Crm tokens are returning null values

[zahrabatool]

Hi Jonas, 
I tried reusing XRM token with classic plugin code but it seems I am missing something because the token method is returning nulls against each tag. Appreciate if you can help me identify the issue. Thanks. Abbas

following is the code:

using System;
using System.Collections.Generic;
using System.IdentityModel.Metadata;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading.Tasks;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Query;
using System.Dynamic;
using Rappen.XRM.Tokens;
using System.Runtime.CompilerServices;

namespace SamplePlugin
{
public class AccountUpdate : IPlugin
{

    IOrganizationService service; Entity currentEntity;
    IPluginExecutionContext context;
    ITracingService trace;

    

   private void GetOrganization(IServiceProvider serviceProvider)
    {
        try
        {

            context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
            service = ((IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory))).CreateOrganizationService(context.UserId);
            trace = (ITracingService)serviceProvider.GetService(typeof(ITracingService));

        }
        catch(Exception ex)
        { 
        }

    }
    private void GetRecordContext()
    {
        try
        {
            currentEntity = (Entity)context.InputParameters["Target"];
            if (currentEntity.Attributes.Contains("new_groupcode") )
            {
                string groupCode = currentEntity.GetAttributeValue<String>("new_groupcode");
                GetAllChilRecords(groupCode);
            }
        }
        catch(Exception)
        {
            throw;
        }
    }


    private string GetTemplate()
    {
        currentEntity = (Entity)context.InputParameters["Target"];
        var template = currentEntity.Tokens(service, "Your Parent Company Name is {name}");
        return template;
    }   

    private void GetAllChilRecords(String groupCode)
    {

        try
        {
            string fetchXML = @"<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'> 
                <entity name = 'contact' >
                <attribute name = 'fullname' />
                <attribute name = 'telephone1' />
                <attribute name = 'contactid' /> 
                <order attribute = 'fullname' descending = 'false' />
                <filter type = 'and' >
                    <condition attribute = 'parentcustomerid' operator= 'eq' value='{" + currentEntity.Id.ToString() + @"}' /> 
                </filter>
                  </entity>
                </fetch>";

            EntityCollection retrievedContacts = service.RetrieveMultiple(new FetchExpression(fetchXML));
            if (retrievedContacts.Entities.Count > 0)
            {

                foreach (Entity e in retrievedContacts.Entities)
                {
                    Entity contactUpdate = new Entity("contact");
                    contactUpdate["new_groupcode"] = groupCode;
                    contactUpdate["new_text"] = GetTemplate();
                    contactUpdate.Id = e.Id;
                    service.Update(contactUpdate);
                }
            }


        }
        catch (Exception)
        {
            throw;
        }
    }

    public void Execute(IServiceProvider serviceProvider)
    {
        try
        {
            GetOrganization(serviceProvider);
            GetRecordContext();
        }
        catch (Exception)
        {


        }

        //throw new NotImplementedException();
    }



}

Hi - step 1: include also Rappen.XRM.Helpers.
That is the core of my helpers.

You will also need some Microsoft.PowerFx.* assemblies from NuGet.

See details here: https://github.com/rappen/Rappen.XTB.Helper/wiki/XRM-Tokens#how-to-install-it

Thanks Jonas

I am planning to use in Plugins, do you have a sample plugin code which consumes your helper methods to generate the tokens. because currently there is only example on github to consume xrm Tokens.

Thanks

Good idea, I will try to create a sample plugin.
Stay tuned!

Thanks Jonas.
