Spirng 3 + WebFlow 2.3 + JSF 2.0 required input text lost data after validation

[feriale_nplust]

Hi all
I have a very strange problem regarding input text validation using Spring 3.0, Sprign Web Flow 2.3 and JSF 2.0.

Once the form has been submitted, if JSF validation phase fails( the fields are required ) the server lost data applied on the rendering response.

I suppose some library are missing:
- com.springsource.com.sun.faces-2.0.0.PR2.jar
- com.springsource.javax.faces-2.0.0.PR2.jar
but if i insert them the application does not startup anymore.

The attacched file "Build.xml" list all dependencies used by the project.

Please help me out this problem.

Alex

can anyone help me out this tedious problem?
Is there a simple webapp with Spring 3, Spring WebFlow 2.3 and JSF2.0 running?

Thanks a lot
Alex
