I have a question : when we need several variables for function, if
it's possible, what's the syntax ?
function toUpperCase(value1, value2) {
return value2.toUpperCase() + " " value2.toUpperCase();
}

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
