Deserializing JSON values with allowImplicitConversion

Use the allowImplicitConversion option to accept JSON values that require implicit type conversion during deserialization.

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 Implicit and explicit JSON conversion in json.Serializer and util.JSON.

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 )

For more details, go to json.Serializer.setOption.
