Even though the zul.xsd shows biglistbox as a new component, neither the content assist nor the ZUL Palette show the new components as being available.

I have tried a) clearing xsd cache, b) copying the xsd to a new server and pointing the XML Catalog to that site, c) using the local zul.xsd in zkee-bin-6.0.1, d) creating an entirely new workspace on two separate computers. In all cases, biglistbox doesn't show as an available component. And, yes, I have also gone into Project preferences for ZK Visual Editor and ensured that it is tied to the zkee-bin-6.0.1.
