noSelectionLabel in jsf? - jsf

There are many situations when we want to tell the user to select an option from a selectOneMenu component. In Seam this is easily solved using noSelectionLabel.
<h:selectOneMenu value="#{seasonHome.id}">
<s:selectItems value="#{seasonListQuery.resultList}"
var="season"
label="xxxSeason #{season.startYear}"
noSelectionLabel="Select Season"
hideNoSelectionLabel="true" />
<s:convertEntity />
</h:selectOneMenu>
Can you please tell me if there is something similar in JSF 1.2?
I'm using icefaces with a list for selectItems like:
<ice:selectOneMenu
id="#{id}"
required="#{required}"
styleClass="#{styleClass} #{not required ? 'graNotRequired':''}"
style="width: #{width};font-size: #{fontSize};"
partialSubmit="#{partialSubmit}"
disabled="#{disabled}"
value="#{fieldOneDataHolder[fieldTwo]}">
<f:selectItems value="#{selectableItems}" />
<f:validator validatorId="#{validatorId}" />
</ice:selectOneMenu>
(please ignore parameters, this is a custom component I made).
I can introduce a new <f:selectItem itemLabel="Please select" itemValue=""/> above f:selectItems but this is difficult (I have to find a way to hide it in some cases etc)...
Do you know other work-around?
Thanks.

<f:selectItem itemLabel="Please select" itemValue="" itemDisabled="true" rendered="#{isShown}" />
The itemDisabled will make it shown but not selectable.
The boolean in rendered will decide whether the item is shown or not.

how to display value data from bean to radio button jsf

Is it possible to display values from my bean to radio button in the view?
I'm using jsf.
<h:outputLabel value="Gender"/>
<h:selectOneRadio value="#{ctrlLogin.session.gender}" readonly="true">
<f:selectItem itemValue="Male" itemLabel="Male" itemDisabled="true" />
<f:selectItem itemValue="Female" itemLabel="Female" itemDisabled="true"/>
</h:selectOneRadio>
i already have a user bean that carries the actual value from the database
Of course it is possible. I assume that you have some kind of list in a bean? You really should provide some code. Anyway, the solution below should give you an idea how to populate radio buttons with values.
<h:selectOneRadio id="radio"
value="#{bean.selectedOption}">
<f:selectItems value="#{bean.listOfOptions}" var="item" itemLabel="#{item}" itemValue="#{item}" />
</h:selectOneRadio>

hideNoSelectionOption in selectOneMenu is not working as expected

I have the following selectOneMenu and within of my component I want to have an item which shouldn't be shown, for e.g. in cases where the value from #{Mybean.value} match a value from #{Mybean.ListValues} I don't want to have an empty option in my combo box .
<p:selectOneMenu value="#{Mybean.value}" hideNoSelectionOption="true"
required="true" requiredMessage="Required data">
<f:selectItem itemLabel="" itemValue="#{null}" noSelectionOption="true" />
<f:selectItems value="#{Mybean.ListValues}" var="option" itemLabel="#{option.optionName}"
itemValue="#{option.optionId}"/>
</p:selectOneMenu>
I searched, but I didn't find anything useful, just one link in primefaces forum where describes exactly this problem.
My primefaces version is 3.5
Edit: it is supported from version 9 and on, see the other answer.
That attribute doesn't exist in the official api or in the doc. Where did you get it from?
What you're actually looking for is the itemDisabled attribute on the f:selectItems component. It's this attribute that disables a selectItem from being selected. Historically, primefaces has had problems with that attribute.
Ideally, you should have
<p:selectOneMenu value="#{Mybean.value}" required="true" requiredMessage="Required data">
<f:selectItem itemLabel="" itemValue="#{null}" noSelectionOption="true" />
<f:selectItems itemDisabled="#{Mybean.value=='aValue'}" value="#{Mybean.ListValues}" var="option" itemLabel="#{option.optionName}" itemValue="#{option.optionId}"/>
</p:selectOneMenu>
hideNoSelectionOption implemented in PrimeFaces 9.0
Issue: https://github.com/primefaces/primefaces/issues/5886
PR: https://github.com/primefaces/primefaces/pull/5909
So, basically and based on #kolossus answer, we can in primefaces (when you are using <p:selectOneMenu...) case add the following empty item
<f:selectItem itemValue="#{null}" itemLabel="--select--" itemDisabled="#{Mybean.value ne null}" />
We can in primefaces (when we have to use
Note: In such case we don't need the following two tags:
hideNoSelectionOption="true"
and
noSelectionOption="true"

