Most ICEFaces components have a binding attribute and a value attribute. Can anyone explain the difference between these two attributes?
From the ICEFaces API for ice:inputText, here is the definition given:
binding - The value binding expression linking this component to a property in a backing bean
value - The current value of this component. All UIInput derived UIComponents, that are placed within a UIData container, such as a dataTable or panelSeries, should have their value attribute bound to a bean property via a ValueBinding/ValueExpression, since otherwise the UIData container will not keep their successfully validated state, which can cause the component to fail to function properly.
This has got to be one of the most famous all time questions on JSF...
i asked the same question when i started...anyway..here goes your answer..
When you are interested in only the value of a UI element...(the text it holds)..use the value attribute...
When you are interested in the backing the UI element itself , for example, to set the visibility of the UI element in your controller..use binding attribute...because a value attribute will not give you access to the UI element in the backing bean...
To gain further insight into the above explanation..define two UI elements in a JSP...back one using the 'value' attribute and the other using the 'binding' attribute...notice how the 'types' of these attributes differ in the backing bean...and you will have your answer..
