'sort' uses 'cmp'; so effectively you are asking for string's cmp to be case insensitve. Can you demonstrate a case-sensitive collation function that is as simple as your case-insensitive one: def _default_sort(x,y): return cmp(string.lower(x),string.lower(y)) I see your point. I guess cmp is implemented in C? How about a third optional argument? def _case_sensitive_sort(x,y): return cmp(x,y,string.CASE_SENSITIVE) def _default_sort(x,y): return cmp(x,y) 3.

Re: [Zope-dev] Allowed characters in Zope ids
I recently read RFC 2396 which defines the generic URI syntax
and especially the URL syntax.
I recognized, that
* Zope forbids many characters in ids (with the error message
"not allowed in URLs"), that are legal characters
in URL path segments:
generally allowed in URL's: -_.!~*'()
Zope accepted:_. ~
- as well (see regex below)
, is allowed in the id, sorry not sure what the term path segment means..
allowed in path segments: :@=+$,
Zope accepted: ,
This, probably, is not a big problem.
But, it would be easy to fix.
Except for the fact that Zope also checks that the first character is not a
_. Thats a big security headache. To be honest Im not so worried about Zope
being more restrictive.
* Zope allows space characters in (ObjectManager) id's.
The space is not a valid URL character.
Zope forbids spaces in property ids.
This one is much more important in my mind. Its a real pain. Is there a good
reason for this. It should be easy to fix, actually looking at the regex in
Object Manager, shouldn't that just be a case of taking the space out of the
end of the regex?
ObjectManager.py
line 112: bad_id=ts_regex.compile('[^a-zA-Z0-9-_~\,\.]').search]
On a more anal note could we also patch ObjectManager to tell the user what
characters aren't allowed eg:
line 224: 'The id "%s" contains characters illegal in URLs.' % id
should be
line 224: 'The id "%s" contains characters illegal in URLs. Only characters,
digits and the characters ~-_,. are allowed.' % id

Re: [Zope-dev] Objects with multiple parents and storage flexibility, ZPatterns?
Hi Chris, Random thoughts follow. ;-) I think that if you make your DataSkins folderish it will be hard to make the storage anything other than ZODB. However, Steve Alexander posted a neat trick the other day where __bobo_traverse__ is supplied by an attribute provider. You could use this to make your DataSkins traversable. Let's say your objects have an attribute that defines them in the context of their parent (e.g., dataskin2 in your example URL), let's call it 'context_id'. You may have six objects with the same context_id, but they would all have different parents. Now.. you could implement a search interface that finds an object in context. GetObjectInContextOfParent( context_id, parent_id ) Each object must also (of course) have a parent_id, unless it's a root level object. In SQL this might be: select * from objectXs where parent_id = 'dataskin1_id' and context_id = 'dataskin2' or it could be a catlog search, if you're in ZODB. Now for the traversal interface: def __bobo_traverse__(self, REQUEST, name): ob = getattr(self, name, _marker) if ob is _marker: ob = self.GetObjectInContextOfParent( context_id = name, parent_id = self.id) if ob is not None: return ob raise 'NotFound' return ob Totally untested of course. ;-) Anyway the idea would be to *not* use folderish DataSkins, but to build a hierarchy out of them that could be traversed. -steve ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

[Zope-dev] Frozen Zope?
Has anyone tried to use the "Freeze" utility on Zope? How about Gordon McMillian's"Install" application to make a self-contained Python-Zope executable for Win32? My goal is to create a very easy install of Zope that consists of one or two files. For some of my clients this seems less intimidating on their machines (they would rather not see the "source code", just an executable). Do you think this is possible? Thanks

