Async Command - URL Parameters

Whenever a press a Async Command button the URL parameters are lost, why?

In my page it refreshes depending on URL parameters. However when I press the button the URL parameters change to null and my page can not be well refreshed.

This is the normal behavior of the Async Command Button?


The Async Command was called by JavaScript using the go method without parameters so that’s why it looses the parameters.

The solution is to add the parameters in the go method
