SeamSelectItemsNewDesign Problem with converting
hi petemuir,
i found your project "SeamSelectItemsNewDesign", i tryed to use it, download selectitems-1.1.1beta4.
than i put selectitems.jar and selectitems-ui.jar into my WEB-INF/lib.
then i tryed to fill application combo with application name
Application class is simple database entity bean has properties applicId,name,code,description
then i wrote entity query into my componets.xml file
<framework:entity-query name="applications" ejbql="select a from Application a" />
and then i wrote simple converter class
@Name("exampleBean")
public class ExampleBean extends SelectItemsConverter {
@Override
protected String convertToString(FacesContext facesContext, UIComponent uIComponent, Object object) throws ConverterException {
return ":::";
}
@Override
protected Object convertToObject(FacesContext facesContext, UIComponent uIComponent, String string) throws ConverterException {
return new Application();
}
}
and in the end into my facelet i wrote this :
<h:selectOneMenu styleClass="font_style" value="#{application.name}" converter="#{exampleBean}">
<si:selectItems value="#{applications.resultList}" var="application" label="#{application.name}" />
</h:selectOneMenu>
<h:messages style="color: red" for="application"/>
i found discussion about this problem
http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4001066#4001066
you said :
The first issue I suspect is a class loading problem - you probably have multiple (stale) copies of the selectitems.jar floating around.
i'm sure that i had only one selectitems.jar and selectitems-ui.jar into my ear file
which contains war file, such contains this files into web-inf/lib folder
i also read this and done everything
http://wiki.jboss.org/wiki/Wiki.jsp?page=SeamEntityConverter
but i got an error again and again :(
javax.faces.FacesException: Converter must implement SelectItemsConverter: com.magticom.billing.businesslayer.sessionbeans.ccare.ExampleBean@1c2832e at org.jboss.seam.selectitems.ui.UISeamSelectItems.addConverters(UISeamSelectItems.java:364) at org.jboss.seam.selectitems.ui.UISeamSelectItems.getValue(UISeamSelectItems.java:246) at org.apache.myfaces.shared_impl.util.SelectItemsIterator.hasNext(SelectItemsIterator.java:102) at org.apache.myfaces.shared_impl.renderkit.RendererUtils.internalGetSelectItemList(RendererUtils.java:477)
what did i wrong ? i did not changed entitymanager and i think i must not add any config into my components.xml

Paata.
