Hello, * I have 2 Folders (Yihaw ZClass instances) * both folders have News objects (cataloged) I put the news on the front page via (this is taken from Yihaw, simplified for the demonstation, but still have the problem) this code <dtml-in "Catalog( meta_type='Yihaw News Item', sort_on='bobobase_modification_time', sort_order='reverse')" size=30 start=query_start> <dtml-with "Catalog.getobject(data_record_id_)"> <dtml-var absolute_url html_quote> - <dtml-var title_or_id html_quote><br> </dtml-with> </dtml-in> Problem is that some news items are OK and some raise an exeption on <dtml-var title_or_id> told to be missing (!!??) It puzzle me because all news items are same ZClass instance and can be accesed normally via the zope interface, or directly, works well on view etc ... An other strange thing is when i supress the <html_quote> option, an authentication windows show up and gives an other traceback (see below). So when i put the <missing> option, to the <dtml-var title_or_id> it works well except nothing shows on the <dtml-var title_or_id>, and the right <absolute_url> is correctly shown for ALL the news item (including the b"bad" ones. In the context of both Yihaw Folder i have access content, view authorisation and view (via a local role). Only difference is : * in the folder with problem access content, view authorisation, view are given by hand at this level (without permission acquisition for those 3 for anonymous restriction) * in the folder without problem it's acquired from above (no anonymoiyus restriction) It happens even when i'm "manager". So i suspect some strange security problem, or more sure something i didn't understood on the acquisition/security machinery. And I'm not sure if it has relation with the fact those items are custom ZClass instances I hope this was clear and not too cryptic. The 2 traceback : 1- WITHOUT html_quote Unauthorized You are not authorized to access title_or_id.
