TomEE/MyFaces: EL exception NulPointerException for h:selectOneMenu
Leonardo,
Thanks for your response to my previous email where you proposed a fix
using MyFaces Commons (mcc taghandler).
Now, I'm wondering if this is TomEE or MyFaces. For some reason, filterYear
(Integer) seems to be NULL when enduser/myself click the following
commandButton.
<p:commandButton value="Browse" icon="ui-icon-search" immediate="true"
actionListener="#{pf_rollingStockController.prepareList()}"
ajax="false"/>
Please note the following:
1. web app is composed of CDI-managed-beans, running via TomEE 1.5.1 and
MyFaces 2.1.10, and JUEL 2.2.5
2. the xhtml and bean did not result in exception when I was running
Glassfish and JSF-managed-beans (at this time, last year, when this xhtml
and bean was in demand)
3. I had to check for NULL in 'getSelectOneFilterYear()' to fix this issue.
xhtml
<h:selectOneMenu value="#{pf_rollingStockController.filterYear}">
<f:selectItem itemValue="0"
itemLabel="#{pf_rollingStockController.selectOneFilterYear}" />
<f:selectItems value="#{pf_rollingStockController.allYears}"/>
<p:ajax partialSubmit="true"
listener="#{pf_rollingStockController.prepareList()}"
update=":pageContentPanel"/>
</h:selectOneMenu>
bean
import javax.inject.Named;
import javax.enterprise.context.SessionScoped;
@Named("pf_rollingStockController")
@SessionScoped
public class pf_RollingStockController implements Serializable {
private Integer filterYear;
@PostConstruct
protected void init() {
filterYear = 0;
}
public String getSelectOneFilterYear() {
/*** HAD TO ADD THIS TO FIX THE EXCEPTION BELOW ***/
if (filterYear == null) {
filterYear = 0;
}
/*** HAD TO ADD THIS TO FIX THE EXCEPTION BELOW ***/
if (filterYear == 0)
return "Select One";
else
return "Show All";
}

Re: TomEE/MyFaces: EL exception NulPointerException for h:selectOneMenu
Posted by Leonardo Uribe <lu...@gmail.com>.
Hi
If @PostConstruct, there is no error in MyFaces or Tomcat. I think the bug
is hidden in the application logic. Check the code related to p:ajax. If
a component is not executed (do the lifecycle over it) and is rendered,
the null could be added without notice. You need to be sure that all
the components involved in your logic are executed before render them.
regards,
Leonardo

Re: TomEE/MyFaces: EL exception NulPointerException for h:selectOneMenu
Posted by "Howard W. Smith, Jr." <sm...@gmail.com>.
Leonardo,
I just confirmed the following:
1. @PostConstruct, pf_RollingStockController.init() method is called
2. the h:selectOneMenu (below) is responsible, because the server log
(below) will show that the setter has null as an argument value
<h:selectOneMenu value="#{pf_rollingStockController.filterYear}">
<f:selectItem itemValue="0"
itemLabel="#{pf_rollingStockController.selectOneFilterYear}" />
<f:selectItems value="#{pf_rollingStockController.allYears}"/>
<p:ajax partialSubmit="true"
listener="#{pf_rollingStockController.prepareList()}"
update=":pageContentPanel"/>
</h:selectOneMenu>
Please note that the test steps do not include/involve clicking the
selectOneMenu, so the filterYear = 0 was not (or should not have been) set
to NULL by PrimeFaces' p:ajax component. So, is MyFaces or TomEE/openejb
responsible for h:selectOneMenu setting the value to NULL?

Re: TomEE/MyFaces: EL exception NulPointerException for h:selectOneMenu
Posted by "Howard W. Smith, Jr." <sm...@gmail.com>.
Leonardo,
I just confirmed the following:
1. @PostConstruct, pf_RollingStockController.init() method is called
2. the h:selectOneMenu (below) is responsible, because the server log
(below) will show that the setter has null as an argument value
<h:selectOneMenu value="#{pf_rollingStockController.filterYear}">
<f:selectItem itemValue="0"
itemLabel="#{pf_rollingStockController.selectOneFilterYear}" />
<f:selectItems value="#{pf_rollingStockController.allYears}"/>
<p:ajax partialSubmit="true"
listener="#{pf_rollingStockController.prepareList()}"
update=":pageContentPanel"/>
</h:selectOneMenu>
Please note that the test steps do not include/involve clicking the
selectOneMenu, so the filterYear = 0 was not (or should not have been) set
to NULL by PrimeFaces' p:ajax component. So, is MyFaces or TomEE/openejb
responsible for h:selectOneMenu setting the value to NULL?

Re: TomEE/MyFaces: EL exception NulPointerException for h:selectOneMenu
Posted by Leonardo Uribe <lu...@gmail.com>.
Hi
In my opinion, the stack traces shows that @PostConstruct is not
called or filterYear is set to null in some other place.
If the container is not calling @PostConstruct, TomEE is the one to
blame, but first I would check that assumption, using a debugger
or with a System.out.println().

Leonardo Uribe