CS Finally I managed to get a basic understanding of how to do CS things with ZPatterns ;-) So seems quite cool :) (and CS hopefully I find some time to write some basic howto about it) CS But I have some little questions: CS 1. Is it possible to retrieve the set of known IDs from a CS specialist? Or would I need to add my own method to it which CS does this (and change it accordingly if I switch to another CS storage method)? If you store persistently you can use the Rack's method: "defaultRack.getPersistentItemIDs()" Thanks, also found this out in the meanwhile. but a couple of notes: 1) this returns a BTree object, not a simple list, so you can't iterate through it in DTML. You'll need to copy it to a simple list for that.. and 2) If you change to a different storage you'll need to create your own method (ZSQL Method?). What I've found is that if you have a large number of objects you'll either want to query a Catalog, or an SQL database to get Ids that match some criteria that limit the number of hits to something that makes sense to display in a browser. I am now using some method I create inside the specialist for it. CS 2. Is it planned to provide something like a virtual folder CS which acts like a normal object manager but is controlled via CS ZPatterns (so actually something like Folder with Customizer CS Support just without the "anchor" in ZODB. (would also CS require some mechanism asked for in 1.) Hmmm... I'm not sure what you're after here. Why not just use a Specialist? In what sense do you want it to be virtual? Well, virtual in the sense as a specialist is no real folder but can provide content from different sources. Thus what I mean is some mechanism which emulates objectIds() etc. so it looks to the user (and the ones using it via dtml) like a normal folder object. Somehow like the Customizer but without the need for actually creating Zope objects. Something inbetween Specialist and Customizer this would be I guess. (Are you looking for a dynamic traversal interface that would allow you to map URLs to objects that are managed by ZPatterns? Can you give an example?) yes, something like this comes close I guess. e.g. I have some sql database consisting of people's addresses and I want to create some specialist which queries this database (or how ever this specialist is configured right now in order to get the object ids) and shows it as if it's a normal folder. (seems to me more transparent at some point). But I assume it's not suited for all applications e.g. if the number of objects gets a little bigger. And I guess I can create this myself if I subclass from Specialist and add the rest of the ObjectManager's interface to it. CS 3. Is it possible to use ZPatterns also without some exta CS ZClass defined in a Product? At least if I don't need methods CS for my objects but simple want to define the attribute they CS know. Would be nice as I could then hold everything together CS in one place (the specialist that is) without requiring to CS install something also in the Products folder of the Control CS Panel. I believe you need to either create a Python subclass, or a ZClass subclass of DataSkin. "Raw" DataSkins don't have the right permissions to allow for TTW access. If you're creating a 'product' anyway... just make a 'dummy' class that you can use for storage. ok, but I still need to define the attributes I want to handle inside a propertysheet of this ZClass, right? Actually what I would like is something which directly resides inside the Specialist and not somewhere outside in some Product folder. So everything is close together in one place.

Re: [Zope] Zope Projects in NL/Europe?
(Writing from the Netherlands) Just wondering: are there any Zope projects are available in the Netherlands/Benelux/Europe? We did one last year but they seem hard to find. Are there commercial projects available or is Zope mostly used on internal projects? Is there any demand for Zope expertise around here? From the (spontaneous) requests I have had over the last year about Zope expertise, I can assure you that there is plenty of demand for Zope expertise. The problem is mainly that it is harder to find (commercial) expertise than to have projects available. Zope not (yet) being such a widespread Web developing alternative, needs are less visible. We are using Zope in our institution and there is too much work for me to handle, but I have had a hard time finding developers who can help me out. I'm sure this applies to more institutions and companies in the Netherlands (and Belgium for that matter). And, btw, not to be nitpicking, but how would people know you have Zope expertise? Is it in your company profile, are you on the Zope service provider page, have you offered your services somewhere visible. The second point is of course that you could also prove Zope to be a viable alternative over other web developing tasks, by just doing projects in Zope. Or are all you customers asking for applications in specific technologies rather than solutions with the highest quality/for the best price/in the shortest time possible? Reason I'm asking is that I'd love to continue working with Zope, but it's hard to justify in a company focused on Microsoft and Oracle, especially if there is no money to be made. I can learn Perl on company time and Linux is our internet server OS of choice, but JSP/Java and .NET (the latter is not that bad, uses SOAP/XML-RPC) is next if we don't find a use for our Zope expertise.

It would be nice, if there were some declaration telling the acquisition machinery about this fact. I do not know, whether there is such a mechanism. If it is, then some Zope developpers did not know about it. To prevent acquisition, many Zope objects provide new definitions for the unwanted attributes. For example, "SimpleItem.Item" defines "objectValues" (and friends) to prevent them from being acquired from the containing folder. This hack does not play well with inheritance, however! If in your case, "PortalMember" provides empty "object*" methods, the correct "ObjectManager" methods will not be found. You may try to switch the inheritance order. However, I fear, the problem is already in "ZObject", the order of which can not be changed. Hope, that in some future time, this hack disappears.

