getConvertedUISelectManyValue

public static Object getConvertedUISelectManyValue(FacesContext facesContext,
                                                   UISelectMany component,
                                                   String[] submittedValue)
                                            throws ConverterException

Throws:

Gets the converted value of a UISelectMany component. If the considerValueType is true, this method will also consider the valueType attribute of Tomahawk UISelectMany components.

Parameters:

facesContext -

component -

submittedValue -

considerValueType -

Returns:

Throws:

ConverterException

getClassFromAttribute

public static Class<?> getClassFromAttribute(FacesContext facesContext,
                                             Object attribute)
                                      throws FacesException

Gets a Class object from a given component attribute. The attribute can be a ValueExpression (that evaluates to a String or a Class) or a String (that is a fully qualified Java class name) or a Class object.

Parameters:

facesContext -

attribute -

Returns:

Throws:

FacesException - if the value is a String and the represented class cannot be found

getValueTypeConverter

public static Converter getValueTypeConverter(FacesContext facesContext,
                                              UISelectMany component)

Uses the valueType attribute of the given UISelectMany component to get a by-type converter.

Parameters:

facesContext -

component -

Returns:

getSelectItemsValueConverter

public static Converter getSelectItemsValueConverter(Iterator<SelectItem> iterator,
                                                     FacesContext facesContext)

Parameters:

iterator -

facesContext -

Returns:

The first suitable Converter for the given SelectItems or null.

getConvertedStringValue

public static String getConvertedStringValue(FacesContext context,
                                             UIComponent component,
                                             Converter converter,
