rich:inputNumberSpinner in a table

[neilac333]

I am using the rich:inputNumberSpinner inside a table of Widget objects on an order form to represent the quantity of widgets desired. Also on the form are the total for each widget (quantity * price) and the total for the entire order.

As you might suspect, I need to have those totals updated instantaneously when the spinner is updated. The problem is that if I try to use a valueChangeListener method, I don't have access to the individual widget whose quantity was updated (because the sole parameter is the ValueChangeEvent object). I have considered ugly hacks like naming my spinners in a clever way and using that information in my Java code, but that is so lame.

Any insight into how I can accomplish this in a more elegant way?

Thanks.

please paste current code snippet.

Thanks, Ilya, but I figured it out. It was simply a matter of using a4j:support, which I thought only applied to standard JSF components.

Hi,

could you please post your solution.
I've got a similar problem an just can't find how to use a4j:support correctly.

Would be nice if you could help me :)

<rich:dataTable value="#{actSoStory.soStoryAdvancedList}" var="ssa3">
<rich:column>
<rich:inputNumberSpinner value="#ssa3.saPageNumber}">
<a4j:support action="updateSsaPageNum" reRender="#{flowRenderFragments}" event="onchange"/>
</rich:inputNumberSpinner>
</rich:column>
</rich:dataTable>

Question is, how to access "ssa3"?
Normaly I would use something like:

<f:setPropertyActionListener value="#{ssa3}" target="#{StoryBB.storyAdvancedSelectedRow}" />

But it is not possible to set f:setPropertyActionListener within the inputNumberSpinner.

...so I just want to update (via ajax) ssa3 when pageNum is changed by the numberSpinner.

Would be great if you or someone else could help me :)

Bests,

Jan

But it's possible to define it inside support ;)

Ahh... yeah :)
It's working this way !
Thanks a lot ;)
