RF4 CR1 - <rich:tabPanel> and activeItem... bug?

[pablo53]

Hi!

Has anyone tried to use activeItem attribute in <rich:tabPanel>? I always get the following exception, no matter what the tab panel content is:

java.lang.NullPointerException

Should I consider this a bug? Is there any workaround?

After getting rid of the attribute, exception is not thrown. This way, however, I cannot control active tab form the code behind. Does anybody know another way to control actve tabs?

Thanks in advance.

activeItem used at richfaces-showcase for navigation tabPanel and I do not saw such problems neither before CR1 nor after the relase. so need more details like page and bean.

[pablo53]

The XHTML fragment is as follows:

    <rich:tabPanel id="tpaneWnplatProject" switchType="ajax" activeItem="#{managedBean.projActiveTab}">

        <rich:tab id="wnplatProject1" header="1. #{msg['wnplat.project.title_tab1']}">

            <f:subview id="svwWnplatProject1">

                <ui:include src="project1.inc.xhtml" />

            </f:subview>

        </rich:tab>

        <rich:tab id="wnplatProject2" header="2. #{msg['wnplat.project.title_tab2']}">

            <f:subview id="svwWnplatProject2">

                <ui:include src="project2.inc.xhtml" />

            </f:subview>

        </rich:tab>

        <rich:tab id="wnplatProject3" header="3. #{msg['wnplat.project.title_tab3']}">

            <f:subview id="svwWnplatProject3">

                <ui:include src="project3.inc.xhtml" />

            </f:subview>

        </rich:tab>

    </rich:tabPanel>

"managedBean" is @SessionScoped, of course, and has projActiveTabs property with getter and setter included. The issue is reproducible also for explicitly setting activeItem="0".

[pablo53]

Ok, I found it!

activeItem must equal to one of the rich:tab's id... Mea culpa... I'm a newbie.

Regards,

[ahoehn]

hmm i have tried to set it to the tab-id, but the result was allways a nullpointerexception. Then I have changed it to the value of the name attribute of this tab. After that it was working... Just if others have the same issue

<rich:tabPanel switchType="ajax" id="contentTab" activeItem="myTabName2">

<rich:tab id="myTabId1" name="myTabName1" />

<rich:tab id="myTabId2" name="myTabName2" />

</rich:tabPanel>

Hi,

I have been facing this problem when I dynamically add the rich tabs.

ViewWageBean.java

private List<AggregateTypeBO> aggTypeCol = new ArrayList<AggregateTypeBO>();

if(StringUtils.equals(search.getJurisdictionCode(), "NC")){

                    return "payroll";

                }else{

                    aggTypeCol = wageService.getAggregationTypeInfo(search.getRequestId(), search.getReplyId());

                    setAggTypeCol(aggTypeCol);

I have the setter/getters for this property.

viewWage.xhtml

<rich:tabPanel id="tapPanel" activeItem="#{viewWageBean.currentTab}" switchType="ajax">

        <a4j:repeat value="#{viewWageBean.aggTypeCol}" var="cap">

                     <rich:tab name="#{cap.aggregateType}" actionListener="#{viewWageBean.selectTab}" id="#{cap.aggregateType}" >

                           <h:outputText value="fun" />

                     </rich:tab>

           </a4j:repeat>

</rich:tabPanel>

The bean is in Session Scope. I see this value #{viewWageBean.aggTypeCol} are available in setter/getters.

public void selectTab(ActionEvent event){

        setCurrentTab(event.getComponent().getId());

    }

Thru action listener I get the id of the tab and set it inactiveItem attribute but am facing the

  java.lang.IllegalArgumentException: Empty id attribute is not allowed

Business Exception:  An unknown error occurred.

Could you please help me how to resolve this problem???

[klhoste2]

Hi,

You should use c:forEach instead of a4j:repeat, that's what I did and it works, except for tab removal.

See explanation here: http://www.ninthavenue.com.au/blog/c:foreach-vs-ui:repeat-in-facelets

If you want to help to resolve my issue, see my post https://community.jboss.org/thread/195685

[jsf_pk]

Thanks Kevin...

I have tried your idea but that too failed in my case... after a prolong effort, I just hard coded the tab panel with rendered attribute. If the attribute value is true then the specific tab will be displayed.

<rich:tabPanel rendered="#{viewWageBean.isWeekly()}">

                <rich:tab name="Weekly" >

                    <h:outputText value="in the weekly tab"></h:outputText>

                    <ui:include src="/user/wage/weekly.xhtml"></ui:include>

                 </rich:tab>

</rich:tabPanel>

Finally this approach is quite easy to handle. Thanks Kevin and others.
