I would like to customize Advanced Search to adding "My Search" option. I changed share-config-custom.xml (see below). But my customization doesn't work. I added a new item to search menu, but i get error "Form definition could not be found".
I use the definition from cm:folder, but it doesn't work. I use community edition 7.3 in Docker desktop.
I try to create new advanced search more than 10 day. I had a namespece prefix. If I use namespace prefix "myprefix:customContentModel" I get error "Namespace prefix myprefix is not mapped to a namespace URI".
Wow.... What does is mean? Where is defined namespace URI?
