www.zope.org product list request . . .
by Christopher J. Kucera 23 Mar '00

23 Mar '00

A simple request: Could the Product list at zope.org be alphabetized? Every time I go there to find a product, I end up having to use the "find" feature in my browser. Not a big deal, of course; just a suggestion. Thanks! -CJ

timing error in ZODB lock?
by Garry Hodgson 23 Mar '00

23 Mar '00

i'm getting some funny behavior using a (separate from Zope's) ZODB from External Methods. after much thrashing, i've got my application working. however, every so often, when i click on a submit button that invokes an External Method, i get: Could not lock the database file. There must be another process that has opened the file. the odd thing is that if i click the browser "back" button, then hit my button again, it works. occasionally i need do this back/resubmit thing more than once, but usually once suffices. smells like a race condition to me. has anyone else seen this, or have an idea how i can avoid it? -- Garry Hodgson Every night garry(a)sage.att.com a child is born Software Innovation Services is a Holy Night.

records form variable type
by John Williams 23 Mar '00

23 Mar '00

I have been using the records form variable type, but believe there may be a problem with it. With most browsers all appears OK, however some browsers (e.g. Mozilla) may return form elements out of order. What this means is that when trying to use the records type their is no guarantee that the different elements of a single record will be sent consecutively and therefore the records objects will not be correctly constructed by Zope. I would like to know if this is the fault of browser or if this is an issue which excludes the general use of the records type. If the latter what alternatives would be recommended - I would prefer not to have to create unique form element names as it would add a fair amount of complication. What guarantees can be safely assumed about data arriving from a form - for example if you try using the list type is the order in which the components of the list guaranteed to be the same as the order in which the respective form elements occur in the document? -- Dr. John A.R.

Changing Roles
by Chris Withers 23 Mar '00

23 Mar '00

Hi, A simple question, but getting a bit irritating... How can I change the roles assigned to a user without knowing their password? The form to do this has password fields which come up blank, and you can't submit the form without filling them in. I don't want to know what the user's password is anyway, I just want to change the assigned roles... ;-) HSCH, Chris PS: Zope 2.1.4 and 2.1.6...

redirects in standard_error_message
by John Chandler 23 Mar '00

23 Mar '00

My saga with the standard_error_message continues ;-) I'm trapping 404 errors for missing pages, checking the intended URL against a list of URLs which have moved to new locations and returning a link to the new location as part of the error page. What would be useful would be to automatically redirect to a new URL if it occurs, but this is proving a problem. I've been using RESPONSE.redirect() as this has proved useful on other pages, but on standard_error_message this doesn't appear to have any effect - even when the entire contents of the error page is stripped out and replaced by just the call to redirect(). Is it possible for standard_error_message to handle redirects (in which case, what else do I need to do?) or is there another way to go about this? Thanks in advance.

Welcome Aboard Matt Burleigh!!
by Rob Page 23 Mar '00

23 Mar '00

Hello everybody! Please join me in welcoming Matt Burleigh to the Digital Creations team!! Matt joins us as our first (and sorely needed!) system administrator. >From Matt's man page: """ I call beautiful and historic Fredericksburg, Virginia my /home. Fishing, hunting, and reading civil war history are my hobbies. Don't tell anyone but I've taken many tech support calls from a boat and even lost a cell phone in the lake once. In 1983 I got a 1200 baud modem for my 64k IBM PC and it was down hill from there. Sometimes I feel like I spent all of my life in front of a computer. I started the first BBS in the Fredericksburg area and a quite successful one. Eventually becoming Central Virginia mail hub for FidoNET and sucking Usenet newsgroup feeds off of a satellite dish then divvying it up for the local area SysOps. Those Usenet feeds were from this thing called the Internet, which took me by suprise in 1994. At the time I was running a small computer sales and service shop in the area. Once I realized that BBS's and RIP Script (a graphical language for BBS's that was going revolutionize the online world, ha!) wasn't going to make it, we switched our dial-up modems to direct connections to ISPs. In 1996 a friend of mine introduced me to Slackware Linux. This crude operating system really intrigued me and I found it to be an exciting new challenge. A couple months later I began selling used machines with IP masquerading and firewall setups. Soon after that, I convinced a customer of mine to switch from the ever failing Windows NT v3.51 to Linux. The system ran for over 6 months with not one problem or required reboot. I was hooked and swore never to install Windows NT again. """ Matt can be reached at: mailto: mattb(a)digicool.com Welcome Matt! --Rob -- Rob Page V: 540.371.6909 Digital Creations, Inc.
