TYPO3 Core

Hi,

I use a form to register a user, it works fine in version 9.5.9 (not really sure of the exact version but it worked in a 9.5 version less than 9.5.10) but now that I upgraded to 9.5.11, the controller action (i.e. : create) is no more called, instead, the default action is called it look like the request parameters are ignored.

I've seen that the url changed.

Current uri not working :

/member/register
?s168cfd818c624a202c543af315db68c=Member
&we12a13bddd5a5b908a01faba7c1f133=create
&cHash=eabaac9eeff7a6d7db7ed1468db9530a

Working uri before v9.5.10 :

/member/register
?tx_myext_myplugin[controller]=Member
&tx_myext_myplugin[action]=create
&cHash=eabaac9eeff7a6d7db7ed1468db9530a

This happens in PageRouter::generateUri() with option 'deflatedParameters', if theses lines are commented, everything works fine :

if ($route->hasOption('deflatedParameters')) {
   $parameters = $route->getOption('deflatedParameters');
}

Here is the form that I used :

<f:form action="create" enctype="multipart/form-data"  name="newMember" object="{newMember}">
    ...
</f:form>

It's the same with all forms.
