How to register actions programmatically with NetBeans Platform

Thanks Mark, I think I'm on the right track.

I'm now trying to create the instance as an action (So that it shows up in the Keymap), then create a Menu shadow entry, finally the shortcut shadow entry with a default value.

The action seems to be created now but the shadow entries are not working (Including the menu which was working earlier).

This is what I have so far:

Code:

    private void registerAction(String name, String category, String shortcut, String menuPath, Action a) throws IOException {
        ///////////////////////
        // Add/Update Action //
        ///////////////////////
        String originalFile = "Actions/" + category + "/" + name + ".instance";
        FileObject in = getFolderAt("Actions/" + category);
        FileObject obj = in.getFileObject(name, "instance");
        if (obj == null) {
            obj = in.createData(name, "instance");
        }
        a.putValue(Action.NAME, name);
        obj.setAttribute("instanceCreate", a);
        obj.setAttribute("instanceClass", a.getClass().getName());

        /////////////////////
        // Add/Update Menu //
        /////////////////////
        in = getFolderAt(menuPath);
        obj = in.getFileObject(name, "shadow");
        // Create if missing.
        if (obj == null) {
            obj = in.createData(name, "shadow");
            obj.setAttribute("originalFile", originalFile);
        }

        /////////////////////////
        // Add/Update Shortcut //
        /////////////////////////
        in = getFolderAt("Shortcuts");
        obj = in.getFileObject(shortcut, "shadow");
        if (obj == null) {
            obj = in.createData(shortcut, "shadow");
            obj.setAttribute("originalFile", originalFile);
        }
    }

    // This helper seems to work fine
    private static FileObject getFolderAt(String inputPath) throws IOException {
        String parts[] = inputPath.split("/");
        FileObject existing = FileUtil.getConfigFile(inputPath);
        if (existing != null)
            return existing;

        FileObject base = FileUtil.getConfigFile(parts[0]);
        if (base == null) return null;

        for (int i = 1; i < parts.length; i++) {
            String path = Joiner.on('/').join(Arrays.copyOfRange(parts,0,i+1));
            FileObject next = FileUtil.getConfigFile(path);
            if (next == null) {
                next = base.createFolder(parts[i]);
            }
            base = next;
        }

        return FileUtil.getConfigFile(inputPath);
    }
