JSON to BDL deserialization option to allow implicit conversions

To relax deserialization, you can set the allowImplicitConversion option to allow implicit data conversion.

By default, Genero Web Services deserialization will raise errors if the JSON content does not match the BDL variable receiving the data. For more information on implicit and explicit conversion of JSON to Genero BDL, go to Understanding implicit/explicit serialization.

In this example, you have a BDL variable that is defined as follows:

PRIVATE TYPE TypedLists RECORD
    ints DYNAMIC ARRAY OF INT,
    strings DYNAMIC ARRAY OF STRING
END RECORD

The following JSON document will raise conversion errors by default because the "strings" array does not contain valid string values. For example, it should be formatted as "

strings":
["1", "2"]

" to correspond with the expected data type. Here is the original JSON:

{
    "ints": [1, 2],
    "strings": [1, 2]
}

To avoid the conversion error, you can set the following option in your server module to allow implicit type conversion:

CALL json.Serializer.setOption( "allowImplicitConversion", 1 )