[Zope] objectValues Question
Hi,
I'm new to Zope and while 'playing' around I wondered about the following:
I've created a DTML method (called MyListFiles) that lists the 'File'
objects contained in a folder:
ul dtml-in "objectValues('File')" lia href="dtml-var
absolute_url"dtml-var id/a/li /dtml-in /ul
This works as expected when I run it using the 'View' tab.
Now when I create a DTML document and call this method like this:
dtml-var MyListFiles
it produces no output.
Why?
Thank You for any help

RE: [Zope] objectValues Question
By applying your MyListFiles method within the context of your DTML Document
you are asking for files that are contained by your DTML Document and there
are none. By 'viewing' your method in the management interface you are
applying your method within the context of the folder that contains it, and
that folder apparently contains file's. If you want to use your method
within a DTML Document with the very same result you could use for instance:
dtml-in "PARENTS[0].objectValues('File')"

Subject: [Zope] objectValues Question
Hi,
I'm new to Zope and while 'playing' around I wondered about the following:
I've created a DTML method (called MyListFiles) that lists the 'File'
objects contained in a folder:
ul dtml-in "objectValues('File')" lia href="dtml-var
absolute_url"dtml-var id/a/li /dtml-in /ul
This works as expected when I run it using the 'View' tab.
Now when I create a DTML document and call this method like this:
dtml-var MyListFiles
it produces no output.
Why?
Thank You for any help

If you try to get them from a DTML Document, it will not return anything, as the DTML Document holds no other objects. The solutions is to make the DTML Method call its parent's (=containing object) objectValues.

Thank you,
...for your tip with the PARENTS[0].objectValues('File')
Please let me ask your advice on how to realize the following:
I would like to build an application for handling development requests.
These requests should be submitted by our end-users through our Intranet to
my team. We then look at each new request and dispatch it to one or more
development team for approval (or rejection). At this stage:
- The end-user should be able to see that his request has been dispatched
- The concerned development team(s) should see that there is a new request,
they could look at it and accept it or reject it and give a comment
When all the teams have replied, my team would add a summarized comment to
the request and the end-user should be able to see this. At this point, the
request handling for my team is at its end.
Requests should be submitted by a Web-Form and may contain an arbitrary file
(eg. Word Document).
The end-user and the development team should see only what they are
concerned with.
My team needs a global overview.
Do I need a database or would basic Zope objects work? Where to begin? I
feel that there should be a 'Request' object (document or method?) with a
few methods for adding, dispatching, ...

[Zope] Leaking Oracle connections processes
Hi guys, We are trying to build a site with Zope and Oracle, and we see again and again a situation where Oracle connections and processes are being leaked: the more we work, the more there are, until we reach Oracle's limit for number of processes. At this point, the Connection objects close on their own, and you can't even open SQL*Plus until Zope is closed or restarted. We use Oracle's default limit on the number of processes, which is 50. We have about three users (developers), two Oracle connections in the application (one for SqlSessions and one for other data), and although we use some devious multithreading (some of our transactions call an external method which essentially URLRetrieve()s a URL from our own Zope server in a separate thread), 50 open connections should be more than enough. I have checked a little before the disaster, and it seems that not all those processes actually have connections; the problem may be unrelated to open connections, but just to processes. We do one fishy thing that may also be related: We keep some long raw data; we keep it all in one table, and other tables which need long columns hold pointers (indices) into this table. To put data into this table from Zope, we use an external method SaveLONG, which uses the database connection to access the DB (in order to use the transactionality of the whole thing). We use it in ZSQL methods as follows: INSERT INTO items ( field, long_field_ptr ) VALUES ( dtml-sqlvar value type=string dtml-var "SaveLONG(DB_CONNECTION, long_value)" ) SaveLONG saves the long value in the long data table and returns its index in the table. The source for SaveLONG is this. It relies on a DB trigger to populate the LONG_ID field from a sequence. long_table_name = 'LONG_DATA' long_column_name = 'LONG_DATA' long_seq_name = 'SEQ_LONG_DATA' index_column_name = 'LONG_ID' save_command = ''' INSERT INTO %s (%s) VALUES (:content) '''% (long_table_name,long_column_name) get_key_command = 'SELECT %s.currval FROM dual' % long_seq_name # # Put a long raw on the DB # def SaveLONG(self,connection, content): connection = connection._v_database_connection.db # the real DB connection object connection.execute(save_command, content=dbi.dbiRaw(content)) connection.execute(get_key_command) return connection.fetchone()[0] We're using Zope 2.2.4 with ZOracleDA 2.1.0 and DCOracle 1.3.2 with Oracle 8.0.5 on an intel-linux (RH). Can anyone see anything wrong with what we're doing? Is anyone else experiencing this kind of problems?

