[Zope] getView/getMultiAdapter and 'global name 'view' is not defined'

[Maciej Wisniowski]

Hello

I have a view defined for my content class that uses both view template 
and view class.
In zcml it looks like:

<browser:page
      for=".xyz.IXyz"
      class=".browser.xyz_view.XyzView"
      template="xyz_body.pt"
      name="render"
      permission="zope2.View"
  />

in 'xyz_body.pt' I have statements like:

------------------------------------------------------------------------
<div tal:define="xyz_dict python: view.xyz_function();">
------------------------------------------------------------------------

where 'xyz_function' is defined in 'XyzView' class.

Calling @@render from another view or directly by
URL in browser works, but when I'm using:
------------------------------------------------------------------------
rnd = zapi.getMultiAdapter((self.xyz_instance, self.REQUEST), Interface, 
name='render')
------------------------------------------------------------------------
or

------------------------------------------------------------------------
rnd = getView(self.xyz_instance, 'render', self.REQUEST)
------------------------------------------------------------------------

where 'xyz_instance' is a instance of content class (in ZODB)
that implements IXyz I get:

------------------------------------------------------------------------
NameError   
Exception Value    global name 'view' is not defined

------------------------------------------------------------------------

How can I call such view from python code?
I'm using Zope 2.9.1.
In Zope 2.8.5 it was possible to use
context.xyz_function() instead of view.xyz_function() but now it causes
errors.

One more question - is it necessary to inherit from
Products.Five.BrowserView in view class?
I think that I've found somwhere that ZCML itself puts BrowserView
into base clases of view class...?
