This looks funny.
Your "manage_changeProperties" calls a DMTL object.
This looks like a nameclash. I guess you have overridden some method of "PropertyManager" with a DML object.
Check line 320 in "OFS/PropertyManager.py" what method is called there and why it is a DTML object.
Dieter, thanks for the lead, but it is all very strange and I really don't understand what is happening... External Method: # threadFolder is a BTreeFolder2; viewCount is a property field on the BTreeFolder2 line 3227: threadFolder = self.unrestrictedTraverse(topFolder + forumId + '/' + threadId) line 3228: threadFolder.manage_changeProperties({'viewCount': threadFolder.viewCount+1}) OFS/PropertyManager.py line 299: def manage_changeProperties(self, REQUEST=None, **kw): ... line 317: if REQUEST: line 318: message="Saved changes." line 319: return self.manage_propertiesForm(self,REQUEST, line 320: manage_tabs_message=message) The call to manage_changeProperties in the External Method does not contain REQUEST, therefore line 320 in PropertyManger.py should never get executed, but it is part of the error traceback (copy below). This error goes away if I change the 'Access contents information' security setting from 'Manager' to 'Anonymous'. At this point I am rewriting the application to move the counts (and other update-intensive fields) from the property fields of the BTreeFolder2 and put them into a MySQL db. I expect that this will eliminate the error, but if anyone has any ideas as to what caused the error I would love to know! (i hate unresolved issues). Thanks again for the assistance. Jonathan
