You should not. Components know their parent, parents don’t know their children (child components). Technically you can, but it is difficult and I won’t show you how because is it just the wrong way to use WO. What you want reflects a misunderstanding of WO. You are working against the tool, not with it. If you will provide mode details on what you want to accomplish (now how you want to do it), I think we can show you the right way to use WO. Start with: - why do you want to call setResponse(“”)? That is intended to hold what the user has input. The parent component should never have access to that value - when (what conditions) do you want to set this to “”? If you are trying to clear it after a failed validation attempt, perhaps there is simply a bug here: https://github.com/molequedeideias/wonder/blob/00e813f91664a1df1a84902e03175e4a34cf7d0f/Frameworks/Misc/ERCaptcha/Sources/er/captcha/ERCaptcha.java#L94 And after that should be: _response = null; Perhaps resetCaptcha() should do that too. Keep in mind, I have never seen this code before today and have no idea if that is the version you are using. :-) That was the first hit in Google.
