Hi,

The problem is in the page life cycle, where the page already has loaded the content and then you press the OK button to save it, but this is only saved in the edit view, since this is the next step in the life cycle. The preview is loaded before this in cycle, so therefore there are old data. I hope it makes sense.

The easiest solution to this is after you save the data, after the OK click, you need to perform URL redirection on the page on it self - it is kind of refresh, so the new values will be loaded in the preview of the form.

Best regards,
