problem with FLMaterializer
Hi everyone, trying to migrate a Seaside application from Pharo4 to Pharo6 I get a problem with FLMaterializer. An expression like (FLMaterializer materializeFromFileNamed: aFileRefence) results in MessageNotUnderstood: FileReference>>convertToWithConverter: The same file can be materialized in Pharo4 without problems. Johannes
Johannes Just a suggestion: FLMaterializer class >>materializeFromFileNamed: requires as argument aFilename, not aFileRefence. Presumably this means the name as a string. This makes sense, because #convertToWithConverter: is the name of a method understood by strings. If your invocation of the materializer includes asFileReference, try again without that.

Peter Your suggestion is correct. I correct the expression to (FLMaterializer materializeFromFileNamed: aFileRefence fullName) Now I get another exception. KeyNotFound: key #'ositive8SmallIntegerClusterJ4Ã1âð+â( %?Â"< 9ª 6PM¾0d*ÃD ''x!Å 8' not found in SystemDictionary I think this is a compatibility problem between different Fuel versions.

Hi, If you use Fuel to serialize objects with Pharo 4, then you can only materialize them with a Fuel from Pharo 4. Other versions of Fuel will not be able to read them.

In the EnterprisePharo Book there is a chapter "Fuel Format Migration". There the format migration form Fuel version 1.7 to 1.9 is shown. I ask me if there is a similar possibility for the migration between Fuel in Pharo 4 and 6.
