Does anyone happen to know of code I can put into a workflow SDK script to check "Add blank to the list" for a list field. Sometimes it gets unchecked when we run the following code against it and I don't know why.

	field.ClearDropDownList();

	// Add list items back to field
	i = 0;
	foreach(var item in listItems) {
		field.Item[++i] = item;
	}
	field.Update();

Also is there a way to enable intellisense in the workflow C# editor? I remember it being included in the past, where I could type "field." and see all the methods.
