  • Use undocumented site.ini setting to make it work like it used to

    I just spent three hours trying to figure out why this function no longer allows you to upload new objects and edit existing ones after upgrading a large site for a client... Turns out it was changed on purpose and that there's an undocumented site.ini setting to make it work like it used to:

    [BackwardCompatibilitySettings]
    AdvancedObjectRelationList=enabled
  • INI-based limitations for browse selection method

    If you choose the selection method "browse", you can configure which browse type has to be used with an undocumented setting in content.ini:
    [ObjectRelationDataTypeSettings]
    ClassAttributeStartNode[]
    ClassAttributeStartNode[]=240;AddRelatedImageToDataType
    


    Where 240 is the class attribute id and AddRelatedImageToDataType is the browse type (this type can be configured in browse.ini).

    If for a specific class attribute no browse type has been specified, AddRelatedObjectListToDataType is used.

    The Object Relation datatype uses the same settings, but the default browse type is AddRelatedObjectToDataType.
  • minor typo

    The last paragraph should read:

    ...or an array of ezcontentobject objects.

    (The link target is correct.)
