Hi, Antranig, thanks for your help with this.

The code we were asking you about is in the CollectionSpace repository:

The UI in question is basically a big form with a lot of input fields.  
We want to decorate one of the input fields with a small component  
that presents the user with a choice of number patterns. Their choice  
will cause the associated input field to be populated with a new value.

The files in question are in src/main/webapp/js, and are:

The main component on the page, and the one with the model we wish to  
update. It uses a ChangeApplier.

The small component we're using to decorate one of the <input> fields  
on the main page. We want this NumberPatternChooser to update the  
DataEntry's model based on the number pattern that the user chooses.

A wrapper for fluid renderer related stuff. This file is where we  
build the component tree, and pass the ChangeApplier to the decorator  
by adding it to the options. Now we understand that this is not the  
way to do it, but we're not sure what is the appropriate way.

The code is all still a bit sketchy, so don't be surprised if some  
things look a bit odd.
