Why does the JSF 'binding' attribute cause the Seam error "@In attribute requires non-null value"?
Issue
-
If the "binding" attribute is specified by a Richfaces/JSF component, it causes the following Seam error.
javax.servlet.ServletException: /common/carrierLookupModal.xhtml @63,101 binding="#{carrierSearchAction.carrierTable}": Error writing 'carrierTable' on type com.whatever.example.common.action.CarrierSearchAction_$$_javassist_17 at Caused by: org.jboss.seam.RequiredException: @In attribute requires non-null value: carrierSearchAction.entityManager at org.jboss.seam.Component.getValueToInject(Component.java:2178) at org.jboss.seam.Component.injectAttributes(Component.java:1601) at org.jboss.seam.Component.inject(Component.java:1419) at org.jboss.seam.core.BijectionInterceptor.aroundInvoke(BijectionInterceptor.java:45) at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:68) ... 47 more
When attempting to bind my Richfaces component to a Conversation scoped EJB3 I receive the following exception
javax.el.PropertyNotFoundException: /actions/someXhtmlPage.xhtml @144,60 binding="#{MyBean.htmlView}": Target Unreachable, identifier 'MyBean' resolved to null
