T5: form context not invoking onActivate with matching parameters

[Ben Tomasini <be...@gmail.com>]

I was using the following code:

Start.html
<t:form context="literal:test">
    <t:submit />
</t:form>

Start.java

    void onActivate() {
        System.out.println("No args");
    }

    void onActivate(String value) {
        System.out.println("String arg");
    }

On a form submit,  the console shows:

No args

I expected the form tag above to invoke the onActivate method with matching
arguments, it only invokes the noargs method.  Is this a bug, by design, or
am I missing something?

Now that I read the manual I see that all I needed to track the id was this:

    BigDecimal id = null;

    void onActivate(BigDecimal id) {
        this.id = id;
    }

    BigDecimal onPassivate() {
        return id;
    }

Very elegant... Thank you, Tapestry!

Re: T5: form context not invoking onActivate with matching parameters

There's two different contexts here: the page's activate context
(produced by the "passivate" event, provided to the "activate" event
and the Form component's context, which is provide to event handler
methods related to the Form ("success", "prepare", etc.).

The Form does not fire an "activate" event; the framework fires the
"activate" event, on the page (not the Form), passing the page's
activation context.
