Autocomplete does not work in XML files in particular hierarchy

Question

In particular XML nodes hierarchy eg. DrawerLayout->RelativeLayout->ImageButton autocomplete does not work as expected. Suggestion list contains invalid items. Eg. android:src is not shown inside ImageButton while it should be.

Invalid proposals:

On the other hand if hierarchy is RelativeLayout->RelativeLayout->ImageButton then everything is OK.

Valid proposals:

I've already tried:

• reopening XML file - no effect
• reopening project - no effect
• restarting eclipse - no effect

Answer 1

If inner RelativeLayout is moved to another XML file and included via <include layout="@layout/inner"/> then autocomplete is working. But it is a dirty workaround, not a real solution. So I am not accepting this answer.
