11g Select outcome

Question

I'm not sure if this is actually an ADF question but here goes:
I want to select an outcome value from a drop down list instead of having lots of buttons. My normal 'outcome' button looks like this:
<af:commandToolbarButton actionListener="#{invokeActionBean.setOperation}"
text="OUTCOME1"
action="#{invokeActionBean.invokeOperation}"
id="ctb1" ... >
<f:attribute name="DC_OPERATION_BINDING"
value="bindings.OUTCOME1"/>
</af:commandToolbarButton>
So I create a 'select-one' list of outcomes and bind the value to 'select_outcome'. I have a 'Go' button next to the select that will be used to submit the form, and I want to use the value of 'select_outcome' as the attribute value i.e. the method binding for the 'Go' button
<af:commandToolbarButton actionListener="#{invokeActionBean.setOperation}"
text="Go"
action="#{invokeActionBean.invokeOperation}"
id="ctb2" ... >
<f:attribute name="DC_OPERATION_BINDING"
value="??????"/>
</af:commandToolbarButton>
Can anyone explain how I use the select value as the operation binding or otherwise explain how to present activity outcomes as a select-one list?

Answer 1

ok, can't workout how to do it that way so I'm doing it in a managed bean using:
taskService.updateTaskOutcome(wfContext, task, outcome);
I'm unsure what to sent back to the client though, some script to close the window?
