Hi I have modified ZDGChart to display multiple columns of data returned from a ZSQL query. However I have not been able to find a way to display a legend which describes what data each line on the graph represents. Can anyone tell me how to display a legend. Thanks Austin

As luck would have it, the file did not import into Products (File /usr/local/Zope/lib/python/OFS/CopySupport.py, line 406, in _verifyObjectPaste) It DID import into the root folder (I did this purely by accident!) I was then able to recreate the called-for classes and IT WORKED!! I haven't figured out HOW yet but I will. Thanks a lot for the help, and let me know if you need any fancy Python methods...

Intercepting NotFoundError with standard_error_message
by Philipp Auersperg 01 Dec '00

01 Dec '00

I need to intercept NotFoundErrors, but am banging my head against a problem Normally this can be done by changing the standard_error_message, but there I have some questions: considering a minimal standard_error_message: -------------------------------------------------- <dtml-var standard_html_header> Error! <dtml-var standard_html_footer> -------------------------------------------------- When I provoke an error by referencing a non-existent resource the message 'Error!' gets displayed, but there is also a traceback which I cannot suppress, it always gets displayed as a HTML comment ------------------------ and now my questions 0: How can I suppress this traceback totally, my main goal Even on zope.org whe NotFoundError returns such a hidden traceback :( 1: when I remove the standard_header and footer from my standard_error_message I would expect that just the word 'Error' gets displayed, But no way, then I get a detailed Zope Error message with a traceback. How can I archive that I just get the word 'Error!' or something similar as a result. I need that desperately because such an exception is unusable when calling methods via XMLRPC, there I need a simple clear error code and not a long traceback message. 2: what makes me most happy would be returning a single XMLRPC marshallable value by dtml-return: ---------------------------------------------------- <dtml-return someErrorExpression> ---------------------------------------------------- I already have such a standard_error_message but it just works for user-generated exception, but not for the #@%&§$ NotFoundError I cannot believe that it is not possible to do error handling of NotFoundErrors but I've not found any information on that. Thanks in advance phil

Hi, Just to try , by using import/export i ported the product to another windows 98 machine.I am able to open the whole folder in the ported machine. The problem is i am not able to add a new record there using the existing script.If write new script to add record to the same table it works . so why it this happens like this ?. Do we need to import any other files?.When i add a record using existing scripts it asks for username & password. when i type it , it doesn't take. Thanks, jacintha

Is it possible to build a folder zclass with user folder built in?
by Dirksen 01 Dec '00

01 Dec '00

I built a user folder with LoginManager, tested it on normal folder. Then I tried to build a folder zclass containing the tested LM user folder, hoping that, when I instantiate this zclass, I have a folder ready for customized authentication. I tried this on objectmanager baseclass and ofs:folder baseclass, neither worked the way I anticipated, just weird behaviors. It seems to me the user folder works inside the zclass folder (under the product tree) rather than in its instance. Any hint please?

Finding PARENTS in an external method.
by Max M 01 Dec '00

01 Dec '00

I have an external Method. How do I call PARENTS[-1] from it? in dtml it would be: <dtml-in "PARENTS[-1].objectValues('Folder')"> I have tried something like: self.PARENTS[-1].objectValues('Folder') I have also checked if PARENTS get passed to the method like: myMethod(self, PARENTS=None): To get a list of the root's Folder's, but no luck.
