**Steps to reproduce:** 1. Create/open a Domain diagram (React Flow mode). 2. Create an _Entity_ if needed. 3. Click on the _Entity_, its palette opens. 4. The tool section for attribute creation defaults to "Text" attributes. 5. Open the tool section and select "Boolean". A boolean attribute is created. 6. Re-open the entity's palette **Expected**: the "Boolean" creation tool should now be the default proposed for the tool section as it is the last one invoked. **Actual**: the default is still the "Text" attribute creation tool.
