Hi Massimo, thanks for your sharing another undocumented magic of
web2py, the response.headers['web2py-component-flash'], in this post,
http://groups.google.com/group/web2py/msg/6049af89fbfa2bfc
That makes me think that is just another example to justify my
proposal, this time it is refined to automatically convert
reponse.flash into response.headers['web2py-component-flash'] when
needed.
Check this out. It is self-documented.
{{ '''
With this generic.load file, you can use same action to serve two
purposes.
Example modified from http://www.web2py.com/AlterEgo/default/show/252:
def index():
return {
'part1':'hello world',
'part2': LOAD(
url=URL(r=request,f='auxiliary.load'), # Notice the
".load" extention
ajax=True),
}
def auxiliary():
form=SQLFORM.factory(Field('name'))
if form.accepts(request.vars):
response.flash = 'ok' # No need for this anymore:
response.headers['web2py-component-flash'] = 'ok'
return {'': "Hello %s" % form.vars.name}
return {'':form} # No need for "return form" anymore!
>From now on, single auxiliary() can serve two purposes:
http://.../auxiliary.load serves as a raw component LOADed by other
action
http://.../auxiliary serves as a normal html page as usual
# PS: Please keep all above explanation for people to know when and
how to use it.

{{ # Does NOT extend layout.html, purposely.}}
{{response.headers['Content-Type']='text/html'}}
{{if response.flash: response.headers['web2py-component-flash'] =
response.flash}}
{{if len(response._vars)==1 and not response._vars.keys()[0]:}}
{{=BEAUTIFY(response._vars.values()[0])}} {{ # To bypass the silly
colon }}
{{else:}}
{{=BEAUTIFY(response._vars)}}
{{pass}}