How to Freeze JSF Radio Buttons

i have the following jsf code:
<h:selectOneRadio value="#{ref.arrive.boardingInformation}">
<f:selectItems value="#{newMessage.boardingInformationSelectItemList}" />
</h:selectOneRadio>
Is it possible to freeze this kind of selectradiobutton in that way, that my user canĀ“t change the value?
This radiobuttons are only for reading and not for writing or changing.
Try this:
<h:selectOneRadio value="#{ref.arrive.boardingInformation}" disabled="true">
<f:selectItems value="#{newMessage.boardingInformationSelectItemList}" />
</h:selectOneRadio>

<p:selectOneMenu> getting null on submit/next

I am using primefaces wizard. During wizard flow all parameters saved correctly . However <p:selectOneMenu> items getting NULL on submit.Also on 'back', it will not show what I have selected. Same for <p:selectManyMenu> also. Any solution ?
Here is the code snippets.I'm using primefaces-3.0.M3 and jsf2.
<h:outputText value="Employee Status" />
<p:selectOneMenu id="employeeStatus"value="#{employeeRepositoryImpl.employeeStatus.title}">
<f:selectItem itemLabel="Select One" itemValue="" />
<f:selectItem itemLabel="Permanent" itemValue="Permanent" />
<f:selectItem itemLabel="Contract" itemValue="Contract" />
<f:selectItem itemLabel="Part-Time" itemValue="Part-Time" />
<f:selectItem itemLabel="Training" itemValue="Training" />
</p:selectOneMenu>
<p:message id="employeeStatusId" for="employeeStatus" />
This is in a <p:wizard> tab, while clicking next button or submit button, the itemValues getting null.Sorry for the re-post.
Have you deleted the previous post?
Anyway, firstly, you should upgrade to Primefaces 3.0.M4!
Secondly, it would be better to use a list along with f:selectItems and all those String values to be stored in a list(this way you have more control over what's in the list and what should the list return), but if you want to stick with f:selectItem try using it with the enclosing tag (it may be a bug without it):
<f:selectItem itemLabel="Permanent" itemValue="Permanent" ></f:selectItem>
Also, I repeat myself, upgrade to Primefaces 3.0.M4!
I have solved it by using primefaces AJAX
<p:ajax update="employeeStatus" listener="#{employeeRepositoryImpl.employeeStatusAjax}" />
inside my </p:selectOneMenu> and I check/process this in side employeeStatusAjax().

How to use h:selectOneMenu in f:selectItem?

<h:selectOneRadio id="profiles" layout="pageDirection" value="#{bean.selectedProfile}" style="font-size:12px;">
<f:selectItem itemValue="0" itemLabel="#{messages.msg_profile1} ">
<h:selectOneMenu id="countries" value="#{bean.selectedCountry}" required="false" style="width:190px">
<f:selectItems value="#{bean.countries}" />
</h:selectOneMenu>
</f:selectItem>
<f:selectItems value="#{fraudBinPageBean.profiles}"/>
</h:selectOneRadio>
I have written above code in my app. It is working fine.
But select box displaying above the radio button.
My requirement display the select box beside the radio button.
Can you please help me what is the problem?
Are you sure that it is working correctly? Referring to this answer it is not possible since the body of the f:selectItem tag must be empty.
Try to redesign your form that you get along without the nested h:selectOneMenu.
You want to keep your radio button and Select box in same line. This is more related to CSS.
Try This code.
<h:selectOneRadio id="profiles" layout="pageDirection"
value="#{bean.selectedProfile}" style="font-size:12px;display:inline">
<f:selectItems value="#{fraudBinPageBean.profiles}"/>
</h:selectOneRadio>
<f:selectItem itemValue="0" itemLabel="#{messages.msg_profile1} ">
<h:selectOneMenu id="countries" value="#{bean.selectedCountry}" required="false" style="width:190px">
<f:selectItems value="#{bean.countries}" />
</h:selectOneMenu>
as shown in above code Add CSS property Display:inline to your style attribute of selectoneradio
