Hello, If I use Zope 2.6.1, I can install the "PluginIndexes" Product without any problems. But with Zope 2.5.1 I get the following error Message: Zope Error Zope has encountered an error while publishing this resource. Error Type: SystemError Error Value: Failed to import class _extra from module Products.PluginIndexes.TextIndex.Vocabulary How can I install PluginIndexes with Zope 2.5.1? Thank you Serkan ______________________________________________________________________________ UNICEF bittet um Spenden für die Kinder im Irak!

It seems to have been solved, so a very big thank you to: Oliver, Dylan, Chris, Dieter, Josef, and Tom (I don't think I missed anyone, if I did, sorry!!). Thank you all so very much for all of your time and effort. The suggestion from Oliver seems to have sorted it. By the way, .. >Look at the source of the page where you see that, if your browser >tries to interpret the return value as html, this will hide things like ><type 'bla'>. You were right, I can't believe I didn't even think of looking at the source (although the things I've managed not to think of over the last couple of days have been quite amazing - sorry everyone, I hope I'm not the only one who sometimes misses the obvious under duress!). Kind regards Ashley _________________________________________________________________ Worried what your kids see online?

Hello everybody, I have an idea of how to config ht://Dig Search Engine with Apache server, can somebody assist me on how to config this software with zope server runing on Linux RedHat.

wysiwyg and htmlarea
by Fearless Froggie 24 Apr '03

24 Apr '03

I noticed the other week somebody asked whether HTMLArea worked with Zope. Well, somebody is working on a zope adaptation of it: http://www.zope.org/Members/to_be/htmlarea. I haven't tried the original or the Zope version myself, but this is exactly what I'm looking for so I'm very excited! Hopefully I'll still be very excited once I've had a chance to try it out :) Rita. __________________________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier.

How to use CMF with own view methods? (was: Re: [Zope] Zope Lockup (ZPublisher stops responding?)
by Jaroslav Lukesh 23 Apr '03

23 Apr '03

Hi, I have another question, but I try suggest You another point of view to Zope locking. How about your operating system? Do you have linux 2.4.21 kernel or you have something different, or different platform? In case of BSD, here are known problem with locking, see mailning list archive. With Linux 2.4 kernels <=2.4.20 here are many general problems with slowdown and locking (as I was read at czech linux mailing list). Same Zope lockout I was find in Windows NT 2000. I was move to Linux (Mandrake 9.1 with 2.4.21 kernel) and I have no problem for 3 weeks, before in windows Zope locks each 2-3 days with no significant load. I use Zope without any frontend directly from port 80, only non-intelligent corporate firewall is before. Now I have my question - would you reccomend me how to use CMF or Plone with my own view method? My view method render whole content of given folder from index_html, if here are few documents, it renders it as page segments (STX or HTML) with possible image. But I am absolutelly new to CMF, I have installed it last week and no have time to play. Many thanks, J. Lukesh ---------- Odesílatel: Jean-Francois.Doyon(a)CCRS.NRCan.gc.ca happen during a day, since we use the CMF features only for internal authoring of your site. I'd think this "locking" issue would be a problem

Josef, Thanks very much for the email. I have tried as you suggested, changing the function definition to: def run(self, fileID='mydefaultID.pdf',lines=['Error','no lines passed in']): and calling it with: <dtml-let link="sping2(fileID=fileId,lines=mylines)"> But, again I seem to get the same (or a similar) error: ===================================================================== Error Type AttributeError Error Value __getitem__ Traceback (most recent call last): File "C:\PROGRA~1\ZopeSite\lib\python\DocumentTemplate\DT_Try.py", line 149, in render_try_except result = render_blocks(self.section, md) File "C:\PROGRA~1\ZopeSite\lib\python\DocumentTemplate\DT_Let.py", line 75, in render else: d[name]=expr(md) File "C:\PROGRA~1\ZopeSite\lib\python\DocumentTemplate\DT_Util.py", line 159, in eval return eval(code, d) File "", line 2, in f File "C:\PROGRA~1\ZopeSite\lib\python\Products\ExternalMethod\ExternalMethod.py", line 205, in __call__ return apply(f,(self.aq_parent.this(),)+args,kw) File "C:\PROGRA~1\ZopeSite\Extensions\formatted-strings.py", line 29, in run for line in lines: AttributeError: __getitem__ ===================================================================== Again, if I just return lines, or fileID, before this loop, it returns the value fine. Thanks again for your help.

You could write them to a file, or return them to zope, something like this - def test(lines): return `lines` In Zope, you can display the return value with <dtml-var "test(lines)"> (assuming of course that Zope knows what "lines" is, which you think you have handled already). If "lines" is truly a list of strings, the display will show that. If it is not, it is no wonder your code is not working right. Let us know the results. Cheers, Tom P

Local roles and acquisition
by Etienne Labuschagne 23 Apr '03

23 Apr '03

I have the following problem regarding local roles and acquisition: Folder structure: A------B------index_html | ----worker A and B are folders, worker is an object with some handy methods. These methods are declared protected with security.declareProtected('Manage properties'). The index_html in B uses some of the functions in worker, so whoever is using index_html must have a role that has the permission 'Manage properties'. When I assign a local role to someone in folder B that has the permission 'Manage properties', I still cannot access the protected methods in worker. Also, trying to do things like http://mysite/A/B/worker/someMethod or http://mysite/A/worker/B/someMethod doesn't work (I get the login box.) How does Zope resolve security when using acquisition to access methods. Proxy roles won't help as I am using a product and in this case, index_html is a skin method in a CMF site, so I can't assign a proxy role to index_html. Thanks Etienne.

Dividing Products into separate Folders
by volker.wend＠efgbsh.de 23 Apr '03

23 Apr '03

He folks, I have two folders for Products, one for stuff that comes with Zope and one for stuff that I add to the installation later on. It seems to work fine but I get the following error message in the logfile: ------ 2003-04-22T18:14:40 PROBLEM(100) OFS.Application Duplicate Product name After loading Product '__init__.py' from 'E:\\Zope\\Products', I skipped the one in 'E:\\ZopeSite\\lib\\python\\Products'. Any Explanations ? Can I ignore that one ? Thanks, Volker Wend

I checked the logs and then some HTML. We did tell the web designers (customer's choice of design agency) to reference all images with absolute url (well, always start with the slash, e.g "/images/navigation/home.gif", but they didn't (so they are: "images/navigation/home.gif"). And there are hardly any 304 codes in the log. Would in this case an Accelerated HTTP Cache Manager help? I am afraid I would need to skim through about 100 files and change the HTML otherwise.
