ListShuttle Illegal Argument Exception

[dhook]

I am getting the following exception:

09:18:01,156 SEVERE [viewhandler] Error Rendering View[/BackTestEdit.xhtml]
java.lang.IllegalArgumentException
at org.richfaces.component.UIOrderingBaseComponent.createDataModel(UIOrderingBaseComponent.java:193)
at org.richfaces.component.UIListShuttle.createDataModel(UIListShuttle.java:358)
at org.ajax4jsf.component.UIDataAdaptor.getExtendedDataModel(UIDataAdaptor.java:621)
at org.ajax4jsf.component.UIDataAdaptor.walk(UIDataAdaptor.java:1151)

Here is my list shuttle Code:

<rich:listShuttle sourceValue="#{entryTriggerList}"
targetValue="#{backTestHome.entryTriggers}" var="trigger" listHeight="300"
listWidth="300" sourceCaptionLabel="Available Entry Triggers"
converter="#{entryTriggerConverter}"
targetCaptionLabel="Selected Entry Triggers">
<rich:column>
<h:outputText value="#{trigger.entryTriggerName}"></h:outputText>
</rich:column>
</rich:listShuttle>

Here is the converter:

public class EntryTriggerConverter implements Converter {

@Override
public Object getAsObject(FacesContext context, UIComponent component,
String value) {
System.out.println("getAsObject executed...");
System.out.println("Value has this " + value);
//int index = value.indexOf(':');
//return new EntryTrigger(value.substring(0, index), value.substring(index + 1));
return new EntryTrigger();
}

@Override
public String getAsString(FacesContext context, UIComponent component,
Object value) {
System.out.println("getAsString executed...");
System.out.println("Value has this " + value.toString());
EntryTrigger entryTrigger = (EntryTrigger) value;
return entryTrigger.getEntryTriggerName();
}
}


Thanks for your help!

show your model code also.

Here is the model code. Thanks for your insight!

I mean where this list defined? sourceValue="#{entryTriggerList}"

[dhook]

here is the definition.

@Name("backTestHome")
public class BackTestHome extends EntityHome {

// DDH added
private List entryTriggers = new ArrayList();
private List exitTriggers = new ArrayList();

/**
* @return the entryTriggers
*/
public List getEntryTriggers() {
return entryTriggers;
}

I had put an @DataModel before the definition, but that did not help.

[ilya_shaikovsky]

should be sourceValue="#{backTestHome.entryTriggerList}"

[dhook]

This is what I have been using the entityQuery as the source:

import com.ddh.model.*;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.framework.EntityQuery;
import java.util.Arrays;

@Name("entryTriggerList")
public class EntryTriggerList extends EntityQuery {

private static final String EJBQL = "select entryTrigger from EntryTrigger entryTrigger";

private static final String[] RESTRICTIONS = {
"lower(entryTrigger.entryTriggerClassName) like concat(lower(#{entryTriggerList.entryTrigger.entryTriggerClassName}),'%')",
"lower(entryTrigger.entryTriggerDescription) like concat(lower(#{entryTriggerList.entryTrigger.entryTriggerDescription}),'%')",
"lower(entryTrigger.entryTriggerName) like concat(lower(#{entryTriggerList.entryTrigger.entryTriggerName}),'%')",};

private EntryTrigger entryTrigger = new EntryTrigger();

public EntryTriggerList() {
setEjbql(EJBQL);
setRestrictionExpressionStrings(Arrays.asList(RESTRICTIONS));
setMaxResults(25);
}

public EntryTrigger getEntryTrigger() {
return entryTrigger;
}
}


I was thinking that the entryTriggerList would be instantiated since it was the source value... but maybe not....
