How to know whether current row is new row or from database?

A row or view has four states:

• New
• Modified
• Un-Modified
• Initialized

To get the state using expression: #{row.row.entities[0].entityState}

You can use this expression to control the display or rows in the UI. Like to display new rows in diff colors.

    Ex: #{row.row.entities[0].entityState==0 ? 'background-color:yellow' :  ''} 

Now in RowImpl, you can access the state using:

    Ex: byte entityState = this.getEntity(0).getEntityState() 

How to Get Application module object programmatically

You can use any of the below methods to get the application module programmatically.

>> private EmployeeAMImpl getAm() {

        FacesContext fctx = FacesContext.getCurrentInstance();
        DCBindingContainer dc =
            (DCBindingContainer)fctx.getApplication().getExpressionFactory().createValueExpression(fctx.getELContext(),
                                                                                                   DCBindingContainer.class).getValue(fctx.getELContext());
        return (WorkbenchAMImpl)dc.findDataControl("EmployeeAMDataControl").getApplicationModule();
    }
    

>> private EmployeeAMImpl getAm() {
        
        FacesContext fc = FacesContext.getCurrentInstance();
        Application app = fc.getApplication();
        ExpressionFactory elFactory = app.getExpressionFactory();
        ELContext elContext = fc.getELContext();
        ValueExpression valueExp =
            elFactory.createValueExpression(elContext, "#{data.EmployeeAMDataControl.dataProvider}",
                                            Object.class);
        return (WorkbenchAMImpl)valueExp.getValue(elContext);
    }
