                                 java.lang.Object newValue)

Determines whether the property of the given widget has changed during the processing of the current request and thus the changes must be rendered in the response. This is done by comparing the current value with the preserved value.

If there is no preserved value, null is assumed.

Parameters:

widget - the widget whose property is to be compared, must not be null.

property - the name of the property under which the preserved value can be looked up. Must not be null.

newValue - the value to compare the preserved value with

Returns:

true if the property has changed, false otherwise

hasChanged

public static boolean hasChanged(Widget widget,
                                 java.lang.String property,
                                 java.lang.Object newValue,
                                 java.lang.Object defaultValue)

Determines whether the property of the given widget has changed during the processing of the current request and thus the changes must be rendered in the response. This is done by comparing the current value with the preserved value.

In case it is the first time that the widget is rendered (it is not yet present on the client side) true is only returned if the newValue differs from the defaultValue. Otherwise the decision is delegated to hasChanged(Widget,String,Object).

Parameters:

widget - the widget whose property is to be compared, must not be null.

property - the name of the property under which the preserved value can be looked up. Must not be null.

newValue - the value that is compared to the preserved value

defaultValue - the default value

Returns:

true if the property has changed or if the widget is not yet initialized and the property is at its default value, false otherwise

replaceNewLines

public static java.lang.String replaceNewLines(java.lang.String input,
