The Taxonomy picker dialog has two types, a tree to pick from (the default). But there is also a Palette type. If that is used, not all taxonomy terms are loaded into the palette.
In the taxonomy demo:
- select in an about document the key "Transport_and_infrastructure"
- save the document
on /hippo:namespaces/hippotaxonomy/classifiable/editor:templates/default/root add a String property "taxonomy.type" with value "palette"
edit the document again and open the pickerresult: the key from the document is not in the list on the left neither is it showing up on the right. When selecting another key, the original key (Transport_and_infrastructure) is removed from the document!
Building up the list of terms for the Palette type seems to omit some of the terms.
