Get all the children components recursively for all UI 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);
           };
       }
   }
}

Reset Binding Value from InputText in Oracle ADF

Use Case – We have one jsff page and contains some inputtext .On same page there is one Save button and one Cancel button.When user came to the page and try to enter some value in input text field and user click on Cancel button, its not resetting InputText value.When user come on same page again then he can able to see my previously entered value in Input Text though user clicked on cancel.

Normal developer will wrote Action Listener on Cancel Button and wrote below code

input.resetValue() ;
adfFacesContext.addPartialTarget(input);

But its will work (reset values).Setting value in input will not work like 

input.setValue(null);
or
input.setValue("");

Few developers will think, why cant we use resetActionListener. It will work for sure,but if you make autoSubmit of inputText to true, it will not work.
Reason- InputText has autoSubmit set to true, which submit the values to model immediately after updating it, resetActionListener resets values only if changes are not populated to model.

For this case use below code.Get current row and do REFRESH_FORGET_NEW_ROWS

    Row r1=vo.getCurrentRow(); 
    r1.refresh(oracle.jbo.Row.REFRESH_UNDO_CHANGES |  Row.REFRESH_FORGET_NEW_ROWS);  
or 
    r1.refresh(r1.REFRESH_UNDO_CHANGES | r1.REFRESH_WITH_DB_FORGET_CHANGES);

Note : If you don’t need autoSubmit, you can just remove it and use resetActionListener without any bean method to undo current row changes

It will reset binding value of input text.
