I have DetachedCriteria object look like this.

DetachedCriteria dc = DetachedCriteria.forClass(Car.class)
.add(Restrictions.eq("isWork", true))
.add(Restrictions.eq("isRed", false))
.add(Restrictions.eq("isBlue", true))
;

Supose I want to delete one of Restriction for example the second one.
Is any way to do this automaticly?

Just create a method that takes boolean parameters, and pass the appropriate boolean parameters in, depending upon which restrictions you would like to incorporate.

I use spring and SimpleFormController.
DetachedCriteria is used in Command object. When user want to see the page in first time ( for example GET /result.htm )
my dc object have to have some default restrictions ( Im adding this in constructor of the command object and when spring load this path "he" not call any set methods, only constructor is called so this is only one place where this default restriction can be add. )
but when he GET /result.htm?param=xx&param2=yy
( so in this moment the default constructor add default restriction and call serParam, setParam2 methods )

I can pass for example GET /result.htm?addDefaultRestriction=true
or GET /result.htm?addDefaultRestriction=false&param=xx&param2=yy
and in my SimpleFormController command object

setAddDefaultRestriction(boolean b) {
this.dc.add(Restriction....);
}

but this is ugly is'nt it?
I mean this is not friendly for user to read address in browser. superhost.pl/excelentpath?andUglyDefaultParam=true
