Where am I going wrong?

Hi,

Thanks for considering Aspose.

Could you please post some sample code for which this problem is occurring.

private void btnOk_Click(object sender, System.EventArgs e)

System.Collections.Hashtable result=new Hashtable();

IEngine engine=Session["Engine"] as IEngine;

Hello,

1. Could you send me your xpdl file?

2. Could you help to show me the content of the

  process,variabledefinitionid, variablevalue
 FROM [dbo].[processdata]

Thanks a lot

Hi,the xpdl is attached herewith as .txt file plz rename it to .xpdl and here is the data from the processdata table as you requested.

Hello,

It looks like the reviewer is not in the context. but your program is assigned a value to the reviewer.

I am still working on it to locate the root of this issue. I will keep you posted when I get more details.

Thanks a lot.

Hi,

Is there anything missing with the xpdl??

Yes, if you open the xpdl with the workflow designer ship with the Aspose.workflow. You can see that there is no reviewer field as the data field.

The designer is located on the designer folder of the setup folder of Aspose.Workflow. Please check it out.

Thanks a lot

In my xpdl, the manager is the reviewer. So do I need to have a separate 'reviewer' data field? Can you plz modify the xpdl and post it here so that I can understand what exactly is going wrong?

Thanks.

If this is the case, you can change your code

result["Manager"]=Session["UserName"];

Thanks,

Hello,

Could you please send me your program? We will help to debug and fix it ASAP.

My mailbox is guangzhou##aspose.com (replace the## with @).

Thanks for your help.
