[jboss-user] [JBoss Seam] - Validating initial input parameters for a pageflow

I would like to require an initial set of request parameters that get passed into a pageflow. Depending on whether those parameters are valid, I'd like to redirect to an error page. Ideally, I'd like to map those parameters to a model and use annotations to define the validation rules. Does anyone have any advice on the cleanest way of doing this? The three biggest questions in my head are: 1) how do I map the initial set of parameters to a model because I can't use the h:inputText at this point? 2) if I were to get it in a model how could I manually run the validation rules on the model within a decision node? 3) is it even possible to start a flow with a decision? All of the examples I have seen begin with a start-page. These questions admittedly imply a very specific approach to the problem. I am open to any other suggestions that would provide the same result. Thanks in advance, Daniel View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4005381#...
