Method Details

bind

public void bind(Component component)

Can be bound to Forms only.

Overrides:

bind in class Behavior

Parameters:

component - the component to bind to

Throws:

WicketRuntimeException - if component is not a form

error

public void error(FormComponent<?> fc)

Reports an error against validatable using the map returned by variablesMap()for variable interpolations and message key returned by resourceKey().

Parameters:

fc - form component against which the error is reported

error

public void error(FormComponent<?> fc,
 String resourceKey)

Reports an error against the validatable using the given resource key

Parameters:

fc - form component against which the error is reported

resourceKey - The message resource key to use

error

public void error(FormComponent<?> fc,
 Map<String,Object> vars)

Reports an error against the validatable using the given map for variable interpolations and message resource key provided by resourceKey()

Parameters:

fc - form component against which the error is reported

vars - variables for variable interpolation

error

public void error(FormComponent<?> fc,
 String resourceKey,
 Map<String,Object> vars)

Reports an error against the validatable using the specified resource key and variable map

Parameters:

fc - form component against which the error is reported

resourceKey - The message resource key to use

vars - The model for variable interpolation

variablesMap

protected Map<String,Object> variablesMap()

Gets the default variables for interpolation. These are for every component:

• ${input(n)}: the user's input
• ${name(n)}: the name of the component
• ${label(n)}: the label of the component - either comes from FormComponent.labelModel or resource key [form-id].[form-component-id] in that order

Returns:

a map with the variables for interpolation

resourceKey

protected String resourceKey()

Gets the resource key for validator's error message from the ApplicationSettings class.

Returns:

the resource key based on the form component
