In my page i have a inputtextbox which is used
<h:inputText id="min" maxlength="5" value="#{beanName.minLength}"
binding="#{mininput}" >
<rf:validator event="blur" />
</h:inputText>
I am giving value like 12.12 i am getting below error message
contentform:equipFeatAdd:min: '12.12' must be a number between
-2147483648 and 2147483647 Example: 9346
I am not able to understand why it is showing message for float value its due to binding field in Integer ?
EDIT:-
Binding varaible is used in another InputText like this
<h:inputText id="max" maxlength="5" value="#{beanName.maxLength}"><f:validator validatorId=" portal.validators.NumberComparisonValidator" />
<f:attribute name="mininput" value="#{mininput}" />
<rf:validator event="blur" />
</h:inputText>

In a managed bean I have a property of the type int.
#ManagedBean
#SessionScoped
public class Nacharbeit implements Serializable {
private int number;
In the JSF page I try to validate this property for 6 digits numeric input only
<h:inputText id="number"
label="Auftragsnummer"
value="#{myController.nacharbeit.number}"
required="true">
<f:validateRegex pattern="(^[1-9]{6}$)" />
</h:inputText>
On runtime I get an exception:
javax.servlet.ServletException: java.lang.Integer cannot be cast to java.lang.String
java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String
Is the regex wrong? Or are the ValidateRegex only for Strings?
The <f:validateRegex> is intented to be used on String properties only. But you've there an int property for which JSF would already convert the submitted String value to Integer before validation. This explains the exception you're seeing.
But as you're already using an int property, you would already get a conversion error when you enter non-digits. The conversion error message is by the way configureable by converterMessage attribute. So you don't need to use regex at all.
As to the concrete functional requirement, you seem to want to validate the min/max length. For that you should be using <f:validateLength> instead. Use this in combination with the maxlength attribute so that the enduser won't be able to enter more than 6 characters anyway.
<h:inputText value="#{bean.number}" maxlength="6">
<f:validateLength minimum="6" maximum="6" />
</h:inputText>
You can configure the validation error message by the validatorMessage by the way. So, all with all it could look like this:
<h:inputText value="#{bean.number}" maxlength="6"
converterMessage="Please enter digits only."
validatorMessage="Please enter 6 digits.">
<f:validateLength minimum="6" maximum="6" />
</h:inputText>
You can achieve this without regex also
To validate int values:
<h:form id="user-form">
<h:outputLabel for="name">Provide Amount to Withdraw </h:outputLabel><br/>
<h:inputText id="age" value="#{user.amount}" validatorMessage="You can Withdraw only between $100 and $5000">
<f:validateLongRange minimum="100" maximum="5000" />
</h:inputText><br/>
<h:commandButton value="OK" action="response.xhtml"></h:commandButton>
</h:form>
To validate float values:
<h:form id="user-form">
<h:outputLabel for="amount">Enter Amount </h:outputLabel>
<h:inputText id="name-id" value="#{user.amount}" validatorMessage="Please enter amount between 1000.50 and 5000.99">
<f:validateDoubleRange minimum="1000.50" maximum="5000.99"/>
</h:inputText><br/><br/>
<h:commandButton value="Submit" action="response.xhtml"></h:commandButton>
</h:form>
I have 2 fields in a jsf form. Field 1 uses rich:autocomplete, and field 2 uses inputText. I type invalid data in field 2 so that the validation message appears. Next, I start typing in field 1. As soon as I do this, the validation message in field 2 disappears. How can I prevent this?
<h:outputLabel value="Field 1:" escape="false"/>
<h:panelGroup>
<rich:autocomplete id="id1" mode="ajax" showButton="false"
autocompleteMethod="#{bean.method}"
autocompleteList="#{bean.aList}"
value="#{bean.field}"
required="true"
requiredMessage="Field 1 required">
<a4j:ajax event="blur" execute="#this" bypassUpdates="#{true}" render="id1,id1Msg" />
</rich:autocomplete>
<rich:message for="id1" id="id1Msg" />
</h:panelGroup>
<h:outputLabel for="id2" value="Field 2:"/>
<h:panelGroup>
<h:inputText id="id2" value="#{bean.field2}" style="width: 175px;" required="true" requiredMessage="Field 2 required" validatorMessage="Field 2 Please enter digits only" converterMessage="Field 2 - Please enter digits only">
<f:ajax event="change" execute="#this" bypassUpdates="#{true}" render="id2Msg"/>
</h:inputText>
<rich:message for="id2" id="id2Msg"/>
</h:panelGroup>
Set execute="#form" on id2. This will cause id2 to always trigger the submission of the entire form, even when it loses focus, causing the validation message to appear
execute="#this" on id2 as it stands means that only the parent component will be triggered
I got the desired behaviour by using execute="#form" on id1.
