Dynamic Form send params to server

Hi, i used Gwt-ext, are now passed to smartGwt 2.4. With gwt-ext used the method “formPanel.getForm().submit(”../login/login.do", null, Connection.POST, “Login…”, false);" with text field add to formPanel.

In the smartgwt how to pass parameters with dynamic form to server.
The my action path are set in struts-config.xml file.

Set the values (setValue) and save the form (saveData)

How to set the path of action, I use setAction but does not work
