Subject Configuration attribute overriding fails for nullable?
Date Fri, 31 Aug 2001 12:16:35 GMT
Hi All,

Parameter overriding does not appear to be working when I try to override
the 'nullable' attribute of a Configuration parameter:


	<parameter name="password" type="string" nullable="no" />

	<constraint-set name="modify">

		<validate name="password" nullable="yes"/>



I've tested overriding the other attributes (min, max, max-len ...) and they
work fine but the example above fails when the "modify" constraint-set if
used to validate a null "password" parameter.

I've verified this behaviour by adding extra debug into

>From what I can see, the construction of Configuration variables is not part
of the Cocoon2 codebase but is in the Avalon framework package. I'll
download the source for Avalon and see if I can find the bug but can
somebody please SHOUT if I'm going on a wild goose chase?
