How to display custom FormBuilder error

Created 7 years ago by pepijn

I made a FormBuilder with a custom Handler. In the handler I'm importing a bunch of entries based on third party URL's. For some URL's, this process fails and I want to be able to flash a custom error message.

The code below doesn't produce any flash messages. What am I doing wrong?

    public function handle(FormBuilder $builder) {
        $urls = (array) $this->getUrls($builder);
        $result = $this->dispatch(new ImportEntries($urls));

        // this doesn't seem to work
        $builder->addFormError('somefield', 'some message');
        $builder->flash();
    }

This is used in the front end via the form function? If so you don't need the flash there. That's probably wiping it before the FormController flashes it itself here: https://github.com/anomalylabs/streams-platform/blob/1.1/src/Http/Controller/FormController.php#L42

@ryanthompson This is a FormBuilder for the admin (not used in frontend, no custom twig templates). When I remove the flash line, the flash messages are still not shown.

The handler is defined on the FormBuilder as follows:

protected $actions = [
        'import' => [
            'text' => 'Import',
            'type' => 'success',
            'handler' => ImportFormHandler::class,
        ]
    ];
