namespace DotNetTools.Workflow.Validators
{

	public class TitleValidator : IValidator
	{
		public void Validate(IDictionary transientVars, IDictionary args, IPropertySet ps) 

		{
			String title = (String)transientVars["working.title"]; 
			if(title == null)
				throw new InvalidInputException("Missing working.title");
			if(title.Length > 30)
				throw new InvalidInputException("Working title too long");
