Fatal errors when switching to "Registration Link" or "Registration Form" field formatters

Thanks for the report, I will take a look soon.

Thanks John.
Tell me if you need a dump of the test site.

That would be great @pmunch - I just sent you my email address via Drupal contact form. Thank you

Same here, D 9.5.2, Php 8.1.14, latest beta module in a wodby docker setup with Drupal managed by composer. Maybe unrelated - the unpaid test orders (manual payment) can be seen in the orders view of commerce as complete (although pending in the payments subtab) but never arrive in the prod. variations‘ registration tabs despite using custom event order item and order types. Promoting the payment status to complete doesn‘t move the reg. into their slot, which may be intended, however? Regards, dgwolf

Reproduced issue locally using the site dump from @pmunch. Have to take care of something other things right now but should be able to debug and commit a fix within the next day or two. Most likely the issue with unpaid test orders is unrelated, that may become a separate issue. More soon.

@pmunch, I'll push up fixes within the next day for you and anyone else that is using commerce in this way. The reason I hadn't seen this issue before is you are not using an Add to Cart form for your product, which one would typically do if you have commerce installed. Maybe you were going to get to that eventually, but briefly, to make things work better, you would use these admin pages to setup an Add to Cart form on your product detail page:

admin/commerce/config/product-types/event/edit - check the box for "inject product variation fields"

admin/commerce/config/product-variation-types/event_offer/edit/display - adjust the weights of fields here (manually if necessary) to get the product page to show things in the order you want - Registration should not be an enabled field since there is a special form in checkout

admin/commerce/config/product-types/event/edit/display - hide the Variations label and change the format for it to "Add to cart form"

admin/commerce/config/order-item-types/default/edit/form-display/add_to_cart - change the widget for Purchased Entity to "Product variation title (spaces available)" - that should be the only enabled field

If you do those things you will avoid the exceptions you reported and make better use of the module. The idea is that people register via checkout and not from the product page.

Hi John, many thanks for your return.

I'm an experienced Drupal integrator, but this is my first real approcach with commerce, so sorry if I still miss some concepts or best practices.

As you mentionned, I was on the track to not use the Add to cart form, to keep the process straightforward as only registrations are sold.

While awaiting your fixes, I will however setup the solution you suggest to see how it fits with the project.

No problem @pmunch, the flow will vary for different sites.

Fix committed and will be in a new release within a couple days.

@dgwolf, registrations should show in their respective tabs - if you don't mind can you open a separate issue for that so we can track it. Also let me know if you can provide a site dump to help with debugging. Thank you.

Thanks a lot John.
