I am building a custom transformer that returns to the user one to many road characteristics. I have a Choice with Alias (Multiple) User Parameter that allows the user to choose 1 to Many road characteristics. My issue is that attributes from characteristics that they did not choose are showing up in the Output.
I’ve tried BulkAttributeRemover with Regex. NullAttributeMapper after the custom transformer to remove the ‘missing’ attributes, but it requires the user to select each attribute to remove. I generated a List in the FeatureMerger that I am using to merge the records back together. When the data comes thru the Output the List looks correct, but when I explode the list, the extra attributes show up.
I’m sure there is a more elegant way to remove these extra attributes.
Thanks.
