Theming | Scoped Tokens only evaluated once

[jogerj]

Describe the bug

I'm following the instructions from https://v18.primeng.org/theming#scopedtokens

So with the example provided, I tried to add conditional clauses on which color is passed to the [dt] attribute depending on another value. This value apparently is only evaluated once on render, the color doesn't change. See example provided and click the button to change the value. The reproducer defines customSwitch which would be based on amberSwitch from provided example in docs.

workaround right now would be to provide multiple customSwitch objects and pass them to [dt] conditionally

<p-toggleswitch [(ngModel)]="checked2" [dt]="toggleColor ? amberSwitch : slateSwitch" /><br/>

Environment

windows with node 22.8.0

reproducer runs on node 18.20.x

Steps to reproduce the behavior

See above reproducer and click on the button to change the value of the colorToggle. when changed, then value of customSwitch should change, and value passed to [dt] input should change, but the component does not reevaluate it.

Expected behavior

Either this is intended behavior (which should be documented) or the value of customSwitch should be reevaluated if changed.

turns out to be intended
