If I unterstand your answer my question about several variables is not to easy to implement ?

Correct, that's not supported right now. Didn't seem like you would need it for 
your use case and it would have complicated the implementation.

Hi all,

I have just checked in support for this feature. The Property Binding tutorial 
includes a demonstration:

   
http://svn.apache.org/repos/asf/pivot/trunk/tutorials/src/org/apache/pivot/tutorials/databinding/property_binding.bxml

For example:

   function toUpperCase(value) {
       return value.toUpperCase();
   }

   <TextInput bxml:id="textInput" Form.label="Text Input"/>
   <Label Form.label="Uppercase Text" text="${toUpperCase:textInput.text}"/>

There is also an example of creating a mapping in Java:

   
http://svn.apache.org/repos/asf/pivot/trunk/tutorials/src/org/apache/pivot/tutorials/databinding/PropertyBinding.java

You may notice that I chose to use the "foo:bar" syntax to specify a mapping function 
rather than "foo(bar)". I did this for the following reasons:

1) It is easier to parse.

2) It doesn't look like a function, whereas "foo(bar)" does. The user might incorrectly 
assume that "foo(bar)" is an inline function declaration, which it is not (it is never 
actually evaluated by the script engine - the function referred to by this expression is what is 
actually evaluated).

3) It may look like a JavaScript function, but it doesn't look like a Groovy 
closure, for example. If Groovy is being used as the page language, this could 
be confusing.

Let me know if you have any questions or comments.

Thanks!
Greg
