ListShuttle doesn't populate targetValue in BackingObject

[christiannockemann]

Hello Everyone,

this is my code:

JSP:

<rich:listShuttle sourceValue="#{analyseBean.catalog.catOptions}"
 targetValue="#{analyseBean.catalog.catTarget}" rowKeyVar="rkv"
 var="option" orderControlsVisible="false"
 fastOrderControlsVisible="false" listsHeight="400">
 <rich:column id="option">
 <f:facet name="header">
 <h:outputText styleClass="headerText" value="Filteroptionen" />
 </f:facet>
 <h:outputText value="#{option}" />
 </rich:column>
</rich:listShuttle>

BackingBean:

private List<String> catOptions = new ArrayList<String>();
private List<String> catTarget = new CopyOnWriteArrayList<String>();
public void setCatOptions(final List<String> catOptions) {
          this.catOptions = catOptions;
     }

public void setCatTarget(final List<String> catTarget) {
          this.catTarget = catTarget;
     }

I read that you need to override the hashCode() and equals() methods for the items in the targetValue-List but in this case i'm using Strings.

Is anything wrong with my code?

Hi Christian,

One possible reason can be that rich:listShuttle is a plain input, thus it doesn't submit changes to server automatically. Do you submit it explicitly via a4j:support or a4j: (or h:) command component?

Presence of faces messages is another thing to check. Add rich:messages component to the page and check if there are any generated.

We haf to put a <a4j:form> tag around the listShuttle (with ajaxSubmit="false") and then it worked.

Don't ask me why.
