PropertyNotFoundException when the property is a JDK8 defender method --------------------------------------------------------------------- Key: JBEE-159 URL: https://issues.jboss.org/browse/JBEE-159 Project: JBoss JavaEE Spec APIs Issue Type: Enhancement Components: jboss-el-api Affects Versions: jboss-el-api_3.0_spec-1.0.2.Final Reporter: Rich DiCroce Assignee: Scott Marlow Priority: Minor Labels: java8 I have a class that implements an interface that uses Java 8's new defender methods feature. Some getters on the interface have default implementations, and the concrete classes don't override them. If I try to refer to one of these getters as a property like so: {code:xml} value="#{cc.filter.filter.valueChoices}" {code} Then I get this exception: {noformat} Caused by: javax.el.PropertyNotFoundException: The class 'com.lapis.jsf.framework.dao.search.DefaultEntityFilter' does not have the property 'valueChoices'. at javax.el.BeanELResolver.getBeanProperty(BeanELResolver.java:731) [jboss-el-api_3.0_spec-1.0.3.Final.jar:1.0.3.Final] at javax.el.BeanELResolver.getValue(BeanELResolver.java:351) [jboss-el-api_3.0_spec-1.0.3.Final.jar:1.0.3.Final] at com.sun.faces.el.DemuxCompositeELResolver._getValue(DemuxCompositeELResolver.java:176) [jsf-impl-2.2.6-jbossorg-4.jar:] at com.sun.faces.el.DemuxCompositeELResolver.getValue(DemuxCompositeELResolver.java:203) [jsf-impl-2.2.6-jbossorg-4.jar:] at com.sun.el.parser.AstValue.getValue(AstValue.java:140) [javax.el-3.0.0.jar:] at com.sun.el.parser.AstValue.getValue(AstValue.java:204) [javax.el-3.0.0.jar:] at com.sun.el.parser.AstEmpty.getValue(AstEmpty.java:66) [javax.el-3.0.0.jar:] at com.sun.el.ValueExpressionImpl.getValue(ValueExpressionImpl.java:226) [javax.el-3.0.0.jar:] at org.jboss.weld.el.WeldValueExpression.getValue(WeldValueExpression.java:50) [weld-core-impl-2.1.2.Final.jar:2014-01-09 09:23] at org.jboss.weld.el.WeldValueExpression.getValue(WeldValueExpression.java:50) [weld-core-impl-2.1.2.Final.jar:2014-01-09 09:23] at com.sun.faces.facelets.el.ContextualCompositeValueExpression.getValue(ContextualCompositeValueExpression.java:158) [jsf-impl-2.2.6-jbossorg-4.jar:] at com.sun.faces.facelets.el.TagValueExpression.getValue(TagValueExpression.java:109) [jsf-impl-2.2.6-jbossorg-4.jar:] ... 68 more {noformat} Two workarounds exist. One: you can override the default method in a concrete class and have it just call the default super method. Two: you can call the getter using a method expression instead of a value expression.
