Hi everyone,
I'm using Zope with OpenFlow for a workflow. The problem I'm encountering now
seems to be entirely related to Zope; actually, a particular value for a
parameter generates the error, so I'm guessing there's something wrong with the
data, not the script.
There's a "browse" file defined in the workflow, with the following first lines:
<html><body>
<html>
<body tal:define="results here/Catalog;
qq request/QUERY_STRING;
qs python:container.stripStart(qq);
start request/start|python:0;
batch python:modules['ZTUtils'].Batch(results,
size=20,
start=start);
previous python:batch.previous;
next python:batch.next">
Now, if I call this script with no parameters in the URL, it shows all
documents. If I append a ?issuer=john.d parameter to the URL, only documents
issued by john.d will be displayed. This works even for fictive names,
displaying a blank table as a result. However, for a particular user (and only
that one), I'm getting this error:
Error Type: TALESError
Error Value: exceptions.KeyError on -1882874846 in "<PythonExpr
modules['ZTUtils'].Batch(results, size=20, start=start)>", at line 3, column 3
In the page source, this is the detailed debug information:

Unfortunately, all this is worse than Chinese to me. Any clue where the error
may be, and what to do to fix it, please?
Many thanks in advance!
