    selectBooleanCheckbox always false after paging in datascrol

      Hi,

      I've got a problem where I have a dataTable with a column that contains a selectBooleanCheckbox, bound to a boolean "active" attribute on our Entity. I am using a datascroller to page through the list.

      All the data in the DB is active. The first page loads fine, with the active selectBooleanCheckboxs all ticked. When I move to the next page, the selectBooleanCheckbox are all unticked. If I page back to the original page, the active selectBooleanCheckbox are now all unticked.

      Is there a known issue with paging within the datascroller causing all the selectBooleanCheckbox within the datatable to be set to false?

      Thanks,
      Brad

          Paste you sources please. I write simple example and the checks stores fine.

            Hi,

            I've been able to reproduce it in a trivial example: Here's the source for the action bean:

            package com.synyati.example;

import java.util.List;

/**
 * Example Action Bean.
 */
public interface ExampleAdminAction {

 /**
 * Get the entities.
 * @return the entities
 */
 List<ExampleEntity> getEntities();

}


            package com.synyati.example;

import java.util.ArrayList;
import java.util.List;

import javax.ejb.Remove;
import javax.ejb.Stateful;

import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.Begin;
import org.jboss.seam.annotations.Conversational;
import org.jboss.seam.annotations.Destroy;
import org.jboss.seam.annotations.Factory;
import org.jboss.seam.annotations.FlushModeType;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Scope;
import org.jboss.seam.annotations.datamodel.DataModel;
import org.jboss.seam.log.Log;
import org.jboss.seam.log.Logging;


/** {@inheritDoc} */
@Stateful
@Name("exampleAdmin")
@Conversational(ifNotBegunOutcome = "desktop")
@Scope(ScopeType.CONVERSATION) // this is the default, but I'm choosing to show this explicitly
public final class ExampleActionBean implements ExampleAdminAction {
 @DataModel
 private List<ExampleEntity> entityList;

 private Log log;
 /**
 * Default constructor.
 */
 public ExampleActionBean() {
 log = Logging.getLog(ExampleActionBean.class);
 };


 /** {@inheritDoc} */
 @Factory ("entityList")
 @Begin(join = true, flushMode = FlushModeType.MANUAL)
 public List<ExampleEntity> getEntities() {
 log.trace("getEntities(): entry");
 entityList = new ArrayList<ExampleEntity>();
 for (int i = 0; i < 100; i++) {
 entityList.add(new ExampleEntity());
 }
 log.trace("getEntities(): exit");
 return entityList;
 }

 /** {@inheritDoc} */
 @Destroy @Remove
 public void destroy() {
 log.trace("destroy(): entry/exit");
 }
}

            And here's the dummy Entity: 
            package com.synyati.example;

import java.io.Serializable;

import javax.persistence.Column;

/**
 * Example entity (note: EJB entity annotations are removed for simplicity).
 */
public class ExampleEntity implements Serializable {

 private static final long serialVersionUID = 1L;

 private Boolean stateMandatory;
 private Boolean postcodeMandatory;

 /**
 * Default ctor.
 */
 public ExampleEntity() {
 this.stateMandatory = true;
 this.postcodeMandatory = true;
 }

 /**
 * @return the stateMandatory
 */
 public Boolean getStateMandatory() {
 return stateMandatory;
 }

 /**
 * @param stateMandatory the stateMandatory to set
 */
 public void setStateMandatory(final Boolean stateMandatory) {
 this.stateMandatory = stateMandatory;
 }

 /**
 * @return the postCodeMandatory
 */
 @Column(name = "postcode_mandatory", nullable = false)
 public Boolean getPostcodeMandatory() {
 return postcodeMandatory;
 }

 /**
 * @param postcodeMandatory the postCodeMandatory to set
 */
 public void setPostcodeMandatory(final Boolean postcodeMandatory) {
 this.postcodeMandatory = postcodeMandatory;
 }

 /** {@inheritDoc} */
 public String toString() {
 return "Country = [" + stateMandatory + ", " + postcodeMandatory + "]";
 }
}
