Problem with selectOneMenu

[marcel.m.vielsack.cluetec.de]

Hi!

I want to use the selectOneMenu to choose a dimension out of a list and store the chosen dimension to my bean.
The values are displayed but when I choose a Item the value isn't stored into my bean.
Here's my code from the xhtml

<h:selectOneMenu id="dim" value="#{product.dimension}">

<f:selectItems value="#{ProductDetailsAction.coicopDimensions}"></f:selectItems>

<s:convertEntity />

</h:selectOneMenu>

Does anybody know how to fix it?

Thanks

Marcel

Hi Marcel,

Try this one:

<h:selectOneMenu id="dim" value="#{product.dimension}">
  <f:selectItems value="#{ProductDetailsAction.coicopDimensions}"/>
  <a4j:support event="onchange" ajaxSingle="true"/>
  <s:convertEntity />
</h:selectOneMenu>

Regards,

Thanks for your answer tamas!

Seems like your hint leads me in the right direction! - Thanks for that too ;)

But now I get an java.lang.NumberFormatException.
I think the <s:convertEntity /> - tag is the source, because when I remove it from the code there's no exception. But the return value is null again.

Do I have to create my own converter or is there an build-in converter which can handle strings?

I tested a bit and wrote my own converter. The converter just returns Strings, but seems to work fine.

I also wrote a litte javascript which promts the value of my selectOneMenu. The script works an shows the value I selected.

But the binding to the bean doesn't work. When I change the selectOneMenu to an inputText the binding works.

Has anybody an idea what's the problem?

Marcel,

I think you could just use

<s:selectItems>

if your list contains string items. I don't think you need to create a converter.

Thank you,
