Hello all, I have a following interface definitions class IMyListObject(Interface): name = TextLine( title=u'Name') class IMyObject(Interface): name = TextLine( title=u'Name') ... my_list = List( title=u'My Object list', value_type=Object( title='My List Object', schema=IMyListObject) ) For adding the 'IMyListObject' into the my_list of 'IMyObject' I created a browser page for 'IMyObject' with zope.formlib AddForm's form_fields set to 'IMyListObject' and appended them to the 'my_list' field. That part works great. But I like to know, what is the preferred way of making objects inside the 'my_list' to be locatable. So that I can have an edit page or a display page for the 'IMyListObject' in that list. One approach what I thought was to make 'IMyObject' as a container with all other schema fields in place except the 'my_list' field and add the 'IMyListObject' to the 'IMyObject' as child objects, so that all the 'IMyListObject' objects are locatable. But I really wanted to know if it is possible to make objects inside a list locatable as that would be necessary in the case of creating an object tree of the following format. class INode(Interface): parent = Object( title=u"Parent node", schema=Interface ) children = List( title=u'Child nodes', value_type=Object(schema=Interface) ) INode['parent'].schema = INode INode['children'].value_type.schema = INode Please guide me in this regard. [Sorry for always cross posting to both bluebream and zope-dev mailing lists. Also I find another not so active zope3-users mailing list available. As most of my queries gets answered from zope-dev mailing list I am still in confusion on which mailing list to single out. Kindly bear with me.] Regards -- Joshua Immanuel HiPro IT Solutions Private Limited http://hipro.co.in
