You can easily... here is a simple example, you can improvize from there:
public class FeedbackStyler extends AttributeModifier {
/**
* @param formComponent
* @return FormComponent<?>
*/
public static FormComponent<?> add(FormComponent<?> formComponent) {
formComponent.add(new FeedbackStyler(formComponent));
return formComponent;
}
/**
* @param formComponent
*/
private FeedbackStyler(FormComponent formComponent) {
this(formComponent, null);
}
/**
* @param formComponent
* @param defaultStyle
*/
public FeedbackStyler(FormComponent formComponent, String defaultStyle) {
super(WebPageConstants.STYLE, true, new
FeedbackStyleModel(formComponent, defaultStyle));
}
/**
* @see
org.apache.wicket.AttributeModifier#isEnabled(org.apache.wicket.Component)
*/
@Override
public boolean isEnabled(Component component) {
return !Utils.isEmpty((String) getReplaceModel().getObject());
}
}
public class FeedbackStyleModel extends AbstractReadOnlyModel<String> {
private final FormComponent<?> formComponent;
private String defaultStyle;
private ComponentFeedbackMessageFilter componentFeedbackMessageFilter;
/**
* @param formComponent
* @param defaultStyle
*/
public FeedbackStyleModel(FormComponent<?> formComponent, String
defaultStyle) {
this.formComponent = formComponent;
this.defaultStyle = defaultStyle;
}
/**
* @see org.apache.wicket.model.AbstractReadOnlyModel#getObject()
*/
@Override
public String getObject() {
boolean inError = 0 < TakpSession.get().getFeedbackMessages().messages(
getComponentFeedbackMessageFilter()).size();
if (inError) {
return "border: red solid 1px;" + Utils.noNull(getDefaultStyle());
}
return "" + Utils.noNull(getDefaultStyle());
}
/**
* @return IFeedbackMessageFilter
*/
protected IFeedbackMessageFilter getComponentFeedbackMessageFilter() {
if (componentFeedbackMessageFilter == null) {
componentFeedbackMessageFilter = new ComponentFeedbackMessageFilter(
formComponent);
}
return componentFeedbackMessageFilter;
}
/**
* @return the defaultStyle
*/
public String getDefaultStyle() {
return defaultStyle;
}
/**
* @param defaultStyle
* the defaultStyle to set
*/
public void setDefaultStyle(String defaultStyle) {
this.defaultStyle = defaultStyle;
}
}
