rendered="#{beneficiaryController.show =='true'}"
value="#{beneficiaryController.beneficiary.email}" />
<p:selectOneMenu id="option"
value="{beneficiaryController.beneficiary.beneficiaryType}">
<p:ajax listener="#{beneficiaryController.handleChange}" update="email" immediate="true"/>
<f:selectItem itemLabel="#{commonMessages.selectItemLabel}" itemValue=""/>
<f:selectItems value="#{beneficiaryController.beneficiaryTypes}"
var="type"
itemValue="#{type}"
itemLabel="#{type.typeDescription}"/>

I have a p:selectOneMenu and in that list of values where the first value is "Select One" and other values are actual values fetching from db.
When the user selects other values then a dialog box is displaying and fetching respective values, however, after that if user select "Select One" then also displaying the dialog box. Here, I don't want to display dialog box when user select "Select One" from the dropdown.
Xhtml Code:
<p:selectOneMenu id="drp_modify"
value="#{BackingBean.Name}" panelStyle="width:180px"
effect="fade" style="width:180px" filter="true"
filterMatchMode="startsWith" onchange="PF('dlg_modify').show();"
title="Add">
<p:ajax listener="#{BackingBean.onNameChange}"
update="Name_ID, address" />
<f:selectItem itemLabel="Select One" itemValue="" noSelectionOption="true" />
<f:selectItems value="#{BackingBean.nameItemList}" />
</p:selectOneMenu>
<p:dialog header="Modify" widgetVar="dlg_modify" resizable="false">
//// some code
</p:dialog>
You can use JavaScript to check the current value of the combobox.
Instead of onchange="PF('dlg_modify').show();" you can write:
onchange="if(document.getElementById('yourFormId:drp_modify_input').value != '') PF('dlg_modify').show();"
where yourFormId is the ID of your form and the condition is the value given as an itemValue parameter in f:selectItem. In your case it's ''.
The situation:
I want to display specific panelGrid(s) on the page based on drop-down selection. I am doing this by storing several boolean which get set to true/false based on which item is selected in the drop down. I use the onchange="submit()" to refresh/re-render the page.
The problem:
I have validation on many fields in the form, so if I select an item it does validation and will not display the form.
The question:
How do I get the selectOneMenu change to re-render only the set of controls on the page being impacted instead of the whole page and causing validation?
The code: (JSF 1.2)
<h:selectOneMenu id="list" value="#{sessionBean.myDecorator.selectedItem}"
onchange="submit()" immediate="true" required="true"
valueChangeListener="#{requestBean.listChanged}">
<f:selectItem itemValue="#{null}" itemLabel="--Select One--" noSelectionOption="true" />
<f:selectItems value="#{sessionBean.myDecorator.mapItems}" />
</h:selectOneMenu>
Field causing validation:
<h:inputTextarea id="lblRequiredField" cols="100" rows="3" required="true" immediate="true"
value="#{sessionBean.myDecorator.myDo.myField}">
<f:validateLength minimum="1" maximum="300" />
</h:inputTextarea>
I am new to JSF and i am stuck at one place. I have one dropdown list which contains two items.
Bank
Cash
Now, if I select bank the other dropdown should populate items related to bank and if I select cash, cash items should be shown in 2nd dropdown.
How to do it in JSF? Where I have to make changes?
