Steps to reproduce:
- Create a page provider
- Configure the form and result form at View Designer
- Modify your bundle file adding auto and display-auto-control in your nuxeo-search-form tab
- Deploy your changes in your environment. The changes are deployed ok.
- Back to view designer
- Access to your search form.
- Apply some change to your search, e.g. Change the icon or the order.
- Save your changes
The bundle file is overwritten and the attribute 'auto' and 'display-auto-control' are removed.
NOTE: My suggestion: Add two checkboses in the search configuration page to set the auto search and display auto control features
