Hi guys. Today we had something really strange with Pharo 2.0. We are serializing FLPackage: Object subclass: #FLPackage instanceVariableNames: 'extensionMethods behaviors mustInitialize preLoadActions postLoadActions additionalObjects' classVariableNames: 'MustInitializeByDefault' poolDictionaries: '' category: 'FuelPackageLoader' That definition, where 'extensionMethods' is before 'behaviors' it works perfect. However, when just switching the oder to: Object subclass: #FLPackage instanceVariableNames: 'behaviors extensionMethods mustInitialize preLoadActions postLoadActions additionalObjects' classVariableNames: 'MustInitializeByDefault' poolDictionaries: '' category: 'FuelPackageLoader' The serialization of PharoCore fails because a problem with a metaclass of HTTPSocket. Any idea what can happen? thanks -- Mariano http://marianopeck.wordpress.com
