TableNumberField.HideResult throwing error

[Natalie Westphal]

Hello, 

I am using the following code and it is throwing a system.indexOutOfRange error. 

Can you please advise on why this is happening and if there is a fix? 

 

var tableNumberField = paragraph.AppendField("Table", FieldType.FieldSequence) as WSeqField;

 tableNumberField.HideResult = true;

Thanks,

Natalie
