FlashMessages don't work after redirect

Hey guys, I read through all the post about this topic but to no avail. My problem is flash messages don't show after redirect (They work well without redirecting).
I don't know where to look. The app is relatively clean sandbox nothing special.
My URL after redirect looks like this:
http://localhost:88/?_fid=sdz1
And bdump of session on target page is here.
I don't know where to look and what piece of code to post.
I generate flash messages as simply as this:
$this->flashMessage('foo');
$this->redirect(":Homepage:Index:default");
I am on 3.0 beta.

Hi. Do you have code to draw them in you Homepage:index:default latte file ? ?
taken from docs
{foreach $flashes as $flash}
<div class="flash {$flash->type}">{$flash->message}</div>
{/foreach}
Make sure you have something like this in your template file of the page you're redirecting to

Yes, sure, I have that code in my layout that is extended by action templates. Just to make sure the template is fine I tried this action:
public function actionDefault()
{
$this->flashMessage('foo');
}
and the flash message is rendered.

I think the best way is to step through the code and see why it does not pass session data to the template.

Yeah, I love Xdebug, but in this case it is a bit problematic, with the nature of the flashmessages (session, redirects, 3 seconds expiration), but I'll try harder ;-)

Looks like: \Nette\Application\UI\Component::getParameter
returns false ($this->params === []
) even if I can see the
parameters in the URL. Will try to look further into this.

However when I bdump $this->getParameters in the action code. It contains the params. Looks like something is called in the wrong order.

Hah, found it!
I had a presenter code like this:
/**
* @param \Nette\Localization\ITranslator $translator
*/
public function injectTranslator(\Nette\Localization\ITranslator $translator): void
{
assert($this->template instanceof \Nette\Bridges\ApplicationLatte\Template);
$this->template->setTranslator($this->_internal_translator);
}
… and changed it to:
/**
* @var \Nette\Localization\ITranslator $translator
* @internal
*/
private $_internal_translator;
public function beforeRender() {
assert($this->template instanceof \Nette\Bridges\ApplicationLatte\Template);
$this->template->setTranslator($this->_internal_translator);
}
/**
* @param \Nette\Localization\ITranslator $translator
*/
public function injectTranslator(\Nette\Localization\ITranslator $translator): void
{
$this->_internal_translator = $translator;
}
Thanks @dg for extra motivation!!!
Btw, isn't there a way to register translator to template factory somehow? Or what is the best practice for setting the system-wide translator? I hate setting translator for presenter, email templates and maybe even form, separately.
