Set and Get Value from Taskflow parameter (pageFlowScope variable) from Managed Bean- ADF

Hello All

This post is about getting and setting value in taskFlow parameter using Java Code so for that we have created a application with bounded taskFlow

Let's see how to do this -

We have bounded taskflow having Input Parameter defined in it named GLBL_PARAM_TEST

and we have to set its value from managed bean.
this is very simple -see how to do that

• Get pageFlowScope Map and put parameter 's value in it



        Map paramMap = RequestContext.getCurrentInstance().getPageFlowScope();
        paramMap.put("GLBL_PARAM_TEST", "Ashish"); 



• And get Value from taskFlow parameter in managed bean





    public String resolvEl(String data){
               FacesContext fc = FacesContext.getCurrentInstance();
               Application app = fc.getApplication();
               ExpressionFactory elFactory = app.getExpressionFactory();
               ELContext elContext = fc.getELContext();
               ValueExpression valueExp = elFactory.createValueExpression(elContext, data, Object.class);
               String Message=valueExp.getValue(elContext).toString();
               return Message;
             }


String param=resolvEl("#{pageFlowScope.GLBL_PARAM_TEST}");
