    HtmlCommandButton - created programmatically - will not be displayed

    Andreas Milinski Newbie
      Hi guys,

      I need your help. Can't find any hints for a solution.

      At first same relevant informations:
      I'm using jbosseap-5.0.0-GA, Icefaces 1.8.2, Seam 2.0.

      Now to my problem:

      I want to create a HmtlCommandButton programmatically and bind it via component binding within a template. The get-methode for the HtmlCommandButton will be called two times within the render-response phase, but the button will not be displayed. When I change the get-method in that way, that it will return a new instance of HtmlCommandButton on calling the get-method the second time, the button will be displayed.

      Now to my questions:
      1. Is it a solid matter of the seam/jsf lifecycle, that the get-method of the created htmlcommandbutton will be called two times?
      2. What is the error?

      The code:

      import javax.faces.component.UIComponent;
      import javax.faces.component.UIViewRoot;
      import javax.faces.context.FacesContext;

      import org.jboss.seam.annotations.Create;

      import com.icesoft.faces.component.ext.HtmlCommandButton;

              HtmlCommandButton       btnSuchen;

              int i                   = 0;
             

              @Create
              public void init() {

                      btnSuchen = new HtmlCommandButton();
                      btnSuchen.setId("btnSuchen");
                      btnSuchen.setImage(Image.BUTTON_SUCHEN_ENABLED);
                      btnSuchen.setDisabled(false);
                      btnSuchen.setVisible(true);
                      btnSuchen.setRendered(true);
              }

              /* Getter and Setter */
              public HtmlCommandButton getBtnSuchen() {

      //              if (i > 0) {
      //                      HtmlCommandButton btnSuchen = new HtmlCommandButton();
      //                      btnSuchen.setId("btnSuchen");
      //                      btnSuchen.setImage(Image.BUTTON_SUCHEN_ENABLED);
      //                      btnSuchen.setDisabled(false);
      //                      btnSuchen.setVisible(true);
      //                      btnSuchen.setRendered(true);
      //
      //                      return btnSuchen;
      //              }
      //              i++;

                      return btnSuchen;
              }
             
              public void setBtnSuchen(HtmlCommandButton btnSuchen){
                      this.btnSuchen = btnSuchen;
              }
      }
