Description

On page 146 of V2.01 of the spec, it is stated that conversion from Date to String is supported. However, getString on Date type results in an IllegalArgumentException. Here is a code segment:

public void testShowErrorsInSimpleFormat() throws Exception

{ DataObject test_obj = DataFactory.INSTANCE.create(API_TEST_TYPE); Date current_date = new Date(System.currentTimeMillis()); // getString does not work on Date type test_obj.setDate("dateVal", current_date); String returned_string = test_obj.getString("dateVal"); //Gives IllegalArgumentException }

And here is the XSD:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:sdo="commonj.sdo"
xmlns:simple="http://www.example.com/api_test"

<xsd:element name="apiTestElem" type="simple:APITest"/>

<xsd:complexType mixed="true" name="APITest">

<xsd:sequence>

</xsd:sequence>
</xsd:complexType>

I originally thought that also getDate was not working on String, but this was an error in my test case. I had been setting the String value to be Date.toString(). Fuhwei correctly pointed out that the String format that would allow conversion is given on page 72 of the specification and is different than what is returned by Date.toString(). I have tested with the correct String format and found that getDate works, so clearly this is not an error. However, I wonder if it would be a good idea to aditionally support the String format that results from Date.toString().
