Hi all,

when working with a polar chart, I am able to bind all vars subclassing the Ext.Panel correctly. When trying to bind (as stated in the docs) for example rotation, clockwise, donut or other pie depending vars, I always get the well known message : this[binding._config.names.set] is not a function... Very annoying. Why are these vars stated as bindable vars accepting values from a viewModel but always throw these errors ? By the way polar chart is accepting the colors array, but if i tell it to use red and green, it transforms my input to green and blue? For customers like us extensively using the ViewModel binding (working perfectly in all classic environmental approaches) it sounds like a bad joke... What are we doing wrong here?
