Chris Chen closed JIBX-114:
---------------------------
Resolution: Cannot Reproduce
I apologize, but this is not a bug. It is a bug in my testing code. I was
testing the string against an array (which used to be a string) that contains a
list of strings.
I have fixed this and the test case is now running successfully.

> I am getting different XML document when marshalling and unmarshalling the
> same class data, using only default generated codes and no custom codes. The
> unmarshalling is the one causing the problem.
> Here's my binding file. The problem occurs in the instructions collection
> located in the first "x" element mapping.

> Here's my testcase, with comments attached to the code:
> //this is the string that the marshalled document is compared to
> String xml = "<x xmlns='jabber:x:data'
> type='submit'><instructions>simple instructions</instructions></x>";
> StringReader reader = new StringReader(xml);
> DataXPacket packet = new DataXPacket();
> packet.addInstruction("simple instructions");
> //marshalls the object
> JiBXUtil.marshallObject(writer, packet);
> //the comparison passes with no problem, indicating that marshalling
> is bug-free
> compare(reader);
> reader.reset();
> // unmarshalls the reader string above
> packet = (DataXPacket) JiBXUtil.unmarshallObject(reader,
> DataXPacket.class);
> // this assertion below FAILS with the exception shown below
> assertEquals("simple instructions", packet.getInstructions());
> Here's the exception that I get when running the code:
> [junit] expected:<simple instructions> but was:<[simple instructions]>
> [junit] junit.framework.AssertionFailedError: expected:<simple
> instructions> but was:<[simple instructions]>
> [junit] at
> com.echomine.jabber.packet.DataXPacketTest.testInstructions(DataXPacketTest.java:133)
> It's interesting that the marshalling code is outputting expected xml, but
> the unmarshalling does not parse the data as expected.

> of schema?
