----------------------------------

             Summary: BeanUtils.setProperty set wrong newValue for a DynaBean with a Map Property
                 Key: BEANUTILS-485
                 URL: https://issues.apache.org/jira/browse/BEANUTILS-485
             Project: Commons BeanUtils
          Issue Type: Bug
          Components: Bean / Property Utils
    Affects Versions: 1.9.2, 1.9.1, 1.9.0
            Reporter: Mauricio


After 1.8.3 this stop to work and my legacy Struts 1.x application starting to have bugs... :(

Before was String.... now is String array ? Why ?

public class BeanUtilsTest {

	@Test
	public void testSetPropertyBeanUtils183_ok_butFailOn192() throws Exception {
		String[] value = { "odd" };

		DynaBean dynaForm = createForm();
		String propertyName = "mapProperty(one)";

		BeanUtils.setProperty(dynaForm, propertyName, value);

		@SuppressWarnings("unchecked")
		Map<String, Object> retrived = (Map<String, Object>) dynaForm
				.get("mapProperty");

		// on bean utils 1.7.0, 1.8.0 ... 1.8.3 is OK
		assertThat(retrived.get("one"), instanceOf(String.class));
		assertThat(retrived.get("one"), equalTo((Object) "odd"));

		// after 1.9.0 ... 1.9.2 is the problem...
		// assertThat(retrived.get("one"), instanceOf(String[].class));

	}

	private static DynaBean createForm() {
		DynaClass dynaClass = new BasicDynaClass("MyForm", null,
				new DynaProperty[] { new DynaProperty("mapProperty",
						java.util.HashMap.class) });

		try {
			DynaBean p = dynaClass.newInstance();
			// initialize
			p.set("mapProperty", new HashMap<>());
			return p;
		} catch (IllegalAccessException | InstantiationException ex) {
			throw new RuntimeException(ex);
		}

	}
