UFClientAction example

[RafaelOliveira]

I'm having some difficulty to understand UFClientAction, so I'd like to know if would be possible to include a simple example in this repo, maybe seting up a validation in the form.

there is already some code that verify if the name come in blank, maybe the client validation could just limit the size of the name.

We are working on the sample docs. For the time being, you find some usage example here
