I want to provide a custom Expression editor, but as soon as I add additional elements code completion is not as expected. My editor looks as follows:
But then code completion looks as follows (i.e., code completion works only for the current type and node substitution is not available anymore).
As soon as I select all elements of the current expression's editor I get the menu. However, typing and code completion is not possible/available. The situation gets even worse as soon as the editor gets more complex.
So am I missing something? Is it possible to solve the issue or is it a bug?
