Unregistered Cracker function message

HFCDev

Hi all, 

  Occasionally, when I pass a strinified object to be converted back into its oscript object (in my case, a list), I get the following message.

Unregistered cracker function: s

Afterwards, the object is undefined (as one would expect if the string could not be converted).

Here is a sample string I'm trying to convert:

'{\'Product defect\',\'Wrong item\',\'Product doesn\'t suit needs\',\'Customer changed their mind\'}'

 

I believe the problem has to do with the apostrophe (which is escaped or at least it was).  Can anyone tell me what the rules are to properly escape a string going into Str.StringToValue() to avoid this message?

Not sure how you are getting that string but it was not created via StringToValueJ  The reason I know this is if I take the following:

 

String s

List l = {"Product defect","Wrong item","Product doesn't suit needs","Customer changed their mind"}

echo( l )

s = Str.ValueToString( l )

echo( s)

l = Str.StringToValue( s )

echo(l)

 

I get back the following result

 

{'Product defect','Wrong item','Product doesn\'t suit needs','Customer changed their mind'}

{'Product defect','Wrong item','Product doesn\'t suit needs','Customer changed their mind'}

{'Product defect','Wrong item','Product doesn\'t suit needs','Customer changed their mind'}

 

Which if I use that as an example

 

String s = "{'Product defect','Wrong item','Product doesn\'t suit needs','Customer changed their mind'}"

List l = Str.StringToValue( s )

echo( l )

 

Works perfectlyJ  So the example you provided while it looks like a serialized form it really isn’t.  As for the rules, I would use the api’s since they are reversible.  If coming from outside the server, then I would be looking at Web.fromJSON to deserialize from a string.
