Nifty – controlDefinition [nifty-tabs] missing

I had some problems with nifty-tabs in my game. I found that it should be fixed in later version of nifty. So I downloaded new version of jME3 from and copied nifty .jars from zip file to jmonkeyplatform/libs. Now when I try to run game, tabs doesn’t show up and I give these warnings:
WARNING: controlDefinition [nifty-tabs] missing.
WARNING: controlDefinition [nifty-tab] missing.

Can you please tell me what did I wrong?


Ok, so in later nifty GUI “nifty-tabs” is named “tabsGroup” and “nifty-tab” is named “tab”.
Maybe someone will have same problem so this is solution
