[crash1989]

I have browsed the forum for this error and could not find a helpful solution.I am using MyEclipseBlue 7.5 and a SQL database.Any help would be greatful.
I use a simple database named student with two fields id and name.I use hibernate which is successfully added into the project and icefaces too.
But when I use <ice:dataTable var=”abc” value=”#{sessionbean.list}”> there is validation error and the is javax.servlet.ServletException in apache server.
I have all my doubts pinned on dataTable tag , since eclipse couldn’t resolve it and it seems to be the right way to do it.
Here is the form I use

<ice:form partialSubmit="true">

                    <ice:dataTable var="item" value="#{sessionbean.list}"  border="1">
                        <ice:column id="column1">
                            <f:facet name="header">
                                <ice:outputText value="ID" id="ID"></ice:outputText>
                                <ice:outputText value="#{item.id}"></ice:outputText>
                            </f:facet>
                        </ice:column>
                        <ice:column id="column2">
                            <f:facet name="header">
                                <ice:outputText value="Name" id="Name"></ice:outputText>
                                <ice:outputText value="#{item.name}"></ice:outputText>
                            </f:facet>
                        </ice:column>
                    </ice:dataTable>

                </ice:form>

The sessionbean class is

public class SessionBean {
    public ArrayList<Student> list= new ArrayList<Student>();
    public StudentDAO dao = new StudentDAO();
    public ArrayList<Student> getList() {
        return list;
    }

    public void setList(ArrayList<Student> list) {
        this.list = list;
    }

    public SessionBean()
    {
        list.addAll(dao.findAll());
    }
    
    public StudentDAO getDao() {
        return dao;
    }

    public void setDao(StudentDAO dao) {
        this.dao = dao;
    }
}

I figured out the error .. i included two ice:output tags in a f:facet tag , which is a duplication error.
I used a ice:panelgrid and the error was gone ..

Glad you have the problem sorted out. Thank you for letting us know.
