Created attachment 147813 [details] Open the form and have a look to both listboxes - one offers NULL, the other not. If you create list boxes in forms the first row in list boxes will be empty for setting NULL to the field of the data source of the form. You could switch this behaviour when setting "Entry required" while editing the table. You can't set this by setting "Input required" in the properties of the list box. The setting of "Input required" is completely ignored while creating the list. See the attached image and the attached database. Open the form of the database. List boxes for "Transfer from" and "Transfer to" are both set to "Input required" > 'Yes'. For "Transfer from" the field is set in the table to "Entry required". First List box doesn't offer NULL, second list box does. Expected behaviour: Both list boxes shouldn't offer NULL, because input is set to "required".
Created attachment 147814 [details] Screenshot of both listboxes (without and with NULL for input)
Using Ubuntu 18.04.1 (AMD64) and LO 6.2.1 RC1 Confirmed that controls ignore the setting "Input required" available in the GUI - rather the property of the attached data field determines whether a NULL entry will be made available in the list control. Have changed the version back to 5.4.7, though I believe it is actually inherited from OpenOffice.org days. I did not select that however as it appears HSQL based files, created with the latest LO are no longer fully backward compatible with Apache OpenOffice (not with 4.1.6 at least). Not everything is broken but list boxes seem to be.
Dear Robert Großkopf, To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year. There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present. If you have time, please do the following: Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/ If the bug is present, please leave a comment that includes the information from Help - About LibreOffice. If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice. Please DO NOT Update the version field Reply via email (please reply directly on the bug tracker) Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not appropriate in this case) If you want to do more to help you can test to see if your issue is a REGRESSION. To do so: 1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/ 2. Test your bug 3. Leave a comment with your results. 4a. If the bug was present with 3.3 - set version to 'inherited from OOo'; 4b. If the bug was not present in 3.3 - add 'regression' to keyword Feel free to come ask questions or to say hello in our QA chat: https://kiwiirc.com/nextclient/irc.freenode.net/#libreoffice-qa Thank you for helping us make LibreOffice even better for everyone!
