Hi,

I'm trying to build a custom page following the tutorial:
http://devs.x-cart.com/en/basics/new_form/model_editing.html

However, when I try to add the widget to the twig file, an error occurs (error log is below). Controller is VendorRegistration.

Any ideas why this happens?

Thanks a lot!

If anyone encounters this error: in my case it was due to inappropriate field class for type parameter in schema.

Following the same tutorial, I created a new form model and when I open the form, enter some text in the field and then leave the field, the field is emptied. It is done from JavaScript, but I am not able to understand why it happens.

As far as I could see, it only happens with Symfony types and not with ones defined by X-cart, but the X-cart does not offer types such as email, password etc that extend Symfony\Component\Form\AbstractType.

I have been through the developer site and followed the tutorial for creating editable form model, but still could not solve the problem.

Do you have any suggestions?

Thanks!

I believe you cannot use Symfony types without a wrapping class in X-Cart 5. Please check existing classes in \XLite\View\FormModel and \XLite\View\FormField namespaces.

As for JavaScript emptying your custom field: I think this may happen because of Vue.js. Recent XC5 versions use Vue.js for some of forms, and this library maps data in JavaScript model objects to form fields automatically. Perhaps, your custom field is not mapped, so it stays empty. Please check how existing fields use the "v-model" attribute.

Some of the X-cart classes use Symfony types directly. I also tried to wrap Symfony type in the same manner the X-cart classes do. None of these helped.

What did work though is switching to the way described here:

http://devs.x-cart.com/en/basics/model_editing_page.html

It seems to be the older approach, but it works.
