Excludes columns are still validated

[mmukundan2005]

Exclude columns are still validated if the columns have blanks though it states that #default validator is used for not excluded columns for which no other validation rule is set
Code: excludes: ["L","M"]

Only if I remove the below code, the column validations excluded

default:
- NotBlank:
message: Value can not be blank

ok thank you for noticing this, looks like default validator is too default :)
Will try to check / fix this some day - not soon
