I am using PrimeFaces spinner, but while I give string values, it takes the string values to bean classes, but it should accept only numeric.
<h:outputLabel value=" Spinner: " />
<p:spinner value="#{bean.num}" />

I have the following JSF construct:
<c:set var="myVar" value="#{myBean.getMyMap()}" scope="request" />
<h:form>
<p>
<h:outputText value="Output1: " />
<h:selectOneMenu value="#{myMappingsBean.data.attribute1}" binding="#{input1}" required="true">
<f:selectItems var="entry" value="#{myVar}"/>
<p:ajax update="myDropdown"/>
</h:selectOneMenu>
</p>
<p>
<h:outputText value="Output2: " />
<h:selectOneMenu id="myDropdown" value="#{myMappingsBean.data.attribute2}" binding="#{input2}" required="true" converter="javax.faces.Double">
<f:selectItems var="entry" value="#{myVar.get(input1.value)}"/>
</h:selectOneMenu>
</p>
</h:form>
Behind myVar is a map defined like that: Map<String, Collection<Double>>
The first dropdown menu shows a list of all the keys of that map (like desired), but the value behind that is the collection of values.
Here the HTML output of one option of that dropdown:
<option value="[1.0, 2.0]">SomeString</option>
My second dropdown should list the collection of double values stored in the map behind the key, that is selected by the first menu.
The problem now is, when I use value="#{myVar.get(input1.value)}" the value I get from .value is the collection and not the string/key of the map. So I never get the desired result.
How can I get the string/key behind the binded object input1? Is there something like input1.name or .toString? Is somewhere a documentary for this?
Ok, I solved it by applying the solution from here.
The first drop down has to be edited to the following:
<p>
<h:outputText value="Output1: " />
<h:selectOneMenu value="#{myMappingsBean.data.attribute1}" binding="#{input1}" required="true">
<f:selectItems var="entry" value="#{myVar.entrySet()}" itemValue="#{entry.key}" itemLabel="#{entry.key}"/>
</h:selectOneMenu>
</p>
As you can see, the entry set is created from the map and from that you use the key as value and label.
And with that the value behind input1.value now is not the collection of doubles but the key of the map.
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 am using jsf number converter in my application as follows:
<p:inputText id="hoursWorked" required="true"
value="#myBean.hours">
<f:convertNumber locale="de" maxFractionDigits="2"/>
</p:inputText>
Now , if I enter a value such as 160ffff, the converter automatically strips off the letters after the digits whereas I would like to throw an error. How can I do it?
I have one label field which is license and I want give two license numbers for this..how to give two values here. I have one properties file (manageprofile) and one java class (manageprofiledatabean) which contains the license values
<h:outputLabel value="#('label.manageprofile.license')"/>
<h:outputText value="#{manageProfileDataBean.license}" />
<h:outputText escape="false" value=" "></h:outputText>
Concat both values in one string variable of manageProfileDataBean and then set it in
public class ManageProfileDataBean{
private String license = "";
private String val1 = "val1":
private String val2 = "val2";
public ManageProfileDataBean(){
license = val1+val2;
}
//setter getter
}
firstly, h:outputLabel is meant to be used for labelling input controls - it renders as the html <label> tag(e.g.)
<h:outputLabel for="myname" value="#{bean.labelValue}" />
<h:inputText id="myname" value="#{bean.name} />
If you need to specify multiple values in expression language you can do so like this:
<h:outputText value="#{bean.property1 bean.property2}"/>
so I guess in your case you would write it as
<h:outputText value="#{'label.manageprofile.license' manageProfileDataBean.license}" />
Finally, you don't need to use an h:outputText if you're not referenceing any propery so the last pair of nbsp characters don;t need to be in in outputText tag at all.
I wonder how to validate an inputText text field and see if it matchs a decimal format.
And also in the rendering time how to format that text field with a specific format
I've done this :
<rich:column id="soldes_comptables">
<f:facet name="header">
<h:outputText value="Solde Comptable" />
</f:facet>
<h:inputText id="inputTextSC" value="#{file.soldes_comptables}"
label="Montant"
style="border-color:#F2F3F7;"
validatorMessage="The number must be decimal eg: 000.00"
>
<f:convertNumber pattern="#,###,##0.00"/>
<f:validateRegex pattern="^[0-9]+(\.[0-9]{1,2})?$"></f:validateRegex>
<rich:validator />
</h:inputText>
<rich:message for="inputTextSC"/>
</rich:column>
but it's not working as i want :(. please help me
You're mixing validation and conversion. The <f:validateRegex> applies only on String values, not on Number values, however, the <f:convertNumber> has already converted it from String to Number beforehand, so the <f:validateRegex> is rather useless to you. You should remove it and specify the message as converterMessage instead.
<h:inputText ... converterMessage="The number must be decimal eg: 000.00">
<f:convertNumber pattern="#,###,##0.00"/>
</h:inputText>
An alternative would be to create a custom converter extending NumberConverter and throw a ConverterException on improper input format based on some regex pattern matching.
