[jbossseam-issues] [JBoss JIRA] Resolved: (JBSEAM-1252) SeamTest invokeMethod() breaks jboss-el: "Parameter types cannot be null"

SeamTest invokeMethod() breaks jboss-el: "Parameter types cannot be null" ------------------------------------------------------------------------- Key: JBSEAM-1252 URL: http://jira.jboss.com/jira/browse/JBSEAM-1252 Project: JBoss Seam Issue Type: Bug Components: Core Affects Versions: 1.2.1.GA Environment: Seam from CVS. Jboss 4.2.0CR2. Facelets and JSF RI Reporter: Stuart Robertson Assigned To: Pete Muir Priority: Minor Fix For: 1.3.0.BETA1 SeamTest and MockApplication pass null as parameters to the MethodBinding. Jboss-el throws if they are null, and expects a zero sized array. Here's an example of what breaks it: invokeMethod("#{register.register}"); Here's the exception thrown: FAILED: registerTest java.lang.NullPointerException: Parameter types cannot be null at org.jboss.el.ExpressionFactoryImpl.createMethodExpression(ExpressionFactoryImpl.java:53) at org.jboss.seam.util.UnifiedELMethodBinding.<init>(UnifiedELMethodBinding.java:18) at org.jboss.seam.mock.MockApplication.createMethodBinding(MockApplication.java:270) at org.jboss.seam.jsf.SeamApplication.createMethodBinding(SeamApplication.java:291) at org.jboss.seam.mock.SeamTest$Request.invokeMethod(SeamTest.java:400) at com.fb.core.test.catalog.RegisterAndLoginTest$RegisterFacesRequest.invokeApplication(RegisterAndLoginTest.java:254) at org.jboss.seam.mock.SeamTest$Request.run(SeamTest.java:488) at com.fb.core.test.catalog.RegisterAndLoginTest.registerTest(RegisterAndLoginTest.java:55) Here's a patch that made the test run successfully: ### Eclipse Workspace Patch 1.0 #P jboss-seam Index: src/main/org/jboss/seam/mock/SeamTest.java =================================================================== RCS file: /cvsroot/jboss/jboss-seam/src/main/org/jboss/seam/mock/SeamTest.java,v retrieving revision 1.66 diff -u -r1.66 SeamTest.java --- src/main/org/jboss/seam/mock/SeamTest.java 24 Apr 2007 02:32:58 -0000 1.66 +++ src/main/org/jboss/seam/mock/SeamTest.java 26 Apr 2007 12:16:10 -0000 @@ -397,7 +397,7 @@ */ protected Object invokeMethod(String methodExpression) { - return application.createMethodBinding(methodExpression, null).invoke(facesContext, null); + return application.createMethodBinding(methodExpression, new Class [0]).invoke(facesContext, null); } /** Though SeamTest would still not accept method expression parameters with this change.
