I'm currently using the gform_after_save_form hook but I'm not getting the changed values unless I save it twice. I investigated the issue and it looks like the
RGFormsModel::get_form_meta($id); in form_detail.php is returning a cached form meta.
Steps to reproduce:
1) Add a hook for gform_after_save_form. code something so you can see the title of the saved form.
2) Open an existing form.
3) change the title.
4) save it.
5) The code from step 1 outputs the old title (at least for me anyway).
Please let me know if you can reproduce this or if something could be wrong with my setup/environment.
