How to use XPages Java code to set valid method of input control inside a custom control?

Question

Ok, this is a weird one.

In XPages my dataSource is a Java Object. A Managed bean or PageController. I\'m using bootstrap via the Ext. Library.

What I\'d

Answer 1

What I do is using a custom validator for the component. For instance,

In my controller class:

public void validateDuration(UIComponent source) {
    // Do my checks...
    // If fails,
    BeanUtils.setControlInvalid(source, "Format Error at date time!");
}

BeanUtils methods to invalidate a specific component and generate a validation error message:

public static void setControlInvalid(UIComponent editableComponent, String message) {
    if(StringUtil.isEmpty(message) || editableComponent==null) return;

    if(editableComponent instanceof EditableValueHolder) {
        ((EditableValueHolder) editableComponent).setValid(false);
        postFacesMessage(editableComponent, FacesMessage.SEVERITY_ERROR, message);
    }

}

public static void postFacesMessage(UIComponent component, Severity severity, String msg) {
    if(StringUtil.isEmpty(msg) || component==null) return;

    FacesContext fc=FacesContext.getCurrentInstance();

    FacesMessage message=new FacesMessage(severity, msg, msg);
    fc.addMessage(component.getClientId(fc), message);
}
