This is not the same functionality as is provided by the "optional" attribute. How would I use it with an integer, for example? I don't want a default value; I want the option of not having the value set at all.
I like the optional attribute. I'd like to see it do more than sit idle in the code.
You don't have to do the typechecking in the 'arguments' box if you don't want. eg. in your arguments section: course="" subject="" And your method: select * from enrolments <dtml-sqlgroup where> <dtml-sqltest course type=int optional> <dtml-sqltest subject type=nb optional> </dtml-sqlgroup> The definition of the 'optional' tag from the docs might help here: '''A flag indicating if the test is optional. If the test is optional and no value is provided for a variable, or the value provided is an invalid empty string, then no text is inserted''' Hmm... looking at this definition, it seems you have found a bug (but setting the default value to "" in the arguments section will provide a workaround). Or maybe 'no value provided' means 'is None'. Anyone from DC want to provide a ruling? :-) -- Stuart Bishop Work: zen@cs.rmit.edu.au Senior Systems Alchemist Play: zen@shangri-la.dropbear.id.au Computer Science, RMIT University