Any help will be highly appreciated.Thanks
Well you can use primefaces to improve jsf development
<p:selectOneMenu id="cboCountries" value="#{beanCountries.ValueSelected}" effect="fade">
<f:selectItem itemLabel="Select Country" itemValue="-1" /> //a default value
<f:selectItems value="#{beanCountries.listOfCountries}" var="countries" itemLabel="#{countries.name}" itemValue="#{countries.id}"/>
<p:ajax event="change" update="cboCities" listener="beanCountries.listCities()"/> //notice "update" refresh an especific DOM Element of an especific ID
</p:selectOneMenu>
<p:selectOneMenu id="cboCities" value="#{beanCities.ValueSelected}" effect="fade">
<f:selectItem itemLabel="Select City" itemValue="-1" /> //a default value
<f:selectItems value="#{beanCities.listOfCities}" var="cities" itemLabel="#{cities.name}" itemValue="#{cities.id}"/> //this is when you want to put elements from DB or from an Array
</p:selectOneMenu>
" is a special mark from primefaces, the event = "change" will invoke the you select an element from the first "ComboBox" then the property update will refresh the second comboBox, and the property "listener" will do the logical action of what you want to do, in this case the method "listCities()" will fill "listOfCities" with values from DB o Arrays.
So in jsf without primefaces will be like this:
<h:form>
<h:selectOneMenu value="#{beanCountries.ValueSelected}">
<f:selectItem itemLabel="Select Country" itemValue="-1" /> //a default value
<f:selectItems value="#{beanCountries.listOfCountries}" var="countries" itemLabel="#{countries.name}" itemValue="#{countries.id}"/>
</h:selectOneMenu>
<h:selectOneMenu id="cboCities" value="#{beanCities.ValueSelected}">
<f:selectItem itemLabel="Select City" itemValue="-1" /> //a default value
<f:selectItems value="#{beanCities.listOfCities}" var="cities" itemLabel="#{cities.name}" itemValue="#{cities.id}"/> //this is when you want to put elements from DB or from an Array
</h:selectOneMenu>
<h:commandButton value="Submit" action="beanCountries.listCities()"/>
</h:form>
this way is with a button (in jsf) and the action property will execute a java Method and then refresh the page. also this could be made by "ValueChangeListener" property of the selectOneMenu component
Is there a way to render a component based on the current value the user has selected from a selectOneMenu component? My selectOneMenu component is populated with an enum consisting of two values, smoker and non-smoker. If the user has smoker selected I want to render a checkbox below it which lets the user check how many they smoke a day 10, 20, 30+, etc. I also want the opposite to work if they user has selected non-smoker i.e. the check boxes don't render/disappear.
Just check the dropdown menu's value in the rendered attribute of the target components and update their common parent by a <f:ajax>. Here's a kickoff example:
<h:selectOneMenu value="#{bean.item}">
<f:selectItem itemValue="one" />
<f:selectItem itemValue="two" />
<f:selectItem itemValue="three" />
<f:ajax render="results" />
</h:selectOneMenu>
<h:panelGroup id="results">
<h:panelGroup rendered="#{bean.item eq 'one'}">
You have selected "one".
</h:panelGroup>
<h:panelGroup rendered="#{bean.item eq 'two'}">
You have selected "two".
</h:panelGroup>
<h:panelGroup rendered="#{bean.item eq 'three'}">
You have selected "three".
</h:panelGroup>
</h:panelGroup>
If you'd like to perform some business logic based on the selected value, use <f:ajax listener>.
<f:ajax listener="#{bean.changeItem}" render="results" />
public void changeItem() {
someResult = someService.getByItem(item);
}

I am wondering is there a way i can add delete() in the select one menu, so that the user either can select one from the menu or delete the record right from there itself. So far i have normal select one menu, i have a method called "#{statusReport.deleteTieckt}" method. I just wondering how to add that to the below select one menu.
<ice:selectOneMenu value="#{statusReport.projectDetID}"
style="width: 350px;" partialSubmit="true"
onchange="this.form.submit()" immediate="true"
valueChangeListener="#{statusReport.retrieveReport}">
<f:ajax disabled="true"></f:ajax>
<f:selectItem itemLabel="Select One" itemValue="" />
<f:selectItems value="#{statusReport.listOfProjectDetail}"
var="projectBO"
itemLabel="#{projectBO.projectDtObj.pname} #{projectBO.startDate} - #{projectBO.endDate}"
itemValue="#{projectBO.pdetailId}" noSelectionValue="true" />
</ice:selectOneMenu>
