IE 5.5 "Warning: Page has Expired"
by Paul Smith 12 Apr '01

12 Apr '01

Dear all, Not exactly a Zope question, but something that has been driving me nutty over the past few weeks whilst using Zope. I am using IE 5.5, with Zope 2.3 on WinNT 4.0. The 'problem' is, that after merrily editing away on some lengthy DTML Documents, I click on 'Save Changes'. Damn - I forgot to close out one of the <dtml-if> statements, so my page has not been saved. Click 'back'... ...but instead of the lovely DTML I was just working on, I get: "Warning: Page has Expired The page you requested was created using information you submitted in a form. This page is no longer available. As a security precaution, Internet Explorer does not automatically resubmit your information for you. To resubmit your information and view this Web page, click the Refresh button." Obviously clicking the refresh button does not help, as this just reloads the frame set, and dumps me back to the main root directory. I'm guessing that this is some security issue in the browser as I am authenticated whilst administering this Zope installation. Any ideas as to how to get round this (apart from obviously saving the stuff more regularly?) This does not appear to be a problem using Netscape, but for some reason I prefer using IE with Zope.

Re: [Zope] <dtml-in " " size=1> error

Hi there Thanks for the quick response. I tried both suggestions and first gave the same error whereas the second causes some other error. I delved deeper and found my dtml-in tag that gives you the ability to navigate to the next record was missing a next. <dtml-in sqlSelectAllCustomers next size=1 orphan=1 start=query_start> <dtml-if next-sequence> <a href="<dtml-var URL><dtml-var sequence-query >query_start=<dtml-var next-sequence-start-number>"> (Next) </center></a> Thanks for you help Grant >>> Casey Duncan <cduncan(a)kaivo.com> 10/04/2001 16:15:18 >>> Grant Murphy wrote: > > Hi > > When I use the following tag, the result only contains the first and second records > in the postgres table.

Best Method for my app?
by Jeremy 12 Apr '01

12 Apr '01

I am a little confused about the best method to create my Zope application. It will manage a unique part of our business that deals in the medial claims field. It will be tracking claims, patients, providers, etc... Each of these 'Objects' will have add, edit, search and detail screens on them. A lot of the times a details screen will access the other objects, for instance, a provider detail screen will show all the claims and patients associated with them, while a claim may show the person, as well as the provider that the claim is for. Should I just be making folders with Z SQL Methods or using ZClasses? Pardon my simplistic question but I am still somewhat new to Zope and want to make the right choice in the beginning of my development process instead of forcing a re-write later down the road. Thanks! -- Jeremy - jeremy(a)cowgar.com

problem manage_upload
by servel yannick 12 Apr '01

12 Apr '01

Hi all, I have got a problem with the manage_upload methods: I created an uploadImage external method in order to update programmatically. This function works perfectly when I do a simple call to this function like this: if REQUEST["namelogo"]<>'': if self.i.namelogo: self.uploadImage(obj=self.i.namelogo, file=REQUEST["namelogo"]) else: self.addImage(obj=self.i, id='namelogo',file=REQUEST["namelogo"]) def uploadImage(obj,file): f=open('%s' %(file),'rb') f.seek(0) contents=f.read() f.close() title='' tlen = len(contents) new_id = obj.manage_upload(contents) #img_obj = obj.__getitem__(new_id) return '' The problem arose when a more complicated call to this function is made: f = 1 for img in listfile: if REQUEST[img]<>'': if self.i.REQUEST[img]: self.uploadImage(obj=self.i.filename%d %(f) ,file=REQUEST[img]) else: self.addImage(obj=self.i, id=img ,file=REQUEST[img]) f = f + 1 Basically, it says that a string object cannot use the manage_upload method. Any idea?? Thanks in advance, Yannick

M2Crypto+Zope+WebDAV - Unexpected eof
by oliver.erlewein＠sqs.de 12 Apr '01

12 Apr '01

Hello! I'm experiencing Problems with Zope 2.3.1 (WinNT 4) in conjunction with M2Crypto 0.06 snap4 (ZServerSSL) when accessing my Zopeserver via WebDAV with https. When copying files to and from Zope (with IE 5.x or WebDrive) following errormessage is displayed by Zope: 2001-04-10T15:14:36 INFO(0) ZServer recv: closing channel <zhttps_channel connec ted 172.20.16.42:2320 at 1b85c20 channel#: 150 requests:1> unexpected eof The client process (e.g. Eplorer) hangs up and must be killed in the Task-Manager. If I do the same with normal HTTP (no SSL-encryption) all is well. Can anybody confirm the problem? Is there a solution? Any help is welcome! regards, Oliver Erlewein oliver.erlewein(a)sqs.de <mailto:oliver.erlewein@sqs.de>

Re: [Zope] insane Central Daylight Time, Zope 2.2.2
by Anthony Baxter 12 Apr '01

Using the short form of timezone names (e.g. "EST", "PST", &c.) is a good way to get yourself really, really, _really_ confused. Use the fuller 'Australia/Victoria' or 'United States/Pacific' forms. Or just use UTC/GMT. If your system writes down any records with datestamps in them, you may find horrible things happen to you as you switch on and off daylight savings.

RE: [Zope] any known bugs wrt transactions never being committed?
by Randall F. Kern 12 Apr '01

12 Apr '01

Turns out this was a PoPy bug. In particular, PoPy 2.0.2 has a global semaphore it blocks all queries on, including commit and begin. This means if you try to execute a Postgres query that has to block on another transaction (1), you get deadlock, and a hung Zope. -Randy 1: A common case for this is concurrent updates when run in serializable transaction mode (the PoPy way).

Xron changeproperties

Trying to use the following in a DTML method to change the properties of an xronDTMLmethod <dtml-call expr="UserEvent_TEST.manage_changeProperties( title = 'Modified ' + ZopeTime().strftime('%Y%m%d - %H:%M'), executeAt = timestr, periodDays = 1.0, data = 'Test' )"> running this changes the title property of the parent folder of the UserEvent_TEST method (xron method). Anyone? Thanks Alan Capesius, MCSE/NTCIP+20 http://twsite.bizland.com/techtips.htm

I want it to be false in the case > of acquisition. Most of the time (in all practical cases), if hasattr(folder.aq_explicit, 'index_html'): will work. When you search the mailing list archives for a post "Unexpected acqusition behaviour", you will see some cases, where it will not work. A safe solution is to use "aq_base" (instead of "aq_explicit"). "aq_base", however, is only be allowed in External Methods... Dieter
