CDK help needed. How to create component with a4j:support fu

[david.spark]

I'm trying to create a custom component for selecting times. It consists of 2 HTML Selct menus (one for hours and one for minutes). What I want is to be able to add an a4j:support tag within the component so that it rerenders another component for the onchange event.
The problem is that when I add the a4j:support tag like so:

<my:timeSelector value="#{eventStaff.endTime}">
 <s:convertDateTime pattern="HH:mm"/>
 <a:support event="onchange" reRender="hours"/>
</my:timeSelector>

it doesn't work. When I look at the generated HTML it does not include any onChange attributes so I presume that I need to do something when creating the component... my question is what?

Anybody...?

If it isn't possible to add that functionality to custom components are there any other solution to my problem that anyone can think of?

Thanks!

Hello,

Your component should output "onchange" attribute in order for a4j:support to work properly. E.g. the following should work:

<my:timeSelector value="#{eventStaff.endTime}" onchange="alert('changed!')"/>

Ah, thanks! That's a great help.

Now all I need to do is figure out how to get my component to accept a

<s:convertDateTime pattern="HH:mm"/>

within it :-)
