OrientDB：分布式模式下的UPDATE查询结果

Question

I have a scheme-less class in my OrientDB, let's say it called 'testClass', it's pretty simple and contains 1 boolean property:

{
    lock : 'true'
}

When I execute update query via console or web ui:

update testClass set lock = true

i've got

Updated record(s) '1' in 0.033000 sec(s).

from console and similar result from web ui.

The same result i've got when I execute following Java code

ODatabaseDocumentTx db = ... // open db connection
Object result = db.command(new OCommandSQL("update testClass set lock = true")).execute()

The 'result' variable is of type Integer and contains number of updated record.

But everything changes when the OrientDB server is started in distributed mode (I have 3 nodes). The execution of the same query from console produceds:

Updated record(s) '[null]' in 0.010000 sec(s).

As you can see, now the result is an array and it's empty. The same I've got from Java - the 'result' variable is of type ArrayList and it's empty. The most interesting result shows web ui - when I execute the same query, I've got '[1]' in 'value' column, which means, I guess, that result is array and it contain 1 integer value '1'.

Is it a feature or a bug? What am I doing wrong?
