[Zope-dev] manage_changeProperties in a loop

[Arno Gross]

If I try your suggestion wiht _.getitem(_['sequence-item']) 
(If I remember well this was the first I tried).

<dtml-call "REQUEST.set('rangList','folder1;folder2;folder2')"> 
<dtml-in " _.string.split(rangList,';')"> 
   <dtml-with "_.getitem(_['sequence-item'])"> 
    <dtml-let index=sequence-index>
      <dtml-call "manage_changeProperties({'rang':index})"> 
    </dtml-let>  
  </dtml-with> 
</dtml-in>  

I get this error: File
D:\packages\Zope\WEBSIT~3\lib\python\DocumentTemplate\DT_In.py, line 691, in
renderwob     (Object:  _.string.split(rangList,';'))   File
D:\packages\Zope\WEBSIT~3\lib\python\DocumentTemplate\DT_With.py, line 133, in
render     (Object: _.getitem(_['sequence-item']))   File
D:\packages\Zope\WEBSIT~3\lib\python\DocumentTemplate\DT_Util.py, line 337, in
eval     (Object: _.getitem(_['sequence-item']))    (Info: _)


Still any hints. Thanks.
