Try to use data attribute of a4j:commandButton in your oncomplete method.

data

false

false

javax.el.ValueExpression (must evaluate to java.lang.Object)

Serialized (on default with JSON) data passed on the client by a developer on AJAX request. It's accessible via "data.foo" syntax

thanks for the tips lIya, i solved this with java script : 

<script type="text/javascript">

                function showModal(validatedForm) {

                    if(validatedForm == 'true') {

                        Richfaces.showModalPanel('selectcountries_panel');

                    }

                }

            </script>
