I have a layout that is rendered via IWP in FileMaker 12. On this layout I have a portal that displays related records (attachments). The process to add an attachment includes going to a new layout (which contains the SuperContainer web viewer) and creating a new record, adding the file, and then clicking a button which takes you back to the parent record. For some reason, when I navigate back to the parent record/layout, the portal doesn't show the record I just added. If I navigate to another layout and then back again, it shows fine. I also confirmed that it works as expected if I do the same process in FMP. I've modified the nav scripting to include multiple refresh window steps.. I've performed a find for the parent record in question, and I've even tried to go to the previous record and then to the next record to see if that helps, but it does not. Any ideas on other ways to refresh the window or what else I can check?

OK.. I figured it out. It had to do with a portal filter.
