|Oracle Fusion Middleware Tag Reference for Oracle ADF Faces
11g Release 2 (22.214.171.124.0)
UIComponent class: oracle.adf.view.rich.component.rich.RichSubform
Component type: oracle.adf.RichSubform
Naming container: Yes. When referring to children of this component ("partialTriggers",
findComponent(), etc.), you must prefix the child's ID with this component's ID and a colon (':')
The RichSubform represents 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 or if the default attribute is set to true while no other 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.
You should not have a component with immediate set to true in a subform. A Component with immediate set to true will still be validated even though the containing subform is not responsible for submitting the page.
We strongly recommend the use of a single <af:form> per page, and using <af:subform> where you might otherwise be tempted to use multiple forms. Multiple forms require multiple copies of page state, and user edits in forms that aren't submitted are always lost. When a page using subforms is submitted, page state is only written once, and all user edits are preserved.
See the UIXSubform Javadoc for more details on how subforms work.

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.|
|attributeChangeListener||javax.el.MethodExpression||Only EL||a method reference to an attribute change listener. 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 events might include the width of a column that supported client-side resizing.|
|binding||oracle.adf.view.rich.component.rich.RichSubform||Only EL||an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.|
|clientComponent||boolean||Yes||Default Value: false
|customizationId||String||Yes||This attribute is deprecated. The 'id' attribute should be used when applying persistent customizations. This attribute will be removed in the next release.|
|default||boolean||No||Default Value: false
whether the subform should assume it has been submitted. When set to "true", "submitted" will be considered true if no other subform has been submitted.
|defaultCommand||String||Yes||the client id of the command component inside the subform whose action should be invoked by default, when the enter key is pressed with focus inside the subform. This attribute overrides the defaultCommand set on form.
Identifiers are relative to the subform component, and must account for NamingContainers. You can use a single colon to start the search from the root, or multiple colons to move up through the NamingContainers - "::" will pop out of the component's naming container and begin the search from there, ":::" will pop out of two naming containers and begin the search from there, etc.
|id||String||No||the identifier for the component. The identifier must follow a subset of the syntax allowed in HTML:
|rendered||boolean||Yes||Default Value: true
whether the component is rendered. When set to false, no output will be delivered for this component (the component will not in any way be rendered, and cannot be made visible on the client). If you want to change a component's rendered attribute from false to true using PPR, set the partialTrigger attribute of its parent component so the parent refreshes and in turn will render this component.
