                      QUESTION

                      How to delete all components in a form on Codenameone?

                      Asked 2021-Jun-11 at 10:32

                      I am writing a program in Codenameone that will pull an array of products from a url and display them in a list. I want to reload the page every time I press a button, so I code in a method called reload that should delete everything in the form and then replace it all with the newly pulled list.

                      public void reload(Form list){
                          list.removeAll();
                          list.repaint();
                          list.add(lpanelf);
                      
                      
                          pull();
                      
                      
                          for(int i=0; i<(products.size());i++){
                              System.out.println(products.get(i));
                          }
                          for(int i = 0; i<(products.size()/2);i++){
                              list.add(createWidget(products.get(i*2),products.get(i*2+1),i));
                          }
                      
                      
                      
                          list.addComponent(lpanelb);
                      
                      }
                      

                      And createWidget is:

                      public SwipeableContainer createWidget(String product, String amount,int i) {
                      
                          MultiButton button = new MultiButton(product);
                          Button buttonb = new Button("DELETE");
                          deleteb.add(button);
                          slide.add(buttonb);
                          button.setLayout(new GridLayout(1,2));
                          button.add(amount);
                          return new SwipeableContainer(slide.get(i),deleteb.get(i));
                      
                      }
                      

                      After the first time it reloads, it throws:

                      java.lang.IllegalArgumentException: Component is already contained in Container: Container[x=0 y=0 width=1125 height=165 name=null, layout = BorderLayout, scrollableX = false, scrollableY = false, components = [Button]].

                      I think the problem is that removeAll isn't actually removing all the swipable containers and so it won't let me create new ones in their place but I am not too sure. Any help would be greatly appreciated.

                      removeAll() doesn't recurse. That would be expensive and often redundant since the GC usually removes the entire tree.

                      Typically these problems are pretty simple to workaround though. There are two approaches:

                      • Stop caching the component and re-create it every time you reload. This will mean it's never "already in" something

                      • Before adding the problematic component just do: problematicComponent.remove(). This will remove it from its parent (or do nothing if it has no parent)

                      In your case it seems like you're doing this:

                      return new SwipeableContainer(slide.get(i),deleteb.get(i));
                      

                      After doing stuff linke this:

                      slide.add(buttonb);
                      

                      So you added buttonb to slide. That means that buttonb.getParent() == slide. Then you create a new SwipableContainer and try to add into it a component that's already in it.

                      I'm guessing here since you didn't say which specific line threw the exception but on that line you will find the problematic component.

                      Also this line is problematic: button.add(amount);

                      You're relying on the fact that MultiButton inherits from Container but that's fragile behavior. You should use one of the set text line methods.

                      Install CodenameOne

                      TIP: We are currently transitioning to Maven, and have created a new, simpler method for creating projects. Check out https://start.codenameone.com to get started now.
                      NOTE: We are in the process of migrating from Ant to Maven, which simplifies the process for building from source. See Ant Quick Start for the legacy Ant build instructions. The setup is covered in depth in this article and video. IMPORTANT: Building Codename One requires JDK 8, currently. You cannot use JDK 11 as some sub-modules must use -source 1.5 and -target 1.5 to maintain backward compatibility with parts of the toolchain.
                      This will build and install Codename One in your local Maven repository. This process can take a while since it automatically downloads dependencies with a size of ~1GB.
