What should be passed from data element to XDM Object of "value" and "id" property combo, when no values need to be passed?

[MichaelJo13]

Hi,

In the XDM schema there are commonly objects that contain a value/id combination, where "value" is a number which acts as a counter and "id" is a string which contains the actual value or identifier being passed. I'm using a data element to populate both these fields. The thing I'm trying to figure out is what values to pass when I don't need to populate these properties, under specific conditions. If I'm not supposed to populate the fields, what do I return for the 'id" and value? I'm assuming undefined for "id" or should I pass null instead. I'm thinking null may cause issues with data ingestion. Same situation for "value", do I pass 0, undefined or null? 

Thanks!

value for page view = 1 

for cart object for example value of cart ....

_id is self populating so you do not need to care of that. If there is an * in the element then its self populated

Hi Michael, I'm talking about when I don't want to populate the properties, but I decided just to not include the node instead of trying to set values.

Thanks!

THe ones with * are populated automatically. If you do not want to populate some field then do not put any data element into it 

If I do not understand something put a screenshot from Web SDK
