Vihang's Re-hosting Workflow Designer example errors

  Jon,

  I have already done that and am still getting the error. I can send you the code if you want to see the error for yourself

  My point was that you *will* have to create an implemenation of that interface and put it into the context of your designer to not get that error.

  Jon,

  I am still getting the same errors. This template causes error when running my code.

  I commented out certain things in this template so that I can run the code, but I get the same errors when trying to access properties via the UI designer.

  Let me know if you want to see the code with your template that is not working as expected

  Thanks in advance,

  John Portnov

  John - this may or may not be a helpful answer :) But you will find this will almost every sample out there. At some point - something in the designer is going to use a "service" that isn't installed in the designer context.

  In fact the WF architecture of services and the designer services architecture are very similar in this respect.

  I'd recommend implementing that interface and adding it to the services that are available in your designer.

  Here is a template - the implementation is up to you really, although you could just take out the exceptions and it will work and be a no-op service. I am guessing the method that is being called is NavigateToProperty. You'll have to add this as a service (I generally do this in my WorkflowLoader.Initialize).

  public class ExtendedUIService : IExtendedUIService

  {

  #region IExtendedUIService Members

  public void AddAssemblyReference(System.Reflection.AssemblyName assemblyName)

  {

  throw new Exception("The method or operation is not implemented.");

  }

  public void AddDesignerActions(DesignerAction[] actions)

  {

  throw new Exception("The method or operation is not implemented.");

  }

  public DialogResult AddWebReference(out Uri url, out Type proxyClass)

  {

  throw new Exception("The method or operation is not implemented.");

  }

  public Type GetProxyClassForUrl(Uri url)

  {

  throw new Exception("The method or operation is not implemented.");

  }

  public ITypeDescriptorContext GetSelectedPropertyContext()

  {

  throw new Exception("The method or operation is not implemented.");

  }

  public Uri GetUrlForProxyClass(Type proxyClass)

  {

  throw new Exception("The method or operation is not implemented.");

  }

  public Dictionary<string, Type> GetXsdProjectItemsInfo()

  {

  throw new Exception("The method or operation is not implemented.");

  }

  public bool NavigateToProperty(string propName)

  {

  throw new Exception("The method or operation is not implemented.");

  }

  public void RemoveDesignerActions()

  {

  throw new Exception("The method or operation is not implemented.");

  }

  public void ShowToolsOptions()

  {

  throw new Exception("The method or operation is not implemented.");

  }

  #endregion

  }

  I did not implement it. I used the Re-hosting example that Vihang posted and updated it to be an xoml editor. The issue is with updating properties for a workflow activity (binding to some properties does not work when using the designer re-hosting code).
