jens, thanks for your reply. It helped me a lot. Do you have me a tip how I can get all Z SQL Methods in an selection field. I've found the superValues('Z SQL Method') function, but I'm having problems using it, because it can only be used in python. So how can I get the result returned from this function in my dtml form? thanx in advance florian On Sun, May 13, 2001 at 09:57:42AM -0400, Jens Vagelpohl wrote:
florian,
without even looking at the code, when you use simple data types (lists, dictionaries, etc) to store your data you have to make sure that the persistence machinery gets tickled the right way whenever you update values. with those simple storage datatypes it won't know things have changed unless you specifically tell it.
you would need to do either something like this::
self.my_storage_dictionary['newvalue'] = x self._p_changed = 1
or you could do it like this:
dictionary = self.my_storage_dictionary dictionary['newvalue'] = x self.my_storage_dictionary = dictionary
or you could simply use one of the helper classes that come with zope, like "PersistentMapping". it emulates a dictionary and makes sure the persistence machinery gets told about changes.

Hi folks,
I've started to program a pivot table.
Therefore I've created three classes:
ZPivotTable, Row and Cell.
The ZPivotTable class contains a set of Row classes, stored in a dictionary, as well as the Row classes contain a set of Cell classes stored in a dictionary.
Now I am debugging the product and can't find the reason why the table doesn't store the rows in its dictionary.
Could you please help me finding this bug.
The source is stored under the following address: http://www.zope.org/Members/freiser/ZPivotTable/ZPivotTable-0.0.tar.gz
Thanks
