Javascript error in v3.6 pro version applyButtonText

Using a clist in an edit cell, line 4135 of dhtmlxtreegrid_pro.js causes an error because mygrid is undefined. I had to change:

value=’"+(mygrid.applyButtonText||“Apply”)+"’

to:

value=’"+(this.applyButtonText||“Apply”)+"’

What API call would I use to set the applyButtonText since this looks like a really useful feature?

By the way, I absolutely love this product!

Thank for the note.
The issue is confirmed. “mygrid” replaced with “this”.
