generate UI with binding-attribute

[nimo frey]

I want to generate a HTML-PanelGrid in JAVA:

public class Grid
{
    private HtmlPanelGrid htmlPanelGrid;
    private HtmlOutputLabel outputLabel;
    private HtmlSelectBooleanCheckbox selectBooleanCheckbox;
 
   // getter/setter for all components
  ....
 
public Grid() { }
 
public Grid(HtmlPanelGrid htmlPanelGrid, HtmlOutputLabel outputLabel, HtmlSelectBooleanCheckbox selectBooleanCheckbox) {
                super();
                this.htmlPanelGrid = htmlPanelGrid;
                this.outputLabel = outputLabel;
                this.selectBooleanCheckbox = selectBooleanCheckbox;
 
                List<UIComponent> children = htmlPanelGrid.getChildren();
 
                Application application = FacesContext.getCurrentInstance().getApplication();
 
                 for (int count = 0; count < 10; count++)
                  {
 
                  outputLabel = (HtmlOutputLabel) application.createComponent(HtmlOutputText.COMPONENT_TYPE);
                  selectBooleanCheckbox = (HtmlSelectBooleanCheckbox) application.createComponent(HtmlSelectBooleanCheckbox.COMPONENT_TYPE);
                  outputLabel.setValue(" " + count + " ");
                  outputLabel.setStyle("color: blue");
                  selectBooleanCheckbox.setId("hallo"+count);
                  selectBooleanCheckbox.setLabel("hallo"+count);
 
                  children.add(outputLabel);
                  children.add(selectBooleanCheckbox);
 
        }
        }
 

and reference this in a JSF-Page:

<h:panelGrid binding="bean.grid"/>

but I get the following stacktrace:

javax.el.PropertyNotWritableException: /grid.xhtml @279,45 binding="bean.htmlPanelGrid": Illegal Syntax for Set Operation

What is wrong?

Do you see the difference? Which one is correct? Fix it accordingly.

code:
javax.el.PropertyNotWritableException: /grid.xhtml @279,45 binding="bean.htmlPanelGrid": Illegal Syntax for Set Operation

This is because your bean class does not have a set and get method for the property htmlPanelGrid.

You should have a set and get methods (maybe setHtmlPanelGrid(HtmlPanelGrid htmlPanelGrid) and getHtmlPanelGrid()).

And the syntax in your jsf page should be binding="#{bean.htmlPanelGrid}"
