problem with FLMaterializer

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.

 

Hope this helps

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.

Your suggestion is correct. I correct the expression to

(FLMaterializer materializeFromFileNamed: aFileRefence fullName)

Now I get another exception.

KeyNotFound: key #'ositive8SmallIntegerClusterJ 4Ü 1‚ ð+ –( %? "< 9 ª 6P M ¾0 d *ÒD ''x ! Œ 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.
