Unable to restore an entity form when no changes were made in the dataset

[dbemke]

Problem description

According to https://docs.google.com/document/d/16S_7SPlN8K4gsRufeOvM7nOqhpVLDWiRhQxERnCF4h4/edit?tab=t.3j8lit4lp0km#heading=h.p4gnm86e8z1v "deleted forms can be restored only if the dataset or properties in the dataset have not been deleted" .
If I publish an entity form and delete it (without making any changes in the dataset), I'm not able to restore the form. There is information "This Form cannot be restored because the related dataset(s) has been modified or deleted."

Steps to reproduce the problem

1. Publish an entity form.
2. Delete the form.
3. Try to restore the form.

Expected behavior

It should be possible to restore the form if there weren't any changes in the dataset.

Can you please more information. What Form did you use? can you please provide project name/id, Form ID and dataset name.

We reproduced this and saw it was happening with all forms. We have a fix here: getodk/central-backend#1776
