Extending UIX components

Question

Hi everybody,
I've started to investigate the UIX extension possibilites, and I have some doubts.
Here goes some questions:
1) How can I use the new defined components at design time? (I haven't found it in the docs)
2) The documentation talks about the possibility of extend components developed by someone else. And there is an example of adding a new property to an existing component, but the fact is that the new behavior doesn't affect rendering. It's possible to modify the renderization of an existing component in an easy way? For instance, add a new property to a MessageTextInput which lets us decide where goes the promp (left or right of the text box). It's not a great change, but it's needed to modify the renderization.
Thank you,

You should take a look into templates. Templates provide an easy way to customize components (to some extent) and to combine existing components into new ones. So if it can be done with a template then that is probably the way you should go.
In your case, you could create a new template consisting of a messagePrompt and a textInput in a layout. As base type you should use the textInput.
The position of the prompt you could then control based on an additional template attribute.
The templating stuff should also be in the "Extending UIX" chapter.
