Component representing a single radio choice in a org.apache.wicket.markup.html.form.RadioGroup.
Must be attached to an <input type="radio" ... > markup.
STATELESS NOTES: By default this component cannot be used inside a stateless form. If it is desirable to use this inside a stateless form then
- override #getValue() and return some stateless value to uniquely identify this radio (eg relative component path from group to this radio)
-
override
getStatelessHint()
and returntrue

Method Details
-
getValue
Form submission value used for the Htmlvalue
attribute of theinput
tag.If
Radio
s are recreated on each render of theirRadioGroup
, this method should be overridden to return a 'stable' value, otherwise its selection will be lost after aForm
was submitted and resulted inForm.hasError()
.- Returns:
- input value
-
getGroup
- Returns:
- The associated radio group Component
-
onComponentTag
Description copied from class:Component
Processes the component tag. Overrides of this method most likely should call the super implementation.- Overrides:
onComponentTag
in classComponent
- Parameters:
tag
- the abstraction representing html tag of this component- See Also:
-
setLabel
The value will be made available to the validator property by means of ${label}. It does not have any specific meaning to Radio itself.- Overrides:
setLabel
in classLabeledWebMarkupContainer
- Parameters:
labelModel
-- Returns:
- this for chaining
-
getStatelessHint
Returns whether the component can be stateless. Also the component behaviors must be stateless, otherwise the component will be treat as stateful. In order for page to be stateless (and not to be stored in session), all components (and component behaviors) must be stateless.- Overrides:
getStatelessHint
in classComponent
- Returns:
- whether the component can be stateless
-
