What is the latest version of DocumentServices that I should be using?

I just removed all of the references with the intention of building them back up one at a time. RA 9.1 is added by default. The compiler complained that it DocumentServices was needed because of my reference in the code, so I added DocumentServices 9.1. Now it's saying the following:

Referenced assembly 'Laserfiche.DocumentServices.dll' could not be resolved because it references the unresolved assembly 'LaserficheImaging.dll'

Due to the way scripts are published it can be a bit of work to add references that have reference other non system .NET assemblies. Just work through the messages and it should work.

As for your original problem, I'll make a note in future workflow upgrades to automatically supply the 'system policy updates' it suggests.

Maybe I'm missing something here. I didn't have to go through all of this when I originally built the workflow. RA was already there, and all I did was add a reference to DocumentServices.

There doesn't appear to be a version of LaserficheImaging that it's happy with.

Could you post the code of your script that uses Document Services?

namespace WorkflowActivity.Scripting.SDKScript
{
    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Data.SqlClient;
    using System.Text;
    using Laserfiche.RepositoryAccess;
    using Laserfiche.DocumentServices;
    using TiburonToPbk; //My custom assembly
    using TiburonToPbk.Models; //My custom assembly
    using System.IO;

    /// <summary>
    /// Provides one or more methods that can be run when the workflow scripting activity is performed.
    /// </summary>
    public class Script1 : RAScriptClass91
    {
        /// <summary>
        /// This method is run when the activity is performed.
        /// </summary>
        protected override void Execute()
        {
            ConnectionWrapperRA wrapper = this.ConnectToRA(ConnectionMethodRA.RepositoryAccess91);

            var srch = new Search((Session)wrapper.Connection);

            //Look for documents with a given case number
            srch.Command = @"{[JCSO Case Files]:[Case Number]=""%(ForEachRow_CaseNumber#<\d{2}>#)-%(ForEachRow_CaseNumber#<\d{2}(\d{5})>#)""}";
            srch.Run();

            SearchResultListing results = srch.GetResultListing(new SearchListingSettings());

            var de = new DocumentExporter();
            var rp = new ReferralPackage(); //An object from my custom assembly

            var docs = new List<DocumentInformation>();

            for(int i = 1; i <= results.RowsCount; i++)
            {
                //Convert the documents to PDF and store in a memory stream
                var ms = new MemoryStream();
                DocumentInfo docInfo = Document.GetDocumentInfo(results.GetEntryInfo(i).Id, (Session)wrapper.Connection);
                de.ExportPdf(docInfo, docInfo.AllPages, PdfExportOptions.IncludeText, ms);

                var doc = new DocumentInformation(); //An object from the custom assembly
                doc.EntryID = docInfo.Id;
                doc.FileName = docInfo.Name;
                //Convert to string for injection into the export package
                doc.FileContent = Convert.ToBase64String(ms.ToArray());

                docs.Add(doc);
            }

            rp.SendReferral((int)GetTokenValue("ForEachRow_ID"), docs);
        }
    }
}

Like I said, this was all working until I needed to republish the workflow that was created under 9 to the Workflow server that is now running 9.1.

Thanks for the script, I'm going to see if I can figure out why the extra references are required. It might take me a little bit of time.

Can you confirm the presence of these files on the WF server and designer machines?

C:\Windows\Microsoft.NET\assembly\GAC_32\LaserficheImaging\v4.0_9.1.0.0__3f98b3eaee6c16a6\LaserficheImaging.dll

C:\Windows\Microsoft.NET\assembly\GAC_64\LaserficheImaging\v4.0_9.1.0.0__3f98b3eaee6c16a6\LaserficheImaging.dll

Interesting. On the designer I have one that's version 8.4. The server has the expected 9.1 versions.

C:\Windows\Microsoft.NET\assembly\GAC_32\LaserficheImaging\v4.0_8.4.0.101__3f98b3eaee6c16a6

C:\Windows\Microsoft.NET\assembly\GAC_64\LaserficheImaging\v4.0_8.4.0.101__3f98b3eaee6c16a6

OK, so double checking the Workflow installer, the Workflow server installs LaserficheImaging 9.1 but the Workflow Designer does not (because its not a dependency for the Designer).

You'll need to find an install that includes it. I believe the 9.1 client install does and the soon to be but not yet released 9.1 SDK.
