New nodes set to 'browse mode' lack a layout and throw "Error #5"

(FYI - as I was setting the project info this bug, I realized there was a flurry of releases in the past week and this might be fixed in the latest version.... if you're using this module and you're not ready to upgrade, this might yet be a solution for you.)

1. Go to node/add/filemaker
2. Provide "Title"
3. Set "FileMaker feature to use for default Drupal view" to "browse mode"
4 Click "Save"

You receive a blank content area, save for the following error message:

"Error #5 : Command is invalid (for example, a Set Field script step does not have a calculation specified)"

This is one of those annoying catch-all errors for the Filemaker PHP API, and might as well say "There's an error." Fortunately I was able to pin it down. When you create a new Filemaker node you're sent, as is default Drupal behavior, to hook_view(). In this modules case, it when going to the view page with tab type set to 'browse', there's no check for a layout. The module and the Filemaker API try to create a new FindCommand, which lacks a layout and the API request bombs. So, I recommend inserting a check for the layout, and if its not find, directing the user to the proper configuration form.
