Is there any reason why ZSQL methods which work fine within folders do not work within Zclasses ? Instead they seem to give authentication errors. eg. /Products /Myproduct /MyClass /Methods /index_html /dtml_method /sql_method The ZSQL method works correctly when I try "test" - which means that the DB connection and SQL are correct. The DTML method ('dtml_method') calls 'sql_method' and parses the output. However, if I create an instance of this product and then try to access dtml_method using http://Zope/Instance_of_Myproduct/dtml_method I get a "authentication failure" and a pop-up asks me to log in again; however, not even Zope superuser can log in ! Before, I had these very same methods in a folder : /Folder /dtml_method /sql_method and it worked perfectly. I've enabled *every* permission in the zclass to allow full access but still this authentication error. Has anybody else encountered this ? Apologies for yet another post/question but : a) I've looked/searched the archive and tried almost everything. b) After previous experience with zclass, I don't want to waste too much time if it's actually a problem with zclasses. So, any help greatly appreciated. cheers, chas ps. running zope 2.0 on NT