[Zope] Problem with SiteAccess
Hello, I'm trying to use the SiteAccess Product as discribed in the HowTo: Using Apache with ZServer (NOT Zope.cgi). Unforunately things don't work as described. My ZServer is listening on www.myserver.com:9080/somesite. I would like to be able to access the ZServer through apache via the URL www.somesite.com (to do virtual hosting). The ProxyPass directives work well (the pages get served properly), but the URL's in my pages still contain the complete URL's of the ZServer, like img src="http://www.myserver.com:9080/somesite/images/some.gif" instead of img src="http://www.somesite.com/images/some.gif". The same is true for normal links. Ok, it's not so bad, things work (no broken links), but it is a little bit ugly. I thought the SiteAccess Product should handle these problems, by putting a SiteRoot object in the somesite folder. Or do I have to write an AccessRule ? And how would that look like ?

RE: [Zope] Advice on searching/indexing Word documents?
I really like the idea of extending OFS:File to support different file types, but what I would like to see is something that is format/filter/library agnostic. That is to say, that perhaps the way we ought to go about this is to create an API framework that upon upload filters the file with a specified filter for its mime-type. Perhaps creating a generic base class that implements a generic API for filtering a file, from which to extend by inheriting more specific classes for files of particular types or groups (fine grained to mime-type or grouped in category, eg. "Illustration"). Having such a generic framework would enable Zope to be an excellent platform for digital asset management; Suppose you had a class for all files for a particular purpose, and those files would always be of a partiaular set of mime-types, like Illustrator, PDf, or postscript. For example, if someone working at a newspaper creates a new file class instance called "DisplayAd," which is used for postscript files with embedded fonts, containing specific text, a filter set up as part of the extended class for DisplayAd file would detect the type of file, determine it was PDF, and filter out the text, and the face names of the embedded fonts. If the file was a PDF or an AI file, it would then run the appropriate filter. It might also be nice to have a extended class (inherited from file) that works for all types, and keeps some sort of configurable plugin registry of sorts, so that we can create plugin classes for specific mime-types, but only have to use one class for the objects themselves. This might be more practical. One thing that seems important: creating an API like this could allow us to write filter "plugins" in a variety of Zope supported configs, like completely in python, a python class extending a C shared library, something written in a combination of C/Lex, or the python-based plex scanner that was mentioned earlier - for that matter, even proprietary user-space binaries called via python code might be fair game... I really think that this idea has potential as a project, and would be willing to contribute.

from DTML, so the "ob.attr = val" idiom is out from the get-go. Another
assumption I'm making is that "there should only be one way to do it". I'd
rather not have both __setattr__ and .set work for session data objects,
because it's confusing and doesn't buy anything at all other than a couple
keystrokes.

Yes. That's what Bob S. suggested. What are the benefits of this?
More graceful code that's more 'pythonesque' in Python Scripts:
if sessionmanager.SessionData.a['mykey'] == 1:
...as opposed to...
if sessionmanager.SessionData.get('a')['mykey'] == 1:
The current way is:
if sessiondatamanager.getSessionData()['mykey'] == 1:
.. do something...
I suppose you'd rather see:
if sessiondatamanager.getSessionData().mykey == 1:
.. do something...
Is this really worth it?
sessionmanager.SessionData.b = 1
...as opposed to...
if sessionmanager.SessionData.set('b',1)

Re: [Zope] Problem with SiteAccess
* Leonardo Graf ([EMAIL PROTECTED]) [010103 09:16]: Hello, I'm trying to use the SiteAccess Product as discribed in the HowTo: Using Apache with ZServer (NOT Zope.cgi). Unforunately things don't work as described. My ZServer is listening on www.myserver.com:9080/somesite. I would like to be able to access the ZServer through apache via the URL www.somesite.com (to do virtual hosting). The ProxyPass directives work well (the pages get served properly), but the URL's in my pages still contain the complete URL's of the ZServer, like img src="http://www.myserver.com:9080/somesite/images/some.gif" instead of img src="http://www.somesite.com/images/some.gif". The same is true for normal links. Ok, it's not so bad, things work (no broken links), but it is a little bit ugly. I thought the SiteAccess Product should handle these problems, by putting a SiteRoot object in the somesite folder. Or do I have to write an AccessRule ? And how would that look like ? Thanks a lot, regards, Leonardo Graf It sounds like your SiteRoot object doesn't have "Base" (aka the Base URL) set correctly. It should be set to: http://www.somesite.com The SiteAccess Rule is only needed if you have *multiple* hosts served out from one host. You sound like you only have one.

