Views rendered as a cell do not receive params in the same manner.
Subviews (rows) need all of the information of the row entry within data.
Cells need only the piece of information from that row where the key within data matches columns[x].field.
Tat content is then passed along and will be received within the value object. See this post.
So in the View being used for the cell, you should have just WorkOrderNumber as a child of value, without the extra value object in between.
