Hi everyone,
I have created my form wich contains fieldset. I retrieved my form parameter in my fieldset and I have to use it to add where clause to populate my select Element.
Unfortunately my parameter is null sometimes. I post here my code for appreciation.
My RapportEffetForm below

$this->setName('RapportEffetForm');
$this->setAttribute('class', 'form-saisie');
//$this->addFieldset(RapportEffetFieldset::class,['use_as_base_fieldset' => true]);
$this->addFieldsetWithParameters($myFieldset,['use_as_base_fieldset' => true]);
$this->addSubmitButton('next', 'Poursuivre', 'next', 'btn btn-vert w-100');

My RapportEffetForm instantiation in my controller :
`$rapportEffetForm = $this->formManager->get(\Commun\Form\Modules\Application\RapportEffetForm::class,['id' => $id]);`
To @froschdesign , I would like to say I would follow your advice about removing the mappers in my form constructor, but for now I would like to get my option array for my select element dynamically but my $idProjet in my fieldset return null.
Any advice or help please ?

Uff, this is confusion:
- `CommunForm`?
- `CommunFormFieldset`?
- `RapportEffetFieldset` vs. `EffetRapportFieldset`
The property `$params` is missing in `RapportEffectForm` and in `EffectRapportFieldsetFactory` the parameters always passed as empty array to the fieldset. It looks like something is missing here.

CommunForm is a generic form class which all form extend but I really do not use it except for creating submit input.
CommunFieldset is my generic fieldset that all fieldsets extend.
RapportEffetFieldset and EffortRapportFieldset are different. Maybe I need to rename them correctly but everything is OK except my parameter.
In EffortRapportFieldsetFactory, how to correctly set my params?

Compare the factories: `RapportEffetFieldsetFactory` vs. `EffetRapportFieldsetFactory`
The part for the parameters is missing in `EffetRapportFieldsetFactory`.
I suggest to use a debugger to check the creation of the fieldset and the way of the parameters array.

That’s my question. How can I do it correctly? I tried with options parameters but I get null value

You must add the same code for handling `$params` from the class `RapportEffetFieldsetFactory` to `EffetRapportFieldsetFactory`.
If you want to have access to the parameters in `EffetRapportFieldset` then it must be passed.
_(Unfortunately, I cannot check the code myself, as not everything is shown here. So it is realistic that more needs to be done.)_

OK. I will try and get back to you very soon.

'allow_add' => $allowAdd,
'target_element' => [
'type' => $this->getStringFromElement($targetElement),
],
],
'attributes' => $attributes,
]);
}
}
```
When I make a var\_dump in my init() function in EffetRapportFielset, I get this
And in the same page I get also this :
I need to say that when I do echo on $this-\>parameters on my RapportEffetForm I get my correct parameter value.
I do not know why for the first time, the value is good, and the (2nd time ??) is null. Do not know also why this value is shown twice.
Here are all my infos. Hope it helps you to also help me finding a solution 🙄

Problem solved by class my fieldset with
`$this->getFormFactory()->getFormElementManager()->get(EffetsProjetSelect::class, ['params' => $this->params])`

I searched further and I think that this problem may also apply to you:

The `create` method of `Laminas\Form\Factory` must be updated:
```php
public function create($spec): ElementInterface
{
$spec = $this->validateSpecification($spec, __METHOD__ );
$type = $spec['type'] ?? Element::class;
$element = $this->getFormElementManager()->get(
$type,
$spec['options'] ?? null // this is missing!
);
// …
}
```

Thank you very much @froschdesign , This is what I used and I solved it partially but I’m facing to a new problem I posted 8m ago. See the link below please :
