I can see that the MemberDataTool is able to call the portal_membership tool using the getToolByName method. (and there are hundreds more examples where this is successful) But when I try to do it I get an attribute error, (before you ask, yes the first tool has been successfully created first prior to me trying to add this second tool.): Traceback (innermost last): Module ZPublisher.Publish, line 101, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Products.CMFCore.utils, line 427, in manage_addTool Module Products.ParasynPIP.ParasynChartTool, line 87, in __init__ Module Products.ParasynPIP.ParasynPIPChartTool, line 80, in getParasynPIPTool Module Products.CMFCore.utils, line 75, in getToolByName AttributeError: parasynpip_tool My code in the second tool looks like: def __init__(self): ppt = getToolByName(self,"parasynpip_tool") Any help anyone could provide would be fantastic, thanks in advance. My Install is zope 2.7.3, python 2.3, plone 2.0, no other installed products, on windoze, ____________________________________________ Peter Millar
