Hey!  
I have a problem with configuration of dependent dropdowns (using observerId).  
When I create document with dependent dropdowns and copy it something weird is happening. Dropdowns from copied doc observe dropdowns from original version. When I change value in dropdown then I have changes on original document also.  
I searched the forum and couldn’t find a similar problem. Is there any way to fix that?

Have you prefixed observableId / observerId with

```auto
${cluster.id}

```

as described on:

Thank u for your response @machak !  
Now I realized , I haven`t.  
But when I add it (_ **${cluster.id}** _.\<name\_id\>), fetching values to dropdown stopped working.  
Maybe because dropdowns are in different compounds?  
How to check the value of _cluster.id_ variable?
