Checkbox inside a:richList

[cybermakoki]

Hi all,

I'm desperate, i can't put a checkbox inside alfresco tag richlist, this is my code:

<h:selectBooleanCheckbox id="col19-check" value="#{r['dm:selected']}" />

I'm getting all the time this error:  Base is null: r

It's possible that this could be a bug?

Need help please

<h:selectBooleanCheckbox id="col19-check" value="#{r.selected}" />

In Browsebean  add property evaluator for selected and implement how to calculate value for this and that is that.

[cybermakoki]

Yes, but i can't modify BrowseBean.java …

[savic_prvoslav]

well you override it with class thatextent thath bean

[cybermakoki]

I've tried that and doesn't works… it only works if you render the content with a h:dataTable

Thank you for your reply, but I don't understand this:

getWindowsView() {

//for each node that is returned add this.
cont.get(i).addPropertyResolver("selected", resolover );

}

I don't know how to use "getWindowsView()" method and I don't know how does the NodePropertyResolver works…

Can you help a bit more please?

[savic_prvoslav]

public List<Node> getNodes();
public List<Node> getContent();

override this two methods like this

public List<Node> getNodes()
{
List<Node> list= super.getNodes();
for(int i=0;i<list.size();i++)
{
list.get(i).addpropres..("selected",resolover );
}
}

public NodePropertyResolver resolover = new NodePropertyResolver() {

   /**
    * 
    */
   private static final long serialVersionUID = 903502146868126457L;

   @Override
   public Object get(Node node) {

   CHECK YOUR MODEL TO SEE IF NODE IS SELECTED OR NOT.
   }
    };‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

ps: This is more then enough to fix your problem. have fun.

hi again..

I've tried your code but I'm getting NullPointerException

this is de custombean:

package es.sic.beans;

import java.util.List;

import org.alfresco.service.cmr.repository.datatype.DefaultTypeConverter;
import org.alfresco.service.namespace.QName;
import org.alfresco.web.bean.BrowseBean;
import org.alfresco.web.bean.repository.Node;
import org.alfresco.web.bean.repository.NodePropertyResolver;

public class CustomBrowseBean extends BrowseBean{

   /**
    * 
    */
      
   private static final long serialVersionUID = 1L;
   public static QName PROPERTY_SELECCIONADO = QName.createQName("extension.dm", "propSelected");
   @Override
   public List<Node> getContent() {
      
         List<Node> list= super.getNodes();
      for(int i=0;i<list.size();i++)
      {
         list.get(i).addPropertyResolver("selected",resolver);
      }
      
      return list;

   }
   
   public NodePropertyResolver resolver = new NodePropertyResolver() {
         /**
          *
          */
         private static final long serialVersionUID = 903502146868126457L;

         @Override
         public Object get(Node node) {
            boolean selected = DefaultTypeConverter.INSTANCE.booleanValue(getNodeService().getProperty(node.getNodeRef(), PROPERTY_SELECTED));
            if(selected){
               return true;
            }else{
               return false;
            }
         }
   };
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

[cybermakoki]

I've correct the mistake, but the problem is still there,

I'me getting the same error: Base is null: r

I think that the richlist is getting the checkbox as if there is only one checkbox… when i select one and submit the form, all the checks are checked…
