The definition of the immediate check box in User Actions is:

Immediate Change this value if you'd like the action to be executed without validating the enclosing form.

I've found: If the immediate box is checked in a user action. Data is entered on the screen (using boolean data and the Nuxeo supplied boolean radio button widget) and the button linked to the user action is pushed calling a custom action bean; the entered data is not available to the custom action chain bean (a null value for the boolean is found). The custom action bean is generated by the Nuxeo IDE.

Is this correct operation? Does bypassing validation mean also bypassing data entry?
