I've got a PAGE scope DataModel which was working fine until I added an
inputText tag to the page. Now the selection is always the first one on the
list. I know I've had some trouble understanding exactly how DataModels (and
Seam in general, really) works, so I thought I'd post this here to see if
someone can educate me before I declare that there's a bug.
I've boiled my code down to isolate the problem. I have this bean:
| @Stateful
| @Scope(ScopeType.SESSION)
| @Name("foo")
| public class FooBean implements Serializable, Foo
| {
| static final long serialVersionUID = -6536629890251170098L;
|
| private static Log log = LogFactory.getLog(FooBean.class);
|
| public FooBean()
| {
| }
|
| private String text;
| public String getText()
| {
| return text;
| }
| public void setText(String text)
| {
| this.text = text;
| }
|
| @DataModel(scope=ScopeType.PAGE)
| List<String> names;
| @DataModelSelection
| private String selectedName;
|
| public String dummy()
| {
| log.debug("Selected name is " + selectedName);
| return null;
| }
|
| @Factory("names")
| public void refresh() {
| names = new LinkedList<String>();
| names.add("Fred");
| names.add("Wilma");
| names.add("Barney");
| names.add("Betty");
| }
|
| @Destroy
| @Remove
| public void destroy()
| {
| }
| }
|
and this page:
| <body>
| <h:form>
| <!-- <h:inputText value="#{foo.text}"/> -->
| <h:dataTable value="#{names}" var="name">
| <h:column>
| <f:facet name="header">
| <h:outputText value="Name" />
| </f:facet>
| <h:outputText value="#{name}" />
| </h:column>
|
| <h:column>
| <f:facet name="header">
| <h:outputText value="Action"/>
| </f:facet>
| <h:commandButton action="#{foo.dummy}" value="Test"/>
| </h:column>
| </h:dataTable>
| </h:form>
| </body>
|
It works fine unless I un-comment the inputText field, in which case the
dummy() method always reports that I selected the first name.
What am I doing wrong?
Thanks,
Joe
