AW: custom output component in datatable

[Stefan Gesigora]

Hi!

If I use my custom component in the datatable the expressions "#{list.id}" and 
"#{list.isIntern}" are resolved as null values.

Here are the snippets of my TagClasses:

---SNIP--

public abstract class BaseTag extends UIComponentTag{

  /**
   * @param attributeValue String
   * @return String
   */
  public String solveValueBinding(String attributeValue) {
    if (attributeValue != null && isValueReference(attributeValue))
      return getValueBindingVal(attributeValue);
    return attributeValue;
  }

  /**
   * @param attributeValue String
   * @return String
   */
  private String getValueBindingVal(String attributeValue) {
    FacesContext context = FacesContext.getCurrentInstance();
    ValueBinding vb = 
context.getApplication().createValueBinding(attributeValue);
    return (String) vb.getValue(context);
  }

}


package com.dsa.qms.web.components;

import javax.faces.component.UIComponent;

public class EmployeeTag extends BaseTag{

  private String readOnly;
  private String partIntern;
  private String roleAbbrev;
  private String partId;
  private String totalStyleClass;
  private String descLeftStyleClass;
  private String descRightStyleClass;
  private String selectBoxStyleClass;
  private String contentStyleClass;


  public EmployeeTag () {
  }

  /**
   * @return String
   */
  public String getComponentType() {
    return "Employee";
  }

  /**
   * @return String
   */
  public String getRendererType() {
    return null;
  }

  protected void setProperties(UIComponent component) {

    super.setProperties(component);
    EmployeeComponent employeeComponent = (EmployeeComponent) component;

    employeeComponent.setReadOnly( new  
Boolean(solveValueBinding(readOnly)).booleanValue() );
    employeeComponent.setPartIntern( new        
Boolean(solveValueBinding(partIntern)).booleanValue() );
    employeeComponent.setRoleAbbrev(solveValueBinding(roleAbbrev));
    employeeComponent.setPartId(solveValueBinding(partId));
   employeeComponent.setTotalStyleClass(solveValueBinding(totalStyleClass));
    
employeeComponent.setDescLeftStyleClass(solveValueBinding(descLeftStyleClass));
    
employeeComponent.setDescRightStyleClass(solveValueBinding(descRightStyleClass));
    
employeeComponent.setSelectBoxStyleClass(solveValueBinding(selectBoxStyleClass));
    
employeeComponent.setContentStyleClass(solveValueBinding(contentStyleClass));

  }

  public void release() {
    super.release();
    readOnly = null;
    partIntern = null;
    roleAbbrev = null;
    partId = null;
    totalStyleClass = null;
    descLeftStyleClass = null;
    descRightStyleClass = null;
    selectBoxStyleClass = null;
    contentStyleClass = null;

  }

  public void setRoleAbbrev(String roleAbbrev) {
    this.roleAbbrev = roleAbbrev;
  }

  public void setReadOnly(String readOnly) {
    this.readOnly = readOnly;
  }

  public void setContentStyleClass(String contentStyleClass) {
    this.contentStyleClass = contentStyleClass;
  }

  public void setDescLeftStyleClass(String descLeftStyleClass) {
    this.descLeftStyleClass = descLeftStyleClass;
  }

  public void setTotalStyleClass(String totalStyleClass) {
    this.totalStyleClass = totalStyleClass;
  }

  public void setDescRightStyleClass(String descRightStyleClass) {
    this.descRightStyleClass = descRightStyleClass;
  }

  public void setSelectBoxStyleClass(String selectBoxStyleClass) {
    this.selectBoxStyleClass = selectBoxStyleClass;
  }

  public void setPartId(String partId) {
    this.partId = partId;
  }

  public void setPartIntern(String partIntern) {
    this.partIntern = partIntern;
  }

  public String getRoleAbbrev() {
    return roleAbbrev;
  }

  public String getReadOnly() {
    return readOnly;
  }

  public String getContentStyleClass() {
    return contentStyleClass;
  }

  public String getDescLeftStyleClass() {
    return descLeftStyleClass;
  }

  public String getTotalStyleClass() {
    return totalStyleClass;
  }

  public String getDescRightStyleClass() {
    return descRightStyleClass;
  }

  public String getSelectBoxStyleClass() {
    return selectBoxStyleClass;
  }

  public String getPartId() {
    return partId;
  }

  public String getPartIntern() {
    return partIntern;
  }

}

IMO there is nothing wrong with the two methods you have posted.

Can you post the getter methods for partId and partIntern?
What happens if you use it in the datatable?
