ColdFusion Tag is not supported

Question

I am new to ColdFusion and downloaded the latest version of Railo which is compatible with ColdFusion 10.

I want to use the CFGrid and CFWebsocket tags which are included in Adobe's ColdFusion 10`, as you can see in the documentation.

But when I start my application, an error says that these tags are not supported.

Answer 1

Railo 4.2 is roughly compatible with CF10, but there are some things it doesn't support, among them cfgrid and cfwebsocket.
