Examples of org.apache.tapestry5.services.BindingFactory.newBinding()

org.apache.tapestry5.services.BindingFactory.newBinding()

Creates a new binding instance.

The binding represents a connection between the container and the component (the component is usually the child of the component, though in a few cases, it is the component itself). In most cases, the expression is evaluated in terms of the resources of the container and the component is ignored. @param description of the binding, such as, "parameter foo" @param container the component, as represented by its resources, for which a binding is to be created. @param component the component whose parameter is to be bound by the resulting binding (rarely used) @param expression @param location from which the binding was generate, or null if not known @return the new binding instance


        BindingSource source = new BindingSourceImpl(map);


        try
        {
            source.newBinding(description, container, component, defaultPrefix, expression, l);
        }
        catch (TapestryException ex)
        {
            assertEquals(ex.getMessage(), "Parameter 'wilma' must have a non-empty binding.");
            assertSame(ex.getLocation(), l);

        {
            public void run()
            {
                train_isBound(resources, "value", false);


                expect(source.newBinding("default value", resources, BindingConstants.PROP,
                                         "literal:greeting")).andReturn(binding);


                resources.bindParameter("value", binding);


                train_isInvariant(resources, "value", true);
