Constructor Detail

UISelectMany

public UISelectMany()

Construct an instance of the UISelectMany.

Method Detail

getSelectedValues

public Object[] getSelectedValues()

setSelectedValues

public void setSelectedValues(Object[] selectedValues)

getValueBinding

public ValueBinding getValueBinding(String name)

Deprecated. Use getValueExpression instead

Description copied from class: UIComponentBase

Get the named value-binding associated with this component.

Value-bindings are stored in a map associated with the component, though there is commonly a property (setter/getter methods) of the same name defined on the component itself which evaluates the value-binding when called.

Overrides:

getValueBinding in class UIComponentBase

setValueBinding

public void setValueBinding(String name,
                   ValueBinding binding)

Deprecated. Use setValueExpression instead

Description copied from class: UIComponentBase

Put the provided value-binding into a map of value-bindings associated with this component.

Overrides:

setValueBinding in class UIComponentBase

getValueExpression

public javax.el.ValueExpression getValueExpression(String name)

Overrides:

getValueExpression in class UIComponent

setValueExpression

public void setValueExpression(String name,
                      javax.el.ValueExpression binding)

Overrides:

setValueExpression in class UIComponent

compareValues

protected boolean compareValues(Object previous,
                    Object value)

Overrides:

compareValues in class UIInput

Returns:

true if Objects are different (!)

validateValue

protected void validateValue(FacesContext context,
                 Object convertedValue)

Overrides:

validateValue in class UIInput

validate

public void validate(FacesContext context)

First part is identical to super.validate except the empty condition. Second part: iterate through UISelectItem and UISelectItems and check current values against these items

Overrides:

validate in class UIInput

getConvertedValue

protected Object getConvertedValue(FacesContext context,
                       Object submittedValue)

Description copied from class: UIInput

Convert the provided object to the desired value.

If there is a renderer for this component, then call the renderer's getConvertedValue method. While this can of course be implemented in any way the renderer desires, it typically performs exactly the same processing that this method would have done anyway (ie that described below for the no-renderer case).

Otherwise:

• If the submittedValue is not a String then just return the submittedValue unconverted.
• If there is no "value" value-binding then just return the submittedValue unconverted.
• Use introspection to determine the type of the target property specified by the value-binding, and then use Application.createConverter to find a converter that can map from String to the required type. Apply the converter to the submittedValue and return the result.

Overrides:

getConvertedValue in class UIInput

getFamily

public String getFamily()

Overrides:

getFamily in class UIInput
