SelectOneMenu Validation

[Mal Tec]

hi

i need to validate the selectoneMenu in JSF. I'm using

 <h:selectOneMenu required="true" id="country" value="" >
                                        <f:selectItem itemLabel="--Select--" itemValue="#{null}"/>
                                        <f:selectItem itemLabel="India" itemValue="India"/>
                                        <f:selectItem itemLabel="India" itemValue="India"/>
                                        <f:selectItem itemLabel="India" itemValue="India"/>
                                    </h:selectOneMenu>

using properties for error msg:

javax.faces.component.UIInput.REQUIRED=Please enter a value for this field.
javax.faces.component.UIInput.CONVERSION= Conversion Error Occured
 
javax.faces.component.UISelectOne.INVALID= Invalid Selection

i get UIInput.REQUIRED's error: Please enter a value for this field on selecting option Select with value null.. I want to get special error for UISelect like...

javax.faces.component.UISelectOne.REQUIRED = Select Appropriate Value

or need to fire it thorugh Invalid

javax.faces.component.UISelectOne.INVALID

How it can be done? Or if any tother alternative available.

Hi,

1) if you are allowed to use tomhawk library then correct your code as follows

<h:selectOneMenu required="true" id="country" value="" >  
    <f:selectItem itemLabel="--Select--" itemValue="?"/>  
    <f:selectItem itemLabel="India" itemValue="India"/>  
    <f:selectItem itemLabel="India" itemValue="India"/>  
    <f:selectItem itemLabel="India" itemValue="India"/>  
<t:validateRegExpr pattern="[^?]" summaryMessage="please provide appropriate value" />
</h:selectOneMenu> 

if you want you can pull the summary message from property file and change as you like

2) write a custom validator and divert the flow to your custom validator and write the logic in java class.

3) you can write a listener and write the appropriate logic before validation phase.
