I am working on a large multiple object application product and in one module I have encountered an unauthorized context' error that I have been unable to solve over several days now. The following classes make up the module causing me problems. Most of the classes are pure Python and used outside of Zope as well. class KVItem: """ A (key, value) object that contains metadata about key and value and that when displayed as a string is key=value """ def getType(self): return self._type def getKey(self): return self._key def getVal(self): return self._val def getFlags(self): return self._flags class KVItems: """ A collection of KVItem objects """ def getKVItems(self): return self._items class URLBase: """ Basic URL class """ class Query: """ A URL Query Class """ def __init__(self, query=None, **qitems): if query is None: query = qitems self._query=KVItems(query) def getQueryItems(self): """ Returns a list of KVItem objects that make up the query """ return self._query.getKVItems() class URL(URLBase, Query): pass class Link(URL, LinkTracker): """ A Link object. Mostly pure Python, but contains some conditional Zope code """ class ZLink(SimpleItem, Link): """ Zope version of Link """ zlink = ZLink(id='test', title='Test Link', href='http://localhost:9080/path/to/file.ext?key1=val1&key2:list=["val2a","val2b"]&key3:int=3') Now in the editZLinkForm.pt on zlink, I want to get access to the query items and their meta data. <table> <tr tal:repeat="qi here/getQueryItems"> <td tal:content="qi/getType">Data Type</td> <td tal:content="qi/getKey">Query Key</td> <td tal:content="qi/getVal">Query Value</td> </tr> </table> so the output would be: <table> <tr> <td>string</td> <td>key1</td> <td>val1</td> </tr> <tr> <td>list</td> <td>key2</td> <td>['val2a', 'val2b']</td> </tr> <tr> <td>int</td> <td>key2</td> <td>val3</td> </tr> </table> Unfortunately, when I try this ZPT fragment, I get the following Error: Error Type: TALESError Error Value: AccessControl.unauthorized.Unauthorized on You are not allowed to access getType in this context in '', line 113, column 10 The methods of KVItem are inaccessable. However, I must be able to edit the metadata of the KVItem objects that make up the query of the Link URL so that link templates with dynamic query data can generated on the fly fron REQUEST and SESSION data. I have messed with AccessControl.ModuleSecurityInfo in various places to see if I could gain access to the KVItem data to no avail. At this point I am not sure what to do. I have studied the Security chapter of the ZDG as well as searched the Zope site over and over. Any help would be greatly appreciated. Regards, Jarrod Kinsley
