FM7 Portal Row Edits and Commits

I ran into an odd problem while working on my project management application in FileMaker 7. In one of my views, I have a portal in which the fields are enterable and editable "inline". You'll see in my picture that I have included a button that pops up a small detail window that shows users more details about that portal row and allows them to edit and add additional data to that portal row.

The crux of the problem is this. If you are "sitting" in a field in a portal row and then click the button (the blue plus sign) which does a "GTRR" (go to related record) of displaying it in a new, smaller window, you'll run into a record lock that prevents you from editing the record in the detail view because the lock from the referring window hasn't been released. If, however, we release that lock by committing the record BEFORE we do our GTRR, we'll lose the focused portal row and wind up going to the wrong related record (actually, always the first related record).

Solution
The idea is to be able to commit our record but still return to our portal row before doing our GTRR script. This is where script parameters come to our rescue. Pass the Get ( PortalRowNumber ) function as script parameter with that button. We can now safely commit the record, return to the portal row by the value of the script parameter and happily do our GTRR.
