Regarding issue 12589. How should we do a file-out of a classTag from a Package? Nautilus and RPackageTag uses the RPackageTag name for display and file-outs. For example. RPackageTag "BasicObjects" in RPackage "Kernel" uses the name BasicObjects for the file-out file. The file is empty, because it uses SystemOrganization fileOutCategory: self name on: internalStream. I think it shoud use self categoryName instead of self name (Kernel-BasicObjects) What should we use for the file-out file name? self categoryName, too ? There is a problem with Packages like "AST-Core", as it includes a classTag with the same name. RPackage "AST-Core" and RPackageTag "AST-Core" should file-out to different files with different contents. Nicolai
