Error with dynamical form rendering in 1.7.8.1

[krekken]

Prerequisites

• I understand and accept the project's code of conduct
• I have already searched in existing issues and found no previous report of this bug.

Describe the bug and add screenshots

When i wan't to use a form, where my entity is dynamical from the database, with a form structure like this:

{{form_start(form)}}
{# form content #}
{{form_end(form)}}

I get this error message.

If i use {{form(form)}} it actually works, but thats not good for me, cause i want to customize the template.

Expected behavior

Expected behavior is to successfully display my form, instead of getting an error message

Steps to reproduce

I made an example module, which can reproduce this bug.
https://github.com/krekken/formbugreproduce

if you install it on a 1.7.7.8 prestashop it will work, but it won't work if you install it on a 1.7.8.1 container.

the Form Bug Reproduce tab is the one, which contains the bugged form

PrestaShop version(s) where the bug happened

1.7.8.1

PHP version(s) where the bug happened

7.4.25

If your bug is related to a module, specify its name and its version

No response

-form(form) works but not form_start(form)

• fine with 1.7.7 but not 1.7.8

Hello @krekken

Following these steps, I had no issue:

1. Clone your module under /modules
2. Access to BO>IMPROVE>Modules>Module Catalog
3. Install the module
4. Click on Configure button
5. Save the configuration
6. Success => no error

Is there a missing step to reproduce the issue?
Please check and feedback.

Thanks!

i added a tab, and if you click on that you'll be able to see the bug. its either working if you're using 1.7.7.8, or not if you're using 1.7.8.1

i edited the issue, so it says so now

that is a different error. i updated the module, so if you re-download it, and install it again, it should now handle french, and show you the actual error.

i replaced the language name with "placeholder" so if you download it again, and reinstall it, it should work, with every language name now

Hello,

I did'nt manage to reporduce the issue on PS1778. So, it's a regression.

I'll add this to the debug backlog so that it's fixed.

Please be aware that due to the high number of reported issues, some bugs might take a very long time to be resolved.
If you manage to get the problem fixed, then please contribute the fix back to the project as a Pull Request. Remember that the more people contribute, the better PrestaShop becomes for everyone.

Thank you!
