Hi everyone

I m trying to hide plone 4.3 default logo from the file system using viewlets. Here is my code which inherits the default code of viewlets from eggs directory. (i.e /eggs/plone.app.layou t-2.3.4-py2.7.egg/plone/app/layout/viewlets/common.py ->class LogoViewlet(Vie wletBase)

[B]common.py[/B]

        portal = self.portal_state.portal()
        bprops = portal.restrictedTraverse('base_properties', None)
        if bprops is not None:
            logoName = bprops.logoName
        else:
            logoName = 'logo.jpg'

        logoTitle = self.portal_state.portal_title()
        self.logo_tag = portal.restrictedTraverse(logoName).tag(title=logoTitle, alt=logoTitle)
        self.navigation_root_title = self.portal_state.navigation_root_title()

[B]createPictMenu.py:[/B]
(i m pasting here only the class which is for inherting the default viewlets code from the eggs directory.)

class LogoViewlet(ViewletBase, bdrMenuView):         
    def __init__(self, context, request, view, manager):
         super(LogoViewlet, self).__init__(context, request, view, manager )
         self.__parent__ = view
         self.context = context
         self.request = request
         self.view = view
         self.manager = manager
    
    def index(self):  
        print "**************Hai I am from viewlet class method*************"
        return self.createPictMenu()

while running i m getting this error:

You haven't told us which line of code is throwing the error but the message itself is fairly clear. It's saying you called a function that requires 5 values but you only gave it 3.
