cache()->preload() prevents items from being built?

[Jan Romero]

Hi everyone,

I’ve come across this phenomenon where WireCache never builds cache entries if they were previously attempted to preload. Just wondering if anyone has any experience with preloading WireCache items? Am I doing something wrong?

I’ve described the issue here: https://github.com/processwire/processwire-issues/issues/1604

Here is the code I’m using:

cache()->preload([ 'imaginary', 'names' ]); //these don’t exist.

//now cache()->preloads is [ 'imaginary' => '', 'names' => '' ]

$freshlyGeneratedValue = cache()->get('imaginary', WireCache::expireDaily, function() {
    return 'so fresh'; //this never happens
});

var_dump($freshlyGeneratedValue); // string(0) ""

Thanks!
