AttributeValidator - Composite tests

I miss 2 options that would make AttributeValidator much more powerful:

• contain the substring (where the substring could be a regexp) rule,
• checkbox to negate rule

But would be great to have the flexibility and options as in TestFilter.

By the way, is it a good idea to put AttributeValidator and TestFilter together, and use a checkbox for selecting to create ports for each rejection or reject at the end with a list of the unmatched rules?

I have faced a couple of workspaces where this enhancement of the AttributeValidator would have been very useful!

Just the ability to choose whether empties/missing/null can be passed alongside an additional test would be useful, even if more complicated conditional tests weren't possible.

Besides the idea @jlutherthomas linked to, this idea also seems to be linked to this idea: https://community.safe.com/s/idea/0874Q000000j0G6QAI/detail

I've built a BulkAttributeValidatorWithMapping, takes external configuration file like SchemaMapper, allows logical testing like Tester (including NOT), can group tests together (composite tests - eg "Attribute A is a number, or Attribute A is blank"; or... "Attribute A is ABC or Attribute B is DEF"), and custom error messages can be entered (each failed test is concatenated onto an error string). It works with un-exposed attributes (designed to work with an upstream SchemaMapper). May take a while to run as it checks each feature against each validation rule.

If anyone is still following this thread and is interested, I'd appreciate any feedback.

How is this still not possible?
