thanks. it's working, but like this, i always have to overide the
Form.validate() and it won't work with normal Form. What do you think about
this solution:
class MyComponent extends Panel {
private IFormValidator formValidator;
setValidation(...){
formValidator = new IFormValidator(){
public FormComponent[] getDependentFormComponents() {
return null;
}
public void validate(Form form) {
if (checkerrors()) {
error("foo");
}
}
};
}
protected void onBeforeRender() {
if(formValidator != null){
Form form = (Form) findParent(Form.class);
form.add(formValidator);
}
super.onBeforeRender();
}
}