[Zope] Using a multiple_selection property in a product

However I am having problems getting the product to correctly recognize
a multiple selection property. The property is the days of the week that
the course is offered. ( Monday-Wednesday-Friday or Tuesday-Thursday, or
any combination thereof)
The DTML for the product creation form contains the following:

td align="LEFT" valign="TOP"
select name="classdays:multiple_selection" size=5 multiple
option value="Monday"Monday/option
option value="Tuesday"Tuesday/option
option value="Wednesday"Wednesday/option
option value="Thursday"Thursday/option
option value="Friday"Friday/option
/select
in the product class I have tried two tactics (actually more but I'll
confess to only these two)
_properties(
{'id':'classdays',
'type':'multiple_selection','mode':'w'}, ...
RESULT: product installs, but classdays in an "unknown property type"
so I try this:
_properties(
{'id':'classdays', 'type':'multiple
selection','mode':'w'}, ...
RESULT: product installs, however the Properties are unavailable,
furthermore trying to view the properties by clicking on the Properties
tab generates the following Zope error:

Re: [Zope] Core Session Tracking kudos namespaces
You're right, Dieter. I was thinking in Python terms and forgot about DTML namespace lookup rules. :-( Yes, if we had a __getattr__ interface or used the mapping keyword on the return value of a __getitem__-based session data object, and if the name was not found in the namespace that is put on the DTML stack by "with sessiondataobject", it would then be looked up in the form and cookies namespaces, then it would attempt to be acquired, etc. Sorry for the misinformation. So the question becomes: do we want DTML namespace lookup magic or no DTML namespace lookup magic for names that we attempt to look up in a session data object? I don't know the answer. I'm so sick of magic at this point that I'm apt to vote "no", but if it affords us some provable real-world benefits, I could change this vote. If someone would be kind enough to give me an example where having DTML namespace lookup magic for names out of a session data object would be very useful, I'd consider it carefully. - Original Message - From: "Dieter Maurer" [EMAIL PROTECTED] To: "Chris McDonough" [EMAIL PROTECTED] Cc: "Bob Sidebotham" [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Wednesday, January 03, 2001 4:50 PM Subject: Re: [Zope] Core Session Tracking kudos namespaces Chris McDonough writes: Currently, nothing would be acquired, and the dtml-var a call will fail inside of a "with sessiondatamanager" even if we did have a __getattr__ interface to session data objects Are you sure?

th align="LEFT" valign="TOP"emDays Course Offered/em/th
td align="LEFT" valign="TOP"
select name="classdays:multiple_selection" size=5 multiple
option value="Monday"Monday/option
option value="Tuesday"Tuesday/option
option value="Wednesday"Wednesday/option
option value="Thursday"Thursday/option
option value="Friday"Friday/option
/select
in the product class I have tried two tactics (actually more but I'll
confess to only these two)
_properties(
{'id':'classdays',
'type':'multiple_selection','mode':'w'}, ...
RESULT: product installs, but classdays in an "unknown property type"
so I try this:
_properties(
{'id':'classdays', 'type':'multiple
selection','mode':'w'}, ...
RESULT: product installs, however the Properties are unavailable,
furthermore trying to view the properties by clicking on the Properties
tab generates the following Zope error:
Error Type: NameError
Error Value: select_variable
[somewhat helpful troubleshooting suggestions]

I've also tried to use :list with much less success. Any helpful
suggestions would be appreciated. The solution is not obvious to me.

[Zope] Poor Procedural Programmer Needs OOPish Enlightenment
or... "A Cry for Namespace Help" I seem to have run into one of those Zope namespace issued that's starting to make me dizzy. I have a index_html method that displays content conditionally depending on where it's called. It looks like this: dtml-if expr="PARENTS[0].id != 'edit'" dtml-var index.html dtml-else dtml-var chunk_editFrameset /dtml-if The chunk_editFrameset method also displays the same index.html file in one of two frames. This works like a champ. If I'm in a directory called edit when this is called, it displays the frameset. Otherwise, it displays the index.html directly. The index.html method is contains a bunch 'o static html plus another method called chunk_dspPrimaryCol that also conditionally displays information based on where it's called. chunk_dspPrimaryCol looks like this: dtml-if expr="PARENTS[0].id != 'edit'" dtml-var chunk_dspPrimaryColPublic dtml-else dtml-var chunk_dspPrimaryColEdit /dtml-if This doesn't work like I'd hoped, since I have to move back up the namespace stack to find index.html, and by the time I do I'm no longer in the edit folder. So I _always_ end up displaying the chunk_dspPrimaryColPublic method, even if I call the index_html method from within the edit folder. What I need (I think) is a way to keep all of this activity in the edit Folder. Or I need some other way of solving this problem. Any thoughts?

