With version 1.3.0 I've tried to extend the class to support a new option in using the following code:

xotcl::nonPosArgs proc in { allowedValues argName args} { if { [lsearch $allowedValues $args] == -1 } { error "Invalid value |$args| for option $argName (allowed values: [join $allowedValues {, }])" } }

example:

Class create A A proc y {{{-q:in {add remove}} add}} {} { puts $q } A y; # prints add A t -q bad; # throw an error A y -q remove; # prints remove

With version 1.3.1 this code doesn't work anymore and the error returned is:

::xotcl::nonPosArgs: unable to dispatch method 'in {add remove}'

How can I change the prototype to make it work again ?

Thanks, Giovanni. --------------------------------------------------------------------
