Description: I created a form using wizard. I opened the form for editing. I selected a text box and then used the popup menu item 'Replace with' to change the text box to a List Box. From that point onwards, any edit I tried to make to the box results in the app hanging. For example, I tried to turn on the Dropdown property. Manually adding a List Box to the form works normally. Steps to Reproduce: 1.Create a form with a text box and open the form for editing. 2.Use the menu item 'Replace with' to change the text box to a List Box. 3.Change the list box property 'Dropdown' setting from No to Yes. Actual Results: LibreOffice Base hangs. Expected Results: The List Box should be displayed with a triangle on its right edge that opens a dropdown menu when you select it. Reproducible: Always User Profile Reset: No Additional Info: This feature worked with the previous version of LibreOffice.
I see this with a HSQLDB when I try and edit the content of the list box, for example, to switch to a SQL-generated list. Attaching spindump and sampling profiles generated by the macOS system monitor tool. It looks like there's improper handling of a mutex lock or a wait condition.
