xotcl2: - fixed "... info defaults ..." and "... info instdefaults ..." emulation in XOTcl 2 - fixed error message - extended regression test - bumped revision of nsf/xotcl/nx to 2.0b6
- added functiality for "cget" to call parameter-methods (e.g. "... cget -class"). The method cget calls either "/slot/ get ..." (when slot=... is provided in the parameter spec) or it assumes that the method without argument returns the value - added "::nsf::object::property /obj/ volatile" to query whether a object is volatile or not - "/obj/ cget -volatile" returns now the volatial state of the object - factored out ParameterMethodDispatch() from OConfigureMethod() - extended regression test
