org.apache.shale.clay.component.chain.PropertyValueCommand.execute()

Looks at the {@link AttributeBean} on the {@link ClayContext} to seeif the value is a binding EL. If it is not it just updates the component with the value. If the attribute is a value binding expression, then a ValueBinding is created. If the attribute uses early binding the ValueBinding is executed and result applied to the component. Otherwise, the binding expression is applied to the component in a prepared state. A true value is always returned because this is the default handler.

@param context common chains @return true if the chain is complete @exception Exception propagated up to the top of the chain

        clayContext.setDisplayElement(displayElement);
        // normally done in the AssignChildrenCommand
        clayContext.setSymbols(displayElement.getSymbols());
                
        Command command = new PropertyValueCommand();
        boolean isFinal = command.execute(clayContext);
        assertEquals("command finished", true, isFinal);       
        assertEquals("value = 6743", "6743", child.getValue());      


    
        //create a target component

        displayElement.addSymbol(createSymbol("@{ab}", "43"));
        displayElement.addSymbol(createSymbol("@{a}", "67"));


        clayContext.setChild(child);


        isFinal = command.execute(clayContext);
        assertEquals("command finished", true, isFinal);       
        assertEquals("value = 6743", "6743", child.getValue());

        displayElement.addSymbol(createSymbol("@(ab)", "43"));
        displayElement.addSymbol(createSymbol("@(a)", "67"));
