saves the document changing its version.... but, doesn't
update
the object-parameters. What am I missing?
You can use $doc.getObject(classname) to retrieve an object and
manipulate it's properties.
