FLSerializer in Pharo 6.1

Hi everyone,

the FLSerializer in Pharo 6.1 doesn’t work. I tried the example from the class comment and I always get

FileException: cannot open file: example.FL.

Is that a known problem?

Probably that's because you don't have write permission in working directory.

Re: FLSerializer in Pharo 6.1

No, that cannot be the problem.
The following works without problems:

| working stream |
working := FileSystem disk workingDirectory.
stream := (working / 'foo.txt') writeStream.
stream nextPutAll: 'Hello World'.
stream close.

Hi Stephane,

I take a fresh Pharo 6.1 image, put it on my desktop (macOs 10.12.6), and then I take the example from the FLSerializer class comment:

| sourceArray loadedArray |
sourceArray := Array
with: 'a string'
with: Transcript
with: [ Transcript show: 'a string' ].
^ FLSerializer serialize: sourceArray toFileNamed: ‚example.FL'

Evaluating this results in the Exception.

Re: FLSerializer in Pharo 6.1

I'm using flserialiser in Pharo Lambda on 64 bit, and it's working writing a context to an s3 bucket which is pretty hardcore, so I'd say it is working.

So there must be some difference you have found
