Cross reference problem with rename element [message #1802550]

I wrote the following grammar:

Lang: blocks+=(Block)*;

Block: 'begin_block' id=BlockID
       'end_block' ref_id=[BlockID];

BlockID: name=ID;

A simple test file:

begin_block A
end_block A

begin_block A
end_block A

When I select the first A and click on rename element the IDE selects the second and the fourth A (the third A is skipped).
How can I implement rename element to only select the A element which belongs to the right block?
For example, if I select the first A I want to rename only the first and the second A (same for the second block).

how does your scoping implementation look like?

I didn't provide any scoping implementation.
I'm using the default one.

Could you point me what I need to do in order to solve that problem?

Thanks in advance!

Simply implement scoping so that the end actually references the start
If you cutler click or f3 the second end you will se it jumps to the first start
