Enter NULL as Value in Unique Value Renderer

Question

I'm having a very difficult time adding NULL values to a unique value renderer.  I am using 3 fields and I want to enter in all possible combinations even though I don't have all the values in the data, but it says that <Null> is an invalid type.  I have no idea how they want you to enter NULL manually.  I even tried creating all the values in the data, but the tool to add all values wouldn't add value triplets even though the data was saved and clearly present.  I reentered the data and some values would show up and not others.

Thanks,

Nathan

Hi Dan,

I was able to get it to work by extracting the .aprx and editing the XML.  NULL was stored as <Null> in the XML.

Your values are integers, hence you have to use an integer to represent nodata

Hi Dan,

What I am referring to is how to type in NULL in the UI?  If the NULL values are in the data, it will add them.  If I want to type them in, it says invalid data type if I type in <Null>.
