Overview

The fusionSpan Common Base Library is a shared, no-namespace package of reusable Apex constants, a dynamic picklist component, and a generic key/value Custom Metadata store. It doesn’t do anything on its own — other fusionSpan accelerators (such as Roster and New User Registration) declare it as a required prerequisite and build on its shared pieces instead of each reimplementing the same plumbing.
If a dependent accelerator’s setup instructions say to install the Common Base Library first, install it before the accelerator itself — the dependent package’s components reference this library’s classes and objects directly.

​
What It Provides

  • FS_Constants__mdt — a generic key/value Custom Metadata type that dependent accelerators use to store their own configurable settings. It ships empty; accelerators or admins add records to it as needed.
  • FS_Picklist — a reusable Aura picklist component that dependent accelerators can drop onto record or community pages.
  • Shared Apex constants and dynamic picklist logic that other accelerators’ Apex code calls into directly.

​
How to Configure

There is nothing to configure in the Common Base Library itself after installing it — it’s purely a prerequisite. Install it, then install whichever accelerator requires it.

​
Limitations and Common Pitfalls

  • Install order matters. Dependent accelerators reference this package’s classes and Custom Metadata type by name; installing them before the Common Base Library causes the install or deployment to fail.
  • No namespace, so no built-in collision protection. Because this is an unmanaged package, its components live in your org’s default space with only an FS_ prefix as a guard. Because it’s unmanaged, they can also be edited or deleted after install — treat them as read-only, since editing or deleting them can break every accelerator that depends on them.
  • Version compatibility is set by each dependent accelerator, not by this package — if a dependent accelerator’s setup steps call out a minimum Common Base version, follow that rather than assuming any installed version works.
