I have a repository plugin that uses an external web interface to search for resources in Gooru. However, there was a problem wherein the right panel (where the interface is located) went blank once I canceled the file to be added. This scenario also happens in an existing repository plugin called Geogebra. How can I fix this issue so that it won't disappear?
1. Search.
2. Select item, then click cancel.
3. Listing area went blank after cancelling.
