Dynamically change min/max backend date field (dependsOn)

[ericp-mrel]

Hi,

Is it possible to have two date fields e.g. start date and end date where end date is dependent on the start date. So, when a user selects a start date, the end date cannot be earlier than the start date?

I've tried to accomplish this using the filterFields method on my model, but I'm assuming the JS widget isn't re-adjusting it's settings as I update the minDate config value from the backend code.

Any help is appreciated.

Thanks!

Entry.php:

    /**
     * @param object $fields
     * @param string|null $context
     * @return void
     */
    public function filterFields($fields, $context = null)
    {
        trace_log($fields->entries_end_date);

        if ($fields->entries_start_date->value) {
//            $fields->entries_end_date->minDate = $fields->entries_start_date->value;
            $fields->entries_end_date->config['minDate'] = $fields->entries_start_date->value;

            trace_log($fields->entries_end_date);
        }
    }

fields.yaml

fields:
    name:
        label: Name
        span: left
        required: 1
        type: text

    entries_start_date:
        label: 'Start Date'
        mode: date
        span: left
        required: 1
        type: datepicker
    entries_end_date:
        label: 'End Date'
        mode: date
        span: auto
        required: 1
        dependsOn:
            - entries_start_date
        minDate: '2022-12-01'
        type: datepicker
