Hi, I'm just writing my first Zope (2.4.0) Produkt in Python, but I have some problems : I have two classes, one of them is folder-like and should contain the other. I followed the advice in the 'Zope Developer Guide' and created all neccessary files (interfaces, implementations, __init__.py,...) and I could use the objects in Zope. Everything fine so far. But now I want to call a memberfunction of an instance through the web. For example: I have an instance of an object with the id 'MyInstanceA' in the folder 'TestFolder'. Now I want to handle the data posted from a form via a memberfunction of this instance. The function is defined as: def handleFormData(self,param1,param2): ... If I try to access this function through the url '.../TestFolder/MyInstanceA/handleFormData' I get a 'resource not found' error. BTW the function is declared as public. If I name the function 'index_html' I also get an 'resource not found' error, but if I remove index_html Zope finds again the index_html on a upper level in the hierachy. I think I understand something wrong, so could somebody give me a hint ? greetings Achim
