I've post another topic in title of action and my problem was that i could not pass parameter to an action,
after a while that problem was solved but the only way to passing parameter to client's action is from command line,
I can't pass any value to client's action via NetXMS console.

Additional information:

The action is listed in client's valid action,
the action can be execute from NetXMS console,
passing parameter to client's action is ok with server side command line.
