I (finally) got my permissions problem with my external method solved, by changing the ext method to return a list of lists:

def getAll: rows = ... # get data from soap call results [] for row in rows results.append( row[0], row[1], row[2] ) return results

this gets the data and returns it in a list of lists: [['1', 'Fido', '5.00'], ['2', 'Spot', '10.00'], ['4', 'Sparky', '24'], ['9', 'Buffy', '10'], ['10', 'Bobby', '50']]

my tal code looks like the following:

<p tal:content="here/getRecords"> </p>

<table border="1" tal:define="data python:here.getRecords()"> <tr tal:repeat="record data"> <td tal:content="python:record[0]">record item 1</td> <td tal:content="python:record[1]">record item 2</td> <td tal:content="python:record[2]">record item 3</td> </tr> </table>

Neither of the above work... on both counts, now I get:

------------------------------------------------------------------- Exception traceback Time 2003/06/30 15:32:49.218 US/Eastern User Name (User Id) Anonymous User (None) Request URL http://jhoodxp.hmcon.com:8081/jhood/show_records Exception Type TypeError Exception Value sequence index must be integer

Traceback (innermost last): ... TypeError: sequence index must be integer -------------------------------------------------------------------

It seems (to me with my limited python/zope knowledge) that the tal is looking for something other than a list of lists, and it can't handle it... although now at least I don't have security issues...

Question is... what can I do ??? If I have to change the return value, what should it be, and if I can use it, how can I use it with tal...

It works for me when I use the list representation you gave as the return value of a Python Script, suggesting that the problem is not in the display. It may be because of a typo in your external method, which should say:: results = [] Notice the 'gets'. Make sure you're returning what you think you're returning. If that's not it, you need to take a good close look at that traceback. The problem is probably exposed in /jhood/show_records around line 34. Is that where the code you show above came from? Trace back where you got 'item'. Fyi, I can also do:: <table border="1" tal:define="data python:here.asdf()"> <tr tal:repeat="record data"> <td tal:repeat="elt record"><span tal:replace="elt"/></td> </tr> </table> --jcc

Strange that this works. I would expect a "TypeError: 'append' takes a single argument".

TypeError: sequence index must be integer

Your code extract does not correspond to this traceback. In line 34 of "show_records" you use "records/item" (which does not occur in your code extract). There, "records" is a sequence but 'item' is a string. This results in the TypeError you observe. Unless you access the built in methods of a sequence (e.g. of a list), you must use "python:" expressions to access sequence components. Dieter
