Thanks for getting back so quick.

>>>Do you define any beans in your CustomSubmit component?<<<

Not quite sure what you mean here, below is an extract from the page
specification

<page-specification class="com.afs.exampleapp.pages.AFSHomePage">
    
    <bean name="togglerDataBean"
class="com.afs.exampleapp.beans.AFSTogglerBean" lifecycle="request">
        <set-property name="overrunCount" expression="'3'"/>
    </bean>

    <component id="linkToHome" type="PageLink">
        <static-binding name="page">Home</static-binding>
    </component>

    <component id="togglerCreateForm" type="Form"/>

    <component id="createSubmit" type="CreateUserProcessSubmit">
        <static-binding name="label">Create</static-binding>
        <!--<static-binding
name="processDataBeanName">togglerDataBean</static-binding>-->
        <static-binding name="processDataBeanName">toggler</static-binding>
        <static-binding name="processId">toggler</static-binding>
        <static-binding name="processInstanceId">A</static-binding>
    </component>

....

>>>
Why don't you create a bean that implements IActionListener
<<<


The idea is that this is a very self contained component which forms a
bridge between tapestry and a configurable state based process engine. As
such we simply specify a parameter indicating the process to kick off, a
parameter indicating the instance of the process and pass in a bean for the
process to retrieve and set data. Another custom submit button will take the
instance parameter and an event id etc to fire in. Given that
AbstractComponent sports a getBeans method it did not seem necessary to
create a separate bean to do this. 

It occurs to me that I could always pass the bean (togglerDataBean for
example) directly into processDataBeanName if I change it to Object type and
use OGNL.

It would still be interesting to know however why getBeans returns an empty
collection.

>>>
getContainer().getBeans()
<<<

Yup, however this returns IComponent which does not surface getBeans().
Maybe I'm just not reading the JavaDoc correctly with my dislexic eyes :-|


Thanks

Do you define any beans in your CustomSubmit component?

Perhaps you want to invoke getContainer().getBeans().

Why don't you create a bean that implements IActionListener and just set
that as the listener for
the existing Submit component?

Do you have any <bean> elements in CreateUserProcessSubmit.jwc?

Sounds like you want to access beans from the container, the page that references
CreateUserProcessSubmit.
