Hello, on an own product I've coded this: index_html = Globals.DTMLFile('dtml/viewLinkListItem', globals()) __str__ = index_html If I start now Zope again a message PROBLEM(100) Init Ambiguous name for method of Products.KBProducts.kbarticle_impl.LinkListItem: "__str__" != "index_html" appears. Anything behave as it should, so the string representation of this product works if i For instance call it up within a dtml-loop: <dtml-in getLinks()> <dtml-var sequence-item> </dtml-in> In this loop the LinkListItem Product is rendered as defined in index_html Does anxboy has any ideas about the Zope message ?? Thanks in advance Thomas Adams