I'm using primefaces with jsf and i want to make one of two fields required at least. that means that the error message will be displayed if this two fields are empties togheter:
this is a sample of my code:
<h:outputLabel for="srcNumber" value="Originator MSISDN (EXAMPLE 32495959595)" />
<p:inputText id="srcNumber" value="#{cdrMmscRecBean.srcNumber}" label="srcNumber" />
<h:outputLabel for="destNumber" value="Destination MSISDN (EXAMPLE 32495959595)" />
<p:inputText id="destNumber" value="#{cdrMmscRecBean.destNumber} label="destNumber" />
thanks :)
You can implement it this way:
<p:inputText id="srcNumber" value="#{cdrMmscRecBean.srcNumber}" label="srcNumber"
required="#{empty cdrMmscRecBean.destNumber}" requiredMessage="SRC Number Required">
<p:ajax event="change" update="destNumber" />
</p:inputText>
<p:inputText id="destNumber" value="#{cdrMmscRecBean.destNumber}" label="destNumber"
required="#{empty cdrMmscRecBean.srcNumber}" requiredMessage="DEST Number Required">
<p:ajax event="change" update="srcNumber" />
</p:inputText>
For more reference on how to parametrize your validation message:
Parametrized Messages in JSF with Facelets Taglib Functions
If you want to show the validation error use <p:message for="srcNumber" />
and same for test number, get rid of your outputLabels, this will show the validations warnings.
You neeed to add the required="true" flag to your inputTexts as well.
This is primefaces
EDIT
Purpose of the h:outputLabel and its "for" attribute this here shows the outputLabel for using non primefaces to show validatoin messages if this is all your problem was then u just need to add the required="true" validation flag indicators on your input texts
I have the following usage of the p:selectOneMenu:
<p:selectOneMenu id="selectField"
value="#{someBean.someField}"
converter="#{selectItemConverter}" var="x" editable="true">
<f:selectItems
value="#{selectItemsBean.getSelectItems(tab, field)}" var="si"
itemLabel="#{si.label}" itemValue="#{si}" />
<p:column>
<h:outputText value="#{si.label}" />
</p:column>
<p:column>
<h:graphicImage library="images" name="noway_16x16.png"
title="#{si.disabledReason}" rendered="#{si.disabled}" />
</p:column>
<p:ajax event="change" update="#form" partialSubmit="true" process="selectField" />
</p:selectOneMenu>
As you can see, I use custom content in combination with editable=true. When I submit the form, the Converter gets the label of a selected item as the value, not the actual value. In the HTML page, the values are correct, e.g. <option value="C">C-style mounting</option>. With editable=false, the correct value (e.g. C is sent to the converter, with editable=true the converter retrieves C-style mounting.
What I want is that the user can either select one of the pre-defined items in the list and the server submits that value of the item OR the user enters something and that is submitted as value. But the current behavior is a bit strange - or am I just wanting too much?
My requirement is like this: I am having a text input and whenever a value change event occurs, a select many list box has to be populated. If there is no matching records found, then a text input has to appear instead of a select many list box.
<h:column>
<h:selectManyListbox size="3" value="#{hostInfoBean.gateKeeperendPointReference}" rendered="#{hostInfoBean.selectManyRendered}" id="gateKeeperendPointReference">
<f:selectItems value="#{hostInfoBean.gateKeeperendPointReferenceItems}" />
</h:selectManyListbox>
<h:inputText id="gateKeeperendPointReferenceText" size="30" rendered="#{!hostInfoBean.selectManyRendered}">
</h:inputText>
</h:column>
Also I am using a4j for the value change listener,
<a4j:support event="onchange" reRender="hostInfo:gateKeeperendPointReference" focus="GFacPath"
ajaxSingle="true" />
'selectManyRendered' is a boolean value which I am determining in the JAVA bean. The program works only for the default value of the boolean variable. If the boolean value is changed during runtime, then the toggle between the visibility of selectManyListbox and inputText is not working. Please help to fix this. Am i missing something?

Suresh
If the "rendered" attribute resolves to false, then the component isn't in your tree and can't be found as a "rerender" target. When you have components that are rendered conditionally you want to wrap them in a component that is always available as a target, like so:
<h:inputText value="#{myBean.text}" >
<a4j:support event="onkeyup" reRender="listZone" ajaxSingle="true" />
</h:inputText>
<h:panelGroup id="listZone">
<h:selectManyListbox value="#{myBean.list}" rendered="#{myBean.renderList}" >
<f:selectItems value="#{myBean.listItems}" />
</h:selectManyListbox>
<h:inputText size="30" rendered="#{!myBean.renderList}/>
<h:panelGroup id="listZone">
