    <p>I use <code>org.apache.commons.beanutils.MethodUtils</code> (<a href="http://commons.apache.org/beanutils/api/org/apache/commons/beanutils/MethodUtils.html" rel="nofollow">api link</a>) on occasion. I generally avoid reflection, but alas this case called for it. </p> <p>My problem comes to testing. I use Mockito for mocking, and when I call <code>MethodUtils.invokeMethod</code> with a mock as an argument, MethodUtils throws a <code>NoSuchMethodError</code> because it thinks the mocked object doesn't match the parameter type. Any suggestions?</p> <p>Signature of concrete method I'm calling:</p> <pre><code>public void propagateMirrorRateOfferId(MasterAvailabilityRule masterAvailabilityRule) </code></pre> <p>My mock generation:</p> <pre><code>@RunWith(MockitoJUnitRunner.class) public class SomeTest { private static final Long RATE_OFFER_ID = 1L; private static final Long RATE_ENTITY_ID = 2L; private static final Long ORIGINAL_RATE_OFFER_ID = 3L; private static final Long ORIGINAL_RATE_ENTITY_ID = 4L; @Mock MasterAvailabilityRule masterAvailabilityRule; PropertyAvailabilityRule propertyAvailabilityRule; @Before public void setUp() throws Exception { propertyAvailabilityRule = new PropertyAvailabilityRule(); propertyAvailabilityRule.setMirrorRateOfferId(ORIGINAL_RATE_OFFER_ID); propertyAvailabilityRule.setMirrorRateEntityId(ORIGINAL_RATE_ENTITY_ID); } @Test public void testPropagate() throws Exception { // arrange when(masterAvailabilityRule.determineAvailabilityMirroringRelationship(any(String.class))). thenReturn(new AvailabilityMirroringRelationship(RATE_OFFER_ID, RATE_ENTITY_ID)); when(masterAvailabilityRule.isMirrorLocked()). thenReturn(true); // action SomeUtility.thatCallsMethodUtilsAndPassesThisMock(masterAvailabilityRule); // assert assertEquals("Should have updated the mirrored rate offer id.", RATE_OFFER_ID, propertyAvailabilityRule.getMirrorRateOfferId()); assertEquals("Should have updated the mirrored rate entity id.", RATE_ENTITY_ID, propertyAvailabilityRule.getMirrorRateEntityId()); } } </code></pre> <h2>Thanks all, figured it out</h2> <p>In coming up with the examples for you guys, I put the MethodUtils call directly in my test and it worked. Turns out the I had imported the MethodUtils class from <code>org.apache.commons.lang.reflect.MethodUtils</code> in my utility class. For some reason, that version of the class fails with the mocks. When I use <code>org.apache.commons.beanutils.MethodUtils</code> it works. Not sure why. Perhaps I should update my original question to ask why the one in the <code>reflect</code> package fails... Anyway, will mark my question as answered once enough time has passed for me to submit an answer.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
