CoreSubform

public class UIXSubform

extends UIXComponentBase

implements javax.faces.component.NamingContainer

UIXSubform is the base abstraction for an independently submittable region of a page. The contents of a subform will only be validated (or otherwise processed) if a component inside of the subform is responsible for submitting the page. This allows for comparatively fine-grained control of which components will be validated and pushed into the model without the compromises of using entirely separate form elements. UIXSubform is a <html:code>NamingContainer</html:code> and therefore IDs can be reused between subforms. <section name="Behavior_of_subforms"> <html:p> A <html:code>UIXSubform</html:code> is considered "submitted" if an event is queued by one of its children or facets for a phase later than "Apply Request Values" (that is, for later than <html:code>decode()</html:code>). The most common example is a (non-immediate) "command" component (like an <h:commandButton> or <tr:commandButton>). </html:p> <html:p> A <html:code>UIXSubform</html:code> will always allow the "Apply Request Values" phase to execute for its children, even when not "submitted", but when not "submitted", the "Process Validations" and "Update Model Values" phases will be skipped. This differs from an ordinary form component, which, when not submitted, does not (and cannot) run "Apply Request Values" either. </html:p> </section> <section name="UIXSubform_and__quot_default_quot_"> <html:p> In some scenarios, there may be buttons (or other components that submit the page) outside of the main content of a page. If this main content is in a UIXSubform, it could not be fully processed whenever those buttons are clicked, since those buttons aren't inside of the UIXSubform. To support this scenario, Apache Trinidad supports a "default" property on UIXSubform. A "default" subform behaves like any other subform in most respects, but if <html:em>no</html:em> subforms are "submitted" - if no subform has an appropriate event come from its children - then all "default" subforms act as if they are "submitted". </html:p> </section>

Events:

Type	Phases	Description
org.apache.myfaces.trinidad.event.AttributeChangeEvent	Invoke Application Apply Request Values	Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change event might include the width of a column that supported client-side resizing.
