Error when editing entities with nullable @OneToOne relationships #49

Closed the-mars-rover closed 1 month ago

the-mars-rover commented 1 month ago

Describe the bug When an entity has a nullable @OneToOne relationship with another entity, editing the entity leads to a Thymeleaf error (see stack trace below) and problems in displaying the edit page (see screenshot below).

Is the bug at startup before you perform any action? No

Awesome!

I'm no expert in Thymeleaf but, if I have time, I'll also try make a small contribution and submit a PR :-)

Also, while I'm here: awesome project man.

aileftech commented 1 month ago

Thank you, I really appreciate it!

If you want to try and fix it you should do as follows: where you see the code

object != null ? object.traverse(field).getPrimaryKeyValue() : ''

It also need to return the empty string if object.traverse(field) is null as well :)
