PR# 19646 VTCT error, unknown class; class text is open and listed in Groups pane
Problem Report Summary
Synopsis: VTCT error, unknown class; class text is open and listed in Groups pane
Gobo class DS_AVL_TREE is open in an editor tab, and is displayed in the Groups pane, listed under gobo_structure/structure/table/DS_AVL_TREE. Compilation has failed, having just added a local declaration for a reference to the class: Error code: VTCT Error: type is based on unknown class.

I will try to reproduce from a newly created project [this one has been in progress for a few weeks ...]
