Community Builder registration loses menu Itemid on submit

Hello,We have identified what appears to be a routing issue with the Community Builder registration form on Joomla 6.We have a published Joomla menu item for CB Registration: French menu item:

• Title: INSCRIPTION
• Alias: inscription
• Itemid: 103
• Language: fr-FR
• Published: Yes

The registration page itself works correctly.However, the generated registration form action is: and contains no .After successful registration, the user therefore ends up on: instead of remaining within the registration menu context.This also causes our T4 template to fall back to its home layout ( ) on the post-registration page, and the normal Joomla system message is not displayed.We traced the generated form action to: where it uses: We then traced to: It calls: For this request, the view is .In , therefore looks for a published Joomla menu item whose link matches: Our Registration menu item naturally uses: There does not appear to be any mapping from the processing view back to the registration view .Could you please confirm whether this is expected?Should a CB registration form generated from a menu item preserve that menu Itemid when posting to ?We would expect the POST processing URL to retain the Registration menu context so that the normal Joomla template layout and system messages remain available.We would prefer not to patch CB core files if there is an existing configuration or supported solution for this.Thank you.

This is expected. That's not a valid menu endpoint as it's an internal response page. So it won't have an Itemid. That's generally the purpose of default layout is to handle internal response views like that.

We however have been adding support for creating menu items to internal response pages like that to allow for better customization. Have added a feature ticket to expose more of CBs internal views for Joomla menu creation.

The easiest workaround is to use onAfterSaveUserRegistration in CB Auto Actions and redirect them to your own custom registration complete page. In the future we'll expose a parameter to let you configure this from CB > Configuration > Registration to remove the need for CB Auto Actions here.
