Just one more question for today. (-: I'm trying to create some optional arguments in Zope 2.0.0b1 to a Z SQL method using the sqlgroup and sqltest tags. My query is select * from links <!--#sqlgroup where--> <!--#sqltest link_num type=int optional--> <!--#or--> <!--#sqltest parent type=int optional--> <!--#/sqlgroup--> and I've given it arguments of link_num:int parent:int There doesn't seem to be a way to make the arguments optional (or at least ignore empty values) as if I change and test this query, leaving one of the arguments empty, I get an 'Error response Error code 500. Message: Internal Server Error' from Zope, and the following error on the xterm which started up Zope 1999-08-06T07:21:50 ERROR(200) ZServer Server Error: exceptions.ValueError, Empty entry when <strong>integer</strong> expected: file: /scratch/zope/Zope-2.0.0b1-linux2-x86/lib/python/ZPublisher/Converters.py line: 124 It's pretty obvious that Zope thinks I should have supplied a value for another parameter, but I think the fact it causes an exception is a bug. I'm having great fun at the moment writing an interface to a HTML links database. All the links are stored in a MySQL table and Zope provides a super-nifty front end with a tree based navigation system. Zope is awesome! On another note, is there any chance of a searchable mailing list index being made for this list? I use google, but there seems to have been some reorganisation of the site since it was last indexed and all the pipermail links are broken. )-: Tim. -- Tim Potter, System Admin/Programmer "Disco Stu doesn't advertise" Advanced Computational Systems CRC, RSISE Bldg Australian National University, Canberra 0200, AUSTRALIA Ph: +61 2 62798813 Fax: +61 2 62798602
