Subject: Bugfix: Get the FSS Embedded List Read working as expected based on runtime tests.
X-Git-Tag: 0.6.12~7
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=f75b5ee4f368e5a5f6a97a4de0d6a784c12c7e11;p=fll

Bugfix: Get the FSS Embedded List Read working as expected based on runtime tests.

A good portion of clean ups and design changes to address special cases or anything overlooked.
The runtime tests now pass as expected.

There are still some situations that need to be fixed.
