Joiner plugin wont work if stagename or field name has '.' character in it.
Description
Joiner relies on user input for the join keys and aliases. The format for input is <stage_name.field_name>. However we do allow '.' character in the stage name and field names in which case Joiner wont be able to figure out the stage name and field name unambiguously.
