Custom extension displayed multiple times in the Toolbox


Does your custom SmartEditor extension appear multiple times in the Toolbox? We know about this issue and prepared a quick solution for you!

When adding a custom extension to SmartEditor, removing it then adding it again, the Toolbox panel will sometimes display the custom extension doubled. The same custom extension will be displayed by the Toolbox panel multiple times, once for each time, it was added. The issue may appear due to the fact that the file driving the Toolbox panel, is not updated each time a custom extension is added or removed using the Extension Manager.

The work-around for this issue is to manually trigger the Toolbox refresh by opening the Customize Toolbox panel.

This example will fix the issue described and shown in the above picture.
