TYPO3 Core

The wizard of the backend layout loads always the layout from the database, not the current of the textarea. So you always have to click on the save button of the record in order to adjust you layout with the wizard without loosing your latest changes in case you forgot something.

1. Create a new backend layout and click on the wizard icon.
2. E.g. create a two column layout. Click the save and close icon in the wizard window. The textarea is updated with your new layout.
3. Click on the wizard icon again. The wizard shows the default layout instead of your defined one: one undefined column.

1. Open an existing backend layout and click on the wizard icon. Your current column setting is loaded.
2. Edit your layout (remove or add columns). Click the save and close icon in the wizard window. The textarea gets updated with the new configuration.
3. Just click on the wizard icon again: The wizard shows the old setting of your columns (that are saved to the database) instead of your adjusted layout.
