This is an example of what can be the method : _______________________________________________ <dtml-var standard_html_header> <dtml-call "REQUEST.set('numero_doc' , '7')"> <dtml-in "Catalog({'numero_doc': _.str(numero_doc)})"> <dtml-with getObject> <dtml-call "Control_Panel.Products.PDFclass.propertysheets.PDFinfo.manage_changeProperties({'auteur': 'nicolas'})"> </dtml-with> </dtml-in> _______________________________________________ and I get the following error : Error Type: AttributeError Error Value: PDFinfo <!-- Traceback (innermost last): File /usr/local/Zope-2.3.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/local/Zope-2.3.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/Zope-2.3.1-linux2-x86/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/Zope-2.3.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/Zope-2.3.1-linux2-x86/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: test) File /usr/local/Zope-2.3.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: test) File /usr/local/Zope-2.3.1-linux2-x86/lib/python/OFS/DTMLMethod.py, line 189, in __call__ (Object: test) File /usr/local/Zope-2.3.1-linux2-x86/lib/python/DocumentTemplate/DT_String.py, line 538, in __call__ (Object: test) File /usr/local/Zope-2.3.1-linux2-x86/lib/python/DocumentTemplate/DT_In.py, line 713, in renderwob (Object: Catalog({'numero_doc': _.str(numero_doc)})) File /usr/local/Zope-2.3.1-linux2-x86/lib/python/DocumentTemplate/DT_With.py, line 146, in render (Object: getObject) File /usr/local/Zope-2.3.1-linux2-x86/lib/python/DocumentTemplate/DT_Util.py, line 334, in eval (Object: Control_Panel.Products.PDFclass.propertysheets.PDFinfo.manage_changeProperties({'auteur': 'nicolas'})) (Info: Control_Panel) File <string>, line 0, in ?
