Hi esteban In Seaside, I created a subclass of WAFileLibrary then StefWAFileLibrary addAllFilesIn: 'foo' my folder foo contained a simple sh file I got a method created in the class side of StefWAFileLibrary I created a separated package and I could not save (I could save) but the method could be included. I added other methods by hand and they were saved but not the methods created by the addAllFilesIn: I suspect that the addAllFilesIn: did not raise a proper announcement. When I put a halt in snapshot packageSet does not get any methods. Stef snapshot | packageInfo definitions categories | self halt. packageInfo := self packageSet. definitions := OrderedCollection new. categories := (packageInfo packages collect: #packageName) asArray. categories isEmpty ifFalse: [ definitions add: (MCOrganizationDefinition categories: categories) ]. packageInfo methods do: [:ea | definitions add: ea asMCMethodDefinition] displayingProgress: [ :ea| 'Snapshotting methods...' ]. packageInfo overriddenMethods do: [:ea | definitions add: (packageInfo changeRecordForOverriddenMethod: ea) asMCMethodDefinition] displayingProgress: [ :ea| 'Searching for overrides in ', ea asString ]. packageInfo definedClasses do: [:ea | definitions addAll: ea classDefinitions] displayingProgress: [ :ea| 'Snapshotting class ', ea asString ].
