Tag: Components

Problem- Need to reset all the input Components in the page on the click of a button.On first thought developer think of do this in the bean by getting the binding of the outermost layout component and then using the getChildren() method for that UIComponent.Then for all the UI components in the list,set the reset property to true.But problem here is that page contain multiple layout components. And getChildren() method would not recursively search for all the UI components (including inside the other layout components such as panelgrouplayout.

Implementation – Its plain java.Call the method recursively.get each input Component and reset it.

// reset all the child uicomponents
private void resetValueInputItems(AdfFacesContext adfFacesContext,
                                 UIComponent component){
   List<UIComponent> items = component.getChildren();
   for ( UIComponent item : items ) {
      
       resetValueInputItems(adfFacesContext,item);
      
       if ( item instanceof RichInputText  ) {
           RichInputText input = (RichInputText)item;
           if ( !input.isDisabled() ) {
               input.resetValue() ;
               adfFacesContext.addPartialTarget(input);
           };
       } else if ( item instanceof RichInputDate ) {
           RichInputDate input = (RichInputDate)item;
           if ( !input.isDisabled() ) {
               input.resetValue() ;
               adfFacesContext.addPartialTarget(input);
           };
       }
   }
}
