ui:repeat in Java class

Hi,

To achieve ui:repeat in Java class.

The object to be looped on must be list or an array.

 //It is the context called by current threads request  
 FacesContext context = FacesContext.getCurrentInstance();  
 // Application instance associated with this web application.  
 Application application = context.getApplication();  
 //Here component type will be facelets.ui.Repeat  
 UIRepeat repeat= (UIRepeat) application  
                 .createComponent(UIRepeat.COMPONENT_TYPE);  
                 //Here the ID is set  
                 repeat.setId("repeatGrid");  
                 //The variable name is set  
                 repeat.setVar("value");  
 //used to calculate the value for the specified attribute or property name, if any  
 //Here the value is set for “value” attribute  
                 repeat  
                 .setValueExpression(  
                                 "value",  
                                 getValueExpression(fc,  
                                                 "#{valueList.value}"));  

You can add “repeat” variable to "parentObject"(parent object) by using

 parentObject.getChildren().add(repeat);  

This implementation was done for the dynamic population through methods inside java classes.

You can implement in jsf simply through this.

 <ui:repeat var=" value " value=""#{valueList.value}">  
         <h:outputText value="#{ value }”/>  
 </ui:repeat>  

Thanks.
