Clearing variable's values

Overview
If a variable with a value is hidden or disabled, the value is retained. Sometimes hidden or disabled variables are set through a dependency and only used in another part of the dependency. In that scenario retaining the value of a hidden or disabled variable is needed.
Other times it is desirable to erase the value of a hidden or disabled variable. That can be done in the dependency.
An example of how to erase the value of a hidden or disabled variable in a dependency
function main() {
 HideAndNull(#variable1.getControl(), #myVar1==0);
 HideAndNull(#variable2.getControl(), #myVar2==5);
}
function HideAndNull(control, condition) }
 control.show(condition);
 if (!condition) control.setValue(null);
}
