That's very disconcerting; this could be a recently introduced
bug (I redid the implementation of the shuttle renderers). I'll
have to build up a little testcase and see what's what. You're
using a recent build, right?

I tried three iterations...<tr:selectManyListbox>,<tr:selectManyShuttle> and

The single tag is the only thing that changed. The pertinent source is as
follows:
In the jsp...
<tr:selectManyListbox value="#{backing_EditDiagnosis.pickedItems}">
<f:selectItems value="#{applicationParams.diagnoses}"/>
</tr:selectManyListbox>
<tr:commandButton text="OK"
action="#{backing_EditDiagnosis.submitForm}"/>
In the backing bean backing_EditDiagnosis...
private List<Diagnosis> pickedItems = new ArrayList<Diagnosis>();
public String submitForm() {
System.out.println(pickedItems);
AdfFacesContext.getCurrentInstance().returnFromDialog(null, null);
return null;
}
In the application-scope bean...
private List<SelectItem> diagnoses;
...
diagnoses = new ArrayList<SelectItem>();
for( Diagnosis dg : d ) {
diagnoses.add(new SelectItem(dg,dg.getDescription()));
}
The <tr:selectManyListbox> control works as expected.
In the <tr:selectManyShuttle> pickedItems "becomes" an array of
java.lang.Integer's.
In the <tr:selectOrderShuttle> pickedItems is a java.util.List of size()=0.
I am REALLY baffled. The <tr:selectManyShuttle> especially seems to violate
type safety, as the backing bean very clearly types pickedItems as an
ArrayList<Diagnosis>(). Diagnosis inherits directly from java.lang.Object.
Any thoughts would be helpful.

Scott
