• It seems that the switch library (as a system librarian) does not work anymore. To reproduce: 1. Switch library. 2. Reload page. 3. See that the first login library re-appear in the "switch" menu
• The loan for the same day gives a due date in the next day. Try it with this item (barcode = asdf) in library AOSTE-LYCEE. I adapted the opening hours, but even if it is still open today, the due date is set tomorrow.
• In the cipo editor
  • I cannot save the form when I enter a not integer in some fields. All fields (except "Frais") must contain only integer. A validation message should be displayed if a decimal is entered.
  • I should not be able to enter decimal with more than 2 digits after comma in the field "Frais". Otherwise, a validation message should be displayed.
    
  • I should not be able to check twice the same combination of "item type / patron type". However, it is the case, see this one and this one
  • I should be able to see the JSON description (is it normal that they are not displayed? were they displayed in ils.test.rero.ch? I cannot check since it is offline...)
• This issue is not solved: The application section of the circulation policy editor does not behave as expected. #1363

I don't think this is related to the current US. Edit: see rero/rero-ils-ui#442

It seems that the default ci-po is used. This may be an existing bug that is highlighted with this US. to be confirmed by @BadrAly Edit: this was a bug coming from the current work. The ci-po updated were not correctly indexed.

It is the original behaviour of the editor. I can make additional corrections but it will take some time. The restriction on ptty-itty combination that was not working is related to the issue above (due date).

Actually, when we uncheck the last item type, it unchecks the patron type automatically. And when the patron type is not checked, the item types are not displayed. I can change the behaviour to let the item types, but the patron type has to be unchecked manually to allow the form saving.
