    Hi eZ Pub guys,

    In the manual for {def} it is stated that def does not support the 'name' and 'scope' parameters. In the examples of {set} however, it does. Did you simply 'search and replace' all occurences of {let} in the documentation, or do some parts of the manual need an update?

      {set} is not {def} ;).

      Namespaces are supported by the set function but not by the def statement as mentionned in the documentation.

      In other words, you can define a variable and set a value for a specific namespace.

  • either? what if undefined?

    "..variables that previously have been declared using either the "def" function." - either def or what?

    And more importantly, what if variable is previously undeclared?

    According to this bug report : http://ez.no/community/bugs/weird_behavior_or_bug_on_set_statement
    You can't {set} array values or object attributes.

    Eg: {set $object_parameters['link_to_image']=true()}
    is *not* valid (at least in 3.6.2). Bummer.
