Hi,

Using Cocoon 2.1.4-dev.

my attempt to write a wizard style sequence in Woody is (roughly) as below. Can anyone confirm I'm on the right track, or if I'll get performance problems later, for instance?

function mywizard{

var f1 = form.load("form1_model.xml");
var f2 = form.load("form2_model.xml");
var f3 = form.load("form3_model.xml");
var step=1;

while(step){

	switch(step){

                case 1:
                        f1.showForm;
                        step=2;
                case 2:
                        f2.showForm;
                        if (submitId = previous){
                                step=1;
                        }else{
                                step=3;
                        }
                case 3:
                        f3.showForm;
                        if (submitId = previous){
                                step=2;
                        }else{
                                step=null;
                                cocoon.sendPage("success");
                        }
	}

}	

}
 

Approach is correct - js is wrong (e.g. should be submitId == 
"previous"), but I think you know that.

Problem: from success page, if user hits Back button on browser, the continuation is still alive. How can I fix this?
Qu: I've noticed elsewhere syntax such as 

var k = form.showForm...
k.invalidate();
 

Invalidate prevents the user from going back to that continuation with 
the back button. Thing to note is that a reference to each object is 
stored in the continuation, not the object. So if someone changes the 
content of an object (e.g. a form), then goes back, they'll see the new 
content, not the old.

Make sense?

what exactly does this do?

TIA for any help
