[Zope] Probably simple problem...

[Thierry FLORAC]

Hi...

Well, effectively, that will probably work fine.
But my problem is that I may have several folders like "/dsi" (or even
subfolders of /dsi), each of them requiring use of the /news folder methods
(/news is a folder handling every methods relatives to news, and so each
folder can use these methods to display and handle several news relatives
to each subject).
So, I ABSOLUTELY don't want to duplicate my news handling methods in every
folder that have to display news...!!

Any idea ?? Is there any way to say in the /news/content_html method : I
want to call the "get_last_news" object which is in "my" folder, and not
anywhere else, without worrying of the place from which this method was
called ??
