[Zope] Re: Defining a dictionary in ZPT?

[michael nt milne]

ok, thanks Duncan

<ul>
<li tal:define="query nocall:here/testquery" tal:repeat="result
python:query(id='IT')">
<span tal:replace="result/lastname">lastname goes here</span>

</li>
</ul>

works! I went down a blind alley with calling the database adapter due to
confusion over the error message produced. Backs up my point about more
friendly and usable error messages.

Much appreciated!
