Given two xtext editors, both open at the same time. One inside the active editor part and one inside a view part (e.g. Xrepl). When the code completion is invoked from within the view part, the proposals are shown in the editor part instead of the view part. The problem is that the expression:

<extension point="org.eclipse.core.expressions.definitions">
      <definition
            id="isActiveEditorAnInstanceOfXtextEditor">
         <with
               variable="activeEditor"> <- should check for activePart
            <adapt
                  type="org.eclipse.xtext.ui.editor.XtextEditor">
            </adapt>
         </with>
      </definition>
   </extension>

checks whether the active editor is an xtext editor. In the described scenario this is always true, resulting in code completion showing only in the editor part and not in the view. This can be fixed by checking whether the active part is an XtextEditor.
