Re: back button problem with cForm groups

[Archie Cowan]

Use this kind of logic in your flow script.

var finished = false;
    while(!finished) {
        try {
            form.showForm( mypipline );
            form.save(initialObject);
            finished = true;           
        } catch(e) {
            if(e instanceof Packages.java.lang.IllegalStateException) {
                form.lookupWidget("messages").addMessage(
                    "A server side session state error has been detected. Please do not use the back button.");
            } else {
                throw e;
            }
        }
    }

You will need to add a "messages" widget to your form model for the messages to show up.

<fd:messages id="messages">
            <fd:datatype base="string"/>
</fd:messages>

And template:

<ft:widget id="messages"/>

Hi,

 

We made a multipage cforms wizard. For the multiple pages we use groups which are activated and deactivated when a user clicks a previous/next button.

This works fine except that when users use the browsers "back" button and click on a button of a client-sided cached page. (BTW this only happens when the user uses the browsers "back" button and switches from group, within a group things keep working fine). Has anyone faced this problem before and found a solution?

 

Thank you,

Marcel
