Hello, I am using a session object to store a query string. The query string is used for a reload of the same query with two parameters changing their value when the user reorders a table column. This works fine under Zope 2.9.3 in Mozilla. The page on which this query string is stored en taken up again is in an iframe. The iframe html resides on a Zope server, the parents website's computer is a different one, but in the same domain. Now under Firefox the session object still can be referenced, but in Internet Explorer the page in the iframe does not reference the session object properly. It once records it and then adds the changing parameters to it,doubling them and making the SQL query run into an error. The url is: http://www.volkstellingen.nl/nl/gemeenten/ where after a search you can reorder table columns by clicking on the headers. The problem does not occur in IE when the page is used on its own, only when it is used in an iframe. The question then is: can it be that IE restricts the session behaviour in this situation? How can I solve it? Here is the code in a PythonScript, that is called in the search results html page. directionDict = {'gemeente':'gm_direction','provincie':'prov_direction', 'begindatum':'bd_direction','einddatum':'ed_direction','amsterdamse_code':'ac_direction'} if request.SESSION.has_key('firstquery'): if request.has_key('sort'): #user sorts column without a new query if request.richting == 'ASC': value = directionDict[request.sort] request.set(value, 'DESC') #put all other columns on ASC for k,v in directionDict.items(): if k != request.sort: request.set(v, 'ASC') else: value = directionDict[request.sort] #put all columns on ASC for v in directionDict.itervalues(): request.set(v, 'ASC') else: #user does a new query, session object exists del request.SESSION['firstquery'] query = request.QUERY_STRING first = request.SESSION['firstquery']=query for v in directionDict.itervalues(): request.set(v, 'ASC') else: #first query query = request.QUERY_STRING first = request.SESSION['firstquery']=query for v in directionDict.itervalues(): request.set(v, 'ASC') -- Henk Laloli
