1. ERROR #1: Using a bean that does not exists
In the previos entry we used this facelet file:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:p="http://primefaces.org/ui"> <h:head> </h:head> <h:body> <h:form> <h3> This file is for testing Primafaces using a Bean (TestComponentBean) </h3> <h2> In form/form-prova01.json a value property is set to a Bean-Property. and it is assigned programmatically in TestComponentBean </h2> <h:panelGroup binding="#{testComponentBean.pg}" /> <p:commandButton value="Submit"/> </h:form> </h:body> </html> |
If we create a new facelets file called testpage03-Problems.xhtml and change the red expresion for this one (using a bean that does not exist)
<h:panelGroup binding="#{nonExistingBean.pg}" />
We get a Target Unreachable error:
SEVERE: Servlet.service() for servlet [FacesServlet] in context with path [/JSFv01] threw exception [/pages/testpage03-Problems.xhtml @16,60 binding="#{nonExistingBean.pg}": Target Unreachable, identifier 'nonExistingBean' resolved to null] with root cause
javax.el.PropertyNotFoundException: Target Unreachable, identifier 'nonExistingBean' resolved to null
2. ERROR #2: Using a unexisting property from a bean
Now we change to
<h:panelGroup binding="#{testComponentBean.noExistingProperty}" />path [/JSFv01] threw exception [/pages/testpage03-Problems.xhtml@16,78 binding="#{testComponentBean.noExistingProperty}":Property 'noExistingProperty' not found on typeorg.ximodante.jsf.component.test.TestComponentBean] with root causejavax.el.PropertyNotFoundException: Property 'noExistingProperty'not found on type org.ximodante.jsf.component.test.TestComponentBean
