[Wicket-user] Changing an attribute in response to a Link.onClick() method.

[Philip A. Chapman]

Everyone,

I have written a subclass of AttributeModifier that I had hoped to use
to change an element's class attribute based on whether that item has
been selected.  The setSelected(true) is called from a Link.onClick()
event method.   However, when the page reloads, the element's class
attribute has not been modified to "selectedParameter" as I would have
expected.

Any ideas what I am doing wrong?  I do not get any errors.

public class ReportParameterSelectionAttributeModifier extends
        AttributeModifier
{
        // CONSTANTS
        
        private static final long serialVersionUID = 1L;        
        public static final String SELECTED = "selectedParameter";
        public static final String UN_SELECTED = "unselectedParameter";

        // CONSTRUCTORS
        
        public ReportParameterSelectionAttributeModifier()
        {
                super("class", true, new Model(UN_SELECTED));
        }

        // MEMBERS

        // METHODS

        public void setSelected(boolean selected)
        {
                // Just change what is in the model depending on whether
                // the item is selected.
                this.getReplaceModel().setObject(
                                null, selected ? SELECTED : UN_SELECTED
                        );
        }
}
