There may be a nicer way of doing it, but you can access the outerlist by using _.namespace to insert the orignal value of sequence-item into the DTML namespace as a new variable. In situations where you've got '-' in your name, you can always use _['sequence-item']
I see. I have the feeling, that the expr="..." stuff was invented later in the design. And therefore those 'dirty tricks' are necessary: <!--#with "_.namespace(outeritem=_['sequence-item'])"--> It is very contra-intuitive for me. This looks absolutely 'grown' to me and not designed (no critique, must good systems start like this). I guess this was the sequence of events: - 'var' and 'in' were the first supported tags - Good idea: use '-' in special names to make sure there is no name clash! Cool! - Oh! But we need expressions. 'expr=' was added. - Gash! We need namespace manipulations: OK, lets use expr and the special name _ for the namespace itself. Hey cool, we can use keyword args: expr="_.namespace(name=var,name=1+4)" - Oh shit! what should we do with the special variables? OK let's access them with ['special-name'] -> <#with "_.namespace(outeritem=_['sequence-item'])"--> Understandable, but still *very* ugly...
