Re: how to hide the AjaxFallbackButton when the number of Models is larger than a specific integer

[extraquoo]

Hi ,

Thanks for you reply. I remove my method  hideAddButton()  from
phoneListView 

then I create a new ajaxcallbackbutton method to carry your code like below 

public Button getLimitedPartialRefreshAddButton(String id, final int
limited) {
                return new AjaxFallbackButton(id, null) {

                        /** Default serial id */
                        private static final long serialVersionUID = 1L;
                        
                        @Override
                        public boolean isVisible() {
                                return isEnabledInHierarchy();
                        }
                        
                        @Override protected void onConfigure () { 
                                  super.onConfigure(); 

                                  setVisible (getList().size() < limited); 
                                } 

                        @Override
                        protected void onSubmit(AjaxRequestTarget target, 
Form<?> form) {

                                List<T> targetList = 
PartialUpdateListView.this.getModelObject();
                                targetList.add(createNewItem());

                                if (target != null) {
                                        setResponsePage(getPage());
                                }
                                
                        }
                }.setDefaultFormProcessing(false);
        }

then add this button in the phoneViewList :

newPhone.add(phoneListView.getLimitedPartialRefreshAddButton("addNewPhone",
ADD_MORE_LIMIT_TWO));

the button is not hidden when I add phone panel twice.

any suggestion ?
