Hi Zopistas I experience Problems using ZCatalog, See following example: <dtml-in "Catalog(meta_type='ZClass_seite_press',region=zregion)"> where zregion is one string and region is a list indexd as text when i change this to <dtml-in "Catalog(meta_type='ZClass_seite_press',region in zregion)"> where zregion itself is a list, containing 3 or more strings that should match on some instances of ZClass_seite_presse i can't even get this into zope, because i recive this error non-keyword arg after keyword arg , for tag <dtml-in "Catalog(meta_type='ZClass_seite_presse',region in zregion)"> so, how would i get the goal, searching in ZCatalog with my list as mentioned in the Howtos. Thanks in advance to anybody out there. -- ingo wilmer geschäftsführung tel +49 251 98704-22 | jüdefelder str. 37 | http://www.zeitspringer.de fax +49 251 98704-11 | 48143 münster |
