Hi,
I want to define a tree where branches_expr is not equal to "objectValues('Folder')". In fact a folder should appear in the tree just if one of its attributes is equal to a certain value. How can it be done? Install the Navigation Product, and use: branches_expr="navigate_filter(name,value,type,acquire,negate)"
name is the name of the attribute to be checked, must be given. value is the expected value of the attribute. Default: None, if None is given, any value matches. type is the type of the wanted objects. Default: 'Folder'. If None, any type does match. acquire Default: 0. If given a true (nonzero) argument, than the attribute will be acquired (inherited from the Folders above). In the default case, only attributes set in the object will count. negate Default: 0. If true, this will return the objects that did not match the above criteria. Typical example for a tree branches_expr: navigate_filter('donav','yes','Folder') or navigate_filter('donav',_.None,_.None) <-- this will match any object with a donav property, for example also Confera Topics, etc. Typical example for use as a Folder lister: <UL> <dtml-in "navigate_filter('dolistas',_.None,_.None)"> <LI> <A HREF="<dtml-var id>"><dtml-var dolistas></A></LI> </dtml-in> </UL> Andreas -- Andreas Kostyrka | andreas@mtg.co.at phone: +54/1/7070750 | phone: +43/676/4091256 MTG Handelsges.m.b.H. | fax: +43/1/7065299 Raiffeisenstr. 16/9 | 2320 Zwoelfaxing AUSTRIA
