Thank you for your post.
All the issues you are faced with is the result of our changes related to the Code Assistance functionality.
We have changed the way of TWS parser work.
When you open your project, the TWS parser begins to analyze the project code. There is some place in your code that the parser couldn't handle. It stops at this place and doesn't go further. This is the reason that the mentioned by you options don't work in the files that were not analyzed.
The same reason is actual for the additional bugs. The tests and tests methods are not analyzed and not recognized in your code.
Our developers are looking for the cases of the code which lead to such behavior, but this can be the specification of the custom code.
Anyway, the issue will be solved in the nearest versions of the IDE.
The file where the parser cannot handle some step will not have the Code Completion functionality, but all other files will have.
We will appreciate your feedback after these changes will be released.
