Object does not support this operation
by WrestGalen＠aol.com 22 May '01

22 May '01

Hello everyone. I have a web page with a member base. When people wish to become "New" members, they mearly fill out the join form, and click ok. This goes into a folder called member_lists/profiles/ and clones a dtml-document called blank_sheet, and then modifies the properties of this clone to match the new information inputted by the user. However, when I submit the join (this had worked previously, but once we had updated the join form, it ceased working. On our other test page as well, which is strange since we didn't update that.) it gives me a "Object blank_sheet does not support this operation" error. The join form submits its data to submit_join, which does all the work. Here is the code for submit_join.  <dtml-with "PARENTS[-1].f_member_lists.profiles"> <dtml-with "manage_clone(blank_sheet,'new_' + REQUEST['character_name'],REQUEST)"> <dtml-call "manage_changeProperties( title=REQUEST['character_name'], age=REQUEST['age'], gender=REQUEST['gender'], politics=REQUEST['politics'], real_name=REQUEST['real_name'], character_name=REQUEST['character_name'], location=REQUEST['location'], race=REQUEST['race'], character_class=REQUEST['character_class'], specialization=REQUEST['specialization'], discipline_1=REQUEST['discipline_1'], discipline_2=REQUEST['discipline_2'], discipline_3=REQUEST['discipline_3'], char_description=REQUEST['char_description'], icq=REQUEST['icq'], aim=REQUEST['aim'], email=REQUEST['email'], days_active=REQUEST['days_active'], hours_on=REQUEST['hours_on'], currently_play=REQUEST['currently_play'], game_genres=REQUEST['game_genres'], used_play=REQUEST['used_play'], reasons=REQUEST['reasons'], where_hear=REQUEST['where_hear'], goals=REQUEST['goals'], contribute=REQUEST['contribute'], leadership=REQUEST['leadership'], drink=REQUEST['drink'], aliens=REQUEST['aliens'], animals=REQUEST['animals'], website=REQUEST['website'], )"> </dtml-with> </dtml-with> Thank you for filling out our application!

I also have a java script running for the fourm, which checks to make sure all the fields are filled in, but that is on join_form, not submit_join, so I don't think that's it (don't see why it would be either). Any help would be greatly appreciated. Thank you.

[BUG] in manage_exportObject in OFS/ObjectManager.py
by Jerome Alet 22 May '01

22 May '01

Hi, there's probably a bug in manage_exportObject: this method accepts a RESPONSE argument which default value is None, but at lines 515-517 there are the following lines: RESPONSE.setHeader('Content-type','application/data') RESPONSE.setHeader('Content-Disposition', 'inline;filename=%s.%s' % (id, suffix)) These lines are executed when the user choose to download the file from the export object form in the ZMI, so in this case RESPONSE is set correctly and there's no problem. However, when calling manage_exportObject programmatically without sending a valid RESPONSE argument these two lines raise an exception because RESPONSE is None: Error Type: AttributeError Error Value: 'None' object has no attribute 'setHeader' To see this error occur, just create a Python Script which contain the following line: context.manage_exportObject(id='Control_Panel', download=1) Click on the 'Test' tab, that's it ! Put in the Collector, issue number is 2241. hoping this helps. bye, Jerome Alet

activeimages and opera 5.11
by dave＠kovach.com 22 May '01

22 May '01

Hi - Has anyone experimented with getting the ActiveImages product to work with the Opera web broswer? Or run into any other compatibility issues with the javascript AI uses in other browsers? There seems to be a hang-up in the actual ChangeImage function: function AI_changeImages() { if (document.images) { for (var i=0;i <AI_changeImages.arguments.length; i+=2) { document[AI_changeImages.arguments[i]].src = eval(AI_changeImages.arguments[i+1] + ".src"); } } } This seems to work (partially tested): function changeImages() { if (document.images) { for (var i=0; i<changeImages.arguments.length; i+=2) { document[changeImages.arguments[i]].src = changeImages.arguments[i+1]; } } } Thanks David Kovach dave(a)kovach.com

Zserver stability problems
by nuno 22 May '01

22 May '01

Hello, I'm running zope 2.3.0 (Red -Hat Linux) behind apache with mod_proxy (ProxyPass) and fastcgi . All requests are satisfied successfully by Zserver , however it seems that sometimes the zope listener has to be restarted , which is not good ! What I have observed in particular, was that both apache an zope are up and working fine! But suddenly, all the requests made through browser to the zope web site, become in a blank page, the browser takes a long time to load and it shows up the not found web page. What seems to me so strange is, when this happen, both listeners are up ( netstat -l ). Then I do a restart to the zope listener and all becomes fine again ! During last week this happened four times ! I have read the zope.org mailing list and saw that other persons have problems with Zope Server, but I haven't found any suitable solutions to this problem of Zserver stability. Do you guys have any hints about the reasons of this behaviour? What should it cause this unexpected problem ? Thank you all Best regards Nuno

ARGH !! SQLSession!
by Paul Zwarts 22 May '01

22 May '01

Help me PLEAAASE! I am using the SQLsession product to use environment settings that are invisible to the user and sensitive to the session. Every so often without fail I get a KeyError about a session parameter. It DOES EXIST! Im not sure what to do to look into it. I've used SQLSession reliably in the past and Im confused where to look for the fault. I have a feeling that the PoPy201 adapter isnt working properly (I get hangs several times a day needing a restart), but I dont see how this would affect SQLsession at work. Is it possible that a hung thread in PoPy is dissallowing SQLSession from doing its SELECT statement causing it to return an error? Paz

RE: [Zope] Vote for Windowing Toolkit to use for Fat Client
by sean.upton＠uniontrib.com 22 May '01

Yuck. Sorry, but for x-platform development, if the Trolls are going to charge for Windows dev. license, it makes no sense to use this as a basis for an x-platform open-source project; this is not just KDE, it has to run on other platforms and still have a free core!!! This would have to run on Win32, and by using a commercial toolkit like Qt, you significantly raise the barrier to entry for potential developers. wxPython is (from the looks of it) going to be the defacto replacement for tkinter, and it is relatively friendly - and I believe wider used - and there is not reason to complain about using gtk widgets on *NIX, because the development is abstracted by a class library (and gtk widgets are much more aesthetically pleasing!). There is a practical (not dogmatic) reason to keep things free: you want to encourage widespread development and contribution, and you won't get that with a limit imposed by a commercial toolkit. What I don't understand is what differentiates most of the frameworks for desktop development (wxWindows, Qt, MFC, OWL, inti, etc), they all try to share the same idea space - but wxWindows at least qualifies as mature, modern, and free.
