For reference to anyone else who runs into this issue in the meantime, there are a couple of solutions; one is to ensure range
is always checked.
effect(() => {
const range = this.range();
this.calendarRef?.setInput('selected', range);
});
But I felt that this solution could be brittle; someone (even myself in the future) could easily come along and think that factoring out that variable is okay. That could be defended against with a comment like this that standardizes the practice of evaluating dependent signals unconditionally:
effect(() => {
const range = this.range();
// ^ Evaluate all signals first ^
this.calendarRef?.setInput('selected', range);
});
But the solution I settled on instead was to turn calendarRef
itself into a signal. Then the optional chaining all works as expected.
effect(() => {
this.calendarRef()?.setInput('selected', this.range());
});
