Attention to all extension developers: We’ve encountered an issue with the newest(s) shell versions and older Rancher systems, where table columns using formatters won’t show those values. Areas affected • Shell versions with compatibility problem:

3.0.8

and

3.0.9

• Rancher systems where using Shell

3.0.8

and

3.0.9

we might see problems:

2.10

,

2.11

,

2.12

and

2.13

Problem Rancher’s shell renamed the global Vue property that exposes the extension manager from

$plugin

(older versions) to

$extension

(newer versions). Shell components such as

SortableTable

were updated to look up extension-registered formatters via

this.$extension.getDynamic('formatters', ...)

. However, older Rancher hosts only inject

$plugin

onto

vueApp.config.globalProperties

— leaving

this.$extension

as

undefined

— so any formatter registered by an extension is silently invisible to the table. Root cause The extension manager is injected into

vueApp.config.globalProperties

by Rancher’s

inject()

mechanism inside

installInjectedPlugins

. Depending on the Rancher version, it is injected as either

$plugin

or

$extension

, but not necessarily both. The context object passed to an extension’s init function carries a reference to the

Nuxt

app (not the Vue 3 app), so

context.app.config.globalProperties

is undefined — making it impossible for an extension to self-patch the missing property using only what Rancher passes in. What to do Developers that are using Shell versions

3.0.8

and

3.0.9

should update to version 3.0.10 and release a new version of their extension
