6.5.5 Disabling Warn on Unsaved Changes
Query-by-example items change values by design. Disable the unsaved changes warning so users aren't confused when navigating away.
As shown below, by default APEX warns about unsaved changes when navigating to another page. This can alarm the user if they were not performing a data entry task. When using a page item for query by example, consider disabling its Warn on Unsaved Changes setting. You can configure this setting once at page level, and also set it per page item as appropriate for your use case.