[Zope] A bug in Membership product? (member password can be revealed by dtml method accessible by anonymous)
Hi Bill,
A dtml method with these lines:
dtml-with "acl_users.getItem('z')"
dtml-var password
/dtml-with
will show the password, despite that the methode is accessible by anonymous. Members in
my site is allowed to use dtml method. How can I prevent them from reading others'
properties?

RE: [Zope] Poor Procedural Programmer Needs OOPish Enlightenment
Not sure if this is your problem, but since methods don't have namespaces, I'm not sure why your code could not be reduced to: dtml-if expr="id != 'edit'" dtml-var index.html dtml-else dtml-var chunk_editFrameset /dtml-if The namespace of index_html right now is 'edit' (or another folder that acquires it) ...and... if the namespace of index_html is 'edit' than the namespace of index.html will also be, and ergo, the namespace of chunk_dspPrimaryCol will also be edit (index.html doesn't have a method unto itself), changing your code to: dtml-if expr="id != 'edit'" dtml-var chunk_dspPrimaryColPublic dtml-else dtml-var chunk_dspPrimaryColEdit /dtml-if Just keep in mind, that any object with a namespace (folders, documents, certain class instances) that is in the acquisition path can have that namespace explicitly invokes with dtml-with name_of_object. This only works for object with a namespace; methods are not acquirable objects, and though you might call them objects (in a loose sense) they are not objects in a Zopish sense. I don't know if my sugestion will work for you, but hopefully it will help.

[Zope] [Newbie] ZSQL problem
Hello all. I'm a total newbie to Zope (a few days). I have a problem with getting some results throuh a ZSQL method. (I've been playing with a sample baseball database that came with PyGreSQL.) I have a form that accepts multiple choice: (generated by the wizard) form action="search_data_result" method="get" trthHome team/th tdselect name="home_team" size="10" multiple option value="Indians"Indians/option option value="Blue Jays"Blue Jays/option option value="White Sox"White Sox/option option value="Red Sox"Red Sox/option /select input type="SUBMIT" name="SUBMIT" value="Submit Query" /td/tr /table /form My ZSQL method, called get_all_from_game is the following: select * from game where home_team= dtml-sqlvar home_team type=string and I have specified 1 argument: home_team -- the output page: search_data_result looks like that: (it's been generated by the wizard) dtml-in get_all_from_game size=50 start=query_start dtml-if sequence-start dtml-if previous-sequence a href="dtml-var URLdtml-var sequence-query query_start=dtml-var previous-sequence-start-number" (Previous dtml-var previous-sequence-size results) /a /dtml-if previous-sequence table border tr thHome team/th thVisiting team/th thHome team runs/th thVisiting team runs/th thGame date/th thGame number/th /tr /dtml-if sequence-start tr td bgcolor="#A6A6A6"dtml-var home_team null=""/td tddtml-var visiting_team null=""/td tddtml-var home_team_runs null=""/td tddtml-var visiting_team_runs null=""/td tddtml-var game_date null=""/td tddtml-var game_number null=""/td /tr dtml-if sequence-end /table dtml-if next-sequence a href="dtml-var URLdtml-var sequence-query query_start=dtml-var next-sequence-start-number" (Next dtml-var next-sequence-size results) /a /dtml-if next-sequence /dtml-if sequence-end dtml-else There was no data matching this dtml-var title_or_id query. /dtml-in --- When I select one item in the list I get the results as specified in the SQL query.

This is rendundant. ISO-8859-1 is the default encoding for http,
anyway, and has ever been.

And I figured out my problem while yanking out another unneeded reference to PARENTS. In my framset code I had a reference to PARENTS[1] (not [0]!), so I was forcing Zope to look at the index.html method from the namespace of the test_site folder. DOH! Zope is a funny thing -- it makes some things so much easier, but I always find myself getting tangled up in stooopid namespace problems of my own making. I guess I'm just not used to thinking this way yet. Many thanks for the assist.
