Custom Buttons in scheduler

Is there a trick to getting the custom button section working as described here:



dhtmlx.com/dhxdocs/doku.php? … ion_header



I’ve added the button:“help” piece and the label as:



scheduler.locale.labels.button_help=“Help label”;



All I get is a button with the word “undefined”



Actually this is a bug in current version.
You can
a) update js files with attached one
or
b) use section name instead of button name for locale
{name:“description”, height:130, map_to:“text”, type:“textarea” , focus:true, button:“help”}
scheduler.locale.labels.button_description=“Help label”;
