Hi Frank,
is your InitIndicator-instance implementing the
IInitIndicatorFB-interface. This is absolutely necessary
for providing it as an utility. There's an easy test for this:
>>> from zope.interface.verify import verifyObject
>>> ii = InitIndicator()
>>> verifyObject(IInitIndicatorFB, ii)
True
I usually put this in the docstring of classes I want to use as
utilities. Just to make sure :-).

Hi,
is there any reason why a registered utility which is persistently stored
inside the site
manager is never found via zapi.getUtility(IMyInterface) ?
More information:
I wrote a package ( fb ) containing some components making the developer's life
easier. The package
provides a class fb.init.indicator.InitIndicator. A application depending on
the fb package is
supposed to make an instance of the InitIndicator, put it into the site manager
and register it.
As soon as the InitIndicator exists, the annoying "This site is not
initialized, yet"-message provided by the fb package's skin (which just
checks if "zapi.getUtility(IInitIndicator) is not None") disappears.
But: It *doesn't work* and a don't have the slightest clue why. This is,
what my application's initialisation routine does:
def initApplication(root):
sm=getSiteManager()
df=sm['default']
initindicator=InitIndicator('mpgsite','http://zope3.mpg.de/topic/MpgSite',u"no
info")
df['initindicator']=initindicator
sm.registerUtility(df['initindicator'],IInitIndicator,'','')
[...]
test=zapi.getUtility(IInitIndicator) # Works!
[...]
Querying the IInitIndicator component works directly after the registration
but *nowhere* else in my application.
Have you 'browsed' the utility via the ZMI 'Manage Site'?
Is there an instance there (in the site you expect it to be)?
If so the 'Registration' page could provide some useful info.
Yes. The instance is there, the registration tab shows the registration as
expected,
the site root folder itself lists the registration in site.registrations lists
the
registration as expected.
Registering via browser doesn't work either :-( .
BTW: I've got dozens of other utilities registered that are working perfectly.
Frank
