jsf - Combine Faces Flow feature with Ajax -

-

is possible combine new jsf 2.2 faces flow feature ajax?

use case: there wizard embedded in panel on page. user steps through wizard, panel shall updated, not entire page.

i looking down route myself , did research. short answer yes can use ajax both partial view processing , partial view rendering. here working example:

flow definition

@applicationscoped public class myflow implements serializable {      @produces @flowdefinition     public flow defineflow(@flowbuilderparameter flowbuilder flowbuilder) {         flowbuilder.id("", "myflow");         flowbuilder.viewnode("flowp1", "/flowpage1.xhtml").markasstartnode();         return flowbuilder.getflow();     } }

flowpage1.xhtml (first , view in flow):

<html xmlns="http://www.w3.org/1999/xhtml"   xmlns:h="http://xmlns.jcp.org/jsf/html"   xmlns:p="http://primefaces.org/ui"> <h:head>     <title>view within flow ajax test</title> </h:head> <h:body>     <h:form>         <h:panelgrid columns="2">             <p:commandbutton value="flow action method" action="#{myflowbean.flowactionmethod}" update="flowtext"/>             <p:commandbutton value="view action method" action="#{myviewbean.viewactionmethod}" update="viewtext"/>             <h:outputtext id="flowtext" value="#{myflowbean.flowvalue}" />             <h:outputtext id="viewtext" value="#{myviewbean.viewvalue}" />         </h:panelgrid>     </h:form> </h:body> </html>

backing beans

flow-scoped bean

@named @flowscoped("myflow") public class myflowbean implements serializable{      private string flowvalue;      @postconstruct     public void init(){         system.out.println("myflowbean postconstruct");     }      public void flowactionmethod(){         system.out.println("flowactionmethod called");         //flowvalue = "flow value set";     }      public string getflowvalue() {         return flowvalue;     }      public void setflowvalue(string flowvalue){         this.flowvalue = flowvalue;     } }

view-scoped bean

@named @viewscoped public class myviewbean implements serializable {      private @inject myflowbean flowbean;     private string viewvalue;      @postconstruct     public void init(){         system.out.println("myviewbean postconstruct");     }      public void viewactionmethod(){         system.out.println("viewactionmethod called");         viewvalue = "view value set";         flowbean.setflowvalue("flow value set");     }      public string getviewvalue() {         return viewvalue;     } }

navigate flow using "myflow" navigation-case anywhere outside flow. once flowpage1.xhtml has rendered, following demonstrate ajax usage:

  1. press "view action method" button. set value of both bean fields, render view-scoped field. see text view-scoped field.
  2. press "flow action method" button. render flow scoped bean field, displaying value set view bean's action method.

Line ending issue with Mercurial or Visual Studio -

i seem have strange issue caused either visual studio or mercurial. localised single project, i'm guessing in project configuration causing issue. at difficult specify point, when perform action in visual studio, update every line ending in given file, means when @ file in sourcetree, every line has changed. i can replicate using nuget add package dependency; packages.config entirely replaced. if commit changes, including line endings, later same issue occur. workaround have shelve changes , reapply them, whereupon lines written correctly. i'm not sure application blame here. did make mistake of allowing sourcetree change mercurial configuration, issue have fixed, i'm not sure if has persisted. i thought might issue mercurial.ini files or hgrcs don't seem contain untoward. here's mercurial.ini [ui] username = ....
