Hi Everyone, Attempting to file out changes from the Change Sorter results in an 'Improper store into indexable object'. (To reproduce this, right click on any change set and choose "File out"). I believe the root cause of the problem is: CodeExporter class>>writeSourceCodeFrom: aStream toFileReference: aFileReference aFileReference writeStreamDo: [ :outputStream | (ZnCrPortableWriteStream on: (ZnCharacterWriteStream on: outputStream encoding: 'utf8')) nextPutAll: aStream contents. ]. self inform: 'Filed out to: ', String cr, aFileReference basename ZnCrPortableWriteStream expects a binary stream and is being given a multi-byte file stream. The obvious solution is to add FileReference>>binaryWriteStreamDo: and associated methods. Can someone who is more familiar with the Zinc package confirm that my understanding is correct?
