Problem

Take a Storable with a complex member and set index for a sub-member.
For example:
Storable myStorable with complex member myMember. Assume that myMember.value is a primitve sub-member and should get a new index.
After applying index changes with applyindexchanges the Storable Property view does not show "Index=true" althought one can verify with

show indexes from myMember; 

that the index is actually set.

Expectation

Storable Property should show "Index=true" for complex storable member with set index.

Notice

This problem does not occur when indexing a simple member.
