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.

Suppose I have a list of existing folder objects and depending on their index in the list I want to set a property called 'rang'.

I assumed you could something like this:

<dtml-call "REQUEST.set('rangList','folder1;folder2;folder2')"> (normally the list comes from outside)

<dtml-in " _.string.split(rangList,';')"> <dtml-with "_.getitem('sequence-item')">

Here, you're getting an item with the literal id 'sequence-item'.

What you mean is to get the item with the id described by the variable sequence-item. So, use:

<dtml-with "_.getitem(_['sequence-item'])">

Hope that helps.

This really is a zope@zope.org question, not a zope-dev@zope.org question. Please do try to choose the appropriate list for the question. Thanks.

Also, why are you passing the folder ids in a string like this? Where are these names coming from, a form?

Yes, the names are coming from a from where I can sort the folders for showing in the desired order. I know that I can use a list with a SELECTION tag. But will get only the selected options and I need all the options in the ordered sequence. Of course I could select programmatically all options before returning the form and then I could work the list. But how can I pass the objects instead of the string? Best wishes Arno Gross, arno.gross@consotec.de

If so, there are ways to eliminate the whole string.split. Also, the code would not need to be this complex if the objects themselves can be > passed instead of a delimited string of ids. -- | Casey Duncan | Kaivo, Inc. | cduncan@kaivo.com `------------------>
