how to use selectmanycheckbox

[seamkaruna]

hi there,

I'm new to seam so plz help me how to use selectmanycheck with database data (store and retrieve values).

thanks,

[jamesjmp]

Hi, this is an example

<s:decorate id="orderTypeField" template="layout/edit.xhtml" >
                <ui:define name="label">#{messages['Order.type']}</ui:define>
                    <h:selectManyCheckbox id="manyCheckbox" 
                                    label="#{messages['Order.type']}"
                                     value="#{myBean.orderTypes}"
                                     required="true">
                                     <f:converter converterId="project.myTypeConverter"/>
                        <f:selectItems value="#{factoryItems}" var="orderType"
                            label="#{orderType.description}"/>
                    </h:selectManyCheckbox >
                </s:decorate>

factoryItems is a factory component that has a simple HQL query to database that gets all elements to be displayed.
The use of convertes depends on what you are using.

hi jaime,

  thanks for ur reply but i'm very new to this framework so please post any simple sample codes with backingbeans(step by step explination) and my prob is to store value in the database. plz post me some useful codes.

thanks,

[jamesjmp]

I´m so sorry but I´m very busy right now to provide you with a step by step explanation. I´ll do it later if I´ve time
Hope this links: link and link 2
would be useful for you.
actories are explaind in seam reference and there you may find some explained examples.

<h:selectManyCheckbox id="rights"
value="#{accessrightsHome.instance.id.accesscontrol}"
layout="lineDirection" border="1">
<f:selectItem id="item1" itemLabel="Read" itemValue="1"/>
<f:selectItem id="item2" itemLabel="Write" itemValue="2"/>

plz help me and thanks in advance.

If I where you I would use a List<String accesscontrol;
Your error is

<h:selectManyCheckbox id="rights"
value="#{accessrightsHome.instance.id.accesscontrol}"

Should be

<h:selectManyCheckbox id="rights"
value="#{accessrightsHome.instance.accesscontrol}"

hi servin,

when i use List<string> i'm getting this following error,

persistence.unit:unitName=acm.ear/acm.jar#acm -> org.hibernate.MappingException: Could not determine type for: java.util.List, at table: accessrights, for columns: [org.hibernate.mapping.Column(accesscontrol)]

and the accesscontrol field in database is varchar. I cannot use this <h:selectManyCheckbox id="rights"
value="#{accessrightsHome.instance.accesscontrol}" because it is the bean path for accesscontrol field(i didnt create primary key in that table), plz help me in this issue.

thanks

[jamesjmp]

hi,
please paste the error you have trying it the original way.
By the way how have you defined accessrightsHome, paste attributes of the class at least.

[seamkaruna]

package com.acm.session;

import com.acm.entity.*;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.framework.EntityHome;

@Name("accessrightsHome")
public class AccessrightsHome extends EntityHome<Accessrights>
{


    public void setAccessrightsId(AccessrightsId id)
    {
        setId(id);
    }

    public AccessrightsId getAccessrightsId()
    {
        return (AccessrightsId) getId();
    }

    public AccessrightsHome()
    {
        setAccessrightsId( new AccessrightsId() );
    }

    @Override
    public boolean isIdDefined()
    {
        if ( getAccessrightsId().getDeptname()==null || "".equals( getAccessrightsId().getDeptname() ) ) return false;
        if ( getAccessrightsId().getRolename()==null || "".equals( getAccessrightsId().getRolename() ) ) return false;
        if ( getAccessrightsId().getAccesscontrol()==null || "".equals( getAccessrightsId().getAccesscontrol() ) ) return false;
        return true;
    }

    @Override
    protected Accessrights createInstance()
    {
        Accessrights accessrights = new Accessrights();
        accessrights.setId( new AccessrightsId() );
        return accessrights;
    }

    public void wire()
    {
        getInstance();
    }

    public boolean isWired()
    {
        return true;
    }

    public Accessrights getDefinedInstance()
    {
        return isIdDefined() ? getInstance() : null;
    }


}

this is the error i am getting.

[jamesjmp]

Hi, I provide you with an example

                <h:outputText value="TODOS"/>
                    <h:selectManyCheckbox id="manyCheckbox" 
                                    label="#{messages['Order.type']}"
                                     value="#{settlementInstructionDomesticBean.orderTypes}"
                                     class="selectStyle" 
                                     required="true">
                        <f:selectItems value="#{orderDomesticObjItems}" var="orderType"
                            label="#{orderType.description}"/>
/>                            
                    </h:selectManyCheckbox >

and this is the factory:

    @Factory("orderDomesticObjItems")
    public List<SelectItem> getOrderDomesticObjItems() {

        List<SelectItem> items = new ArrayList<SelectItem>();

        for (OrderType st : this.getOrderByMarket()) {

            SelectItem item = new SelectItem();
            item.setValue(st);
            item.setLabel(st.getDescription());

            items.add(item);

        }

        return items;
    }

    public List<OrderType> getOrderByMarket() {
        Query query=em.createQuery("FROM OrderType AS type");
        return query.getResultList();
    }

[seamkaruna]

hi,
after using above code i'm getting this following error,

java.lang.IllegalArgumentException: Expected a child component type of UISelectItem/UISelectItems for component type javax.faces.SelectMany(rights).  Found null.

[seamkaruna]

<h:selectManyCheckbox id="rights" value="#      {accessrightsHome.instance.id.accesscontrol}"
  layout="lineDirection" border="1">
  <f:selectItems value="#{rights}" label="#{rightstb.right}"/>
</h:selectManyCheckbox>


public List<Rightstb> getRightsparam() {
          String ejb = EJBQL;
          System.out.println(getEntityManager().createQuery(ejb).getResultList()
                    .size());
          return getEntityManager().createQuery(ejb).getResultList();
     }
     @Factory("Rights")
     public List<SelectItem> getRights()
     {
          List<SelectItem> results = new ArrayList<SelectItem>();
          for (Rightstb obj : this.getRightsparam())
          {
          SelectItem item = new SelectItem();
        item.setValue(obj.getRights());
        item.setLabel(obj.getRights());

        results.add(item);
          }
          return results;
     }

hi my problem is in storing the selectmanycheckbox value into the database.

[jamesjmp]

does your problem go on?
Maybe it´s due to a type conversion feature. Try adding a converter:

  <s:convertEntity/>

And if it doesn´t work with a custom converter

 <f:converter converterId="project.myTypeConverter"/>

If you need an example of a custom converter let me know.
