-.. XXX userCallback / user_callback
+python/ajax dynamic callbacks
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+CubicWeb provides a way to dynamically register a function and make it
+callable from the javascript side. The typical use case for this is a
+situation where you have everything at hand to implement an action
+(whether it be performing a RQL query or executing a few python
+statements) that you'd like to defer to a user click in the web
+interface.  In other words, generate an HTML ``<a href=...`` link that
+would execute your few lines of code.
+
+The trick is to create a python function and store this function in
+the user's session data. You will then be able to access it later.
+While this might sound hard to implement, it's actually quite easy
+thanks to the ``_cw.user_callback()``. This method takes a function,
+registers it and returns a javascript instruction suitable for
+``href`` or ``onclick`` usage. The call is then performed
+asynchronously.
+
+Here's a simplified example taken from the vcreview_ cube that will
+generate a link to change an entity state directly without the
+standard intermediate *comment / validate* step:
+
+.. sourcecode:: python
+
+    def entity_call(self, entity):
+        # [...]
+        def change_state(req, eid):
+            entity = req.entity_from_eid(eid)
+            entity.cw_adapt_to('IWorkflowable').fire_transition('done')
+        url = self._cw.user_callback(change_state, (entity.eid,))
+        self.w(tags.input(type='button', onclick=url, value=self._cw._('mark as done')))
+
+
+The ``change_state`` callback function is registered with
+``self._cw.user_callback()`` which returns the ``url`` value directly
+used for the ``onclick`` attribute of the button. On the javascript
+side, the ``userCallback()`` function is used but you most probably
+won't have to bother with it.
+
+Of course, when dealing with session data, the question of session
+cleaning pops up immediately. If you use ``user_callback()``, the
+registered function will be deleted automatically at some point
+as any other session data. If you want your function to be deleted once
+the web page is unloaded or when the user has clicked once on your link, then
+``_cw.register_onetime_callback()`` is what you need. It behaves as
+``_cw.user_callback()`` but stores the function in page data instead
+of global session data.
+
+
+.. Warning::
+
+  Be careful when registering functions with closures, keep in mind that
+  enclosed data will be kept in memory until the session gets cleared. Also,
+  if you keep entities or any object referecing the current ``req`` object, you
+  might have problems reusing them later because the underlying session
+  might have been closed at the time the callback gets executed.
