    dataModelSelection returning null after modal editing

    Natali Silverio Newbie

      Hello everybody


      I'm working at my first project using seam/jsf. I'm trying to edit values in a modal-form, but when I click on the submit button I get the following exception:


      Can someone help to understand what is going on?


      Thanks


      Exception during request processing: Caused by javax.servlet.ServletException with message: javax.el.PropertyNotFoundException: /parametros.xhtml @103,100 value=${parametros.configuracao2Record.parametro}: Target Unreachable, 'configuracao2Record' returned null on 'br.xxx.admin.core.components.action.ParametrosAction$$javassistseam3'
